Please help unlock this essay Https://www.bartleby.com/essay/Difference-Between-Musical-Theatre-And-Film-Musicals-F3HRC3ECF9LX A musical film is a genre of movie where songs sung by characters are added into the storyline, occasionally complemented by choreography. The musical numbers in these films do not always develop the plot and characters, but they do give the films a more exciting quality. The primary difference between musical theatre and film musicals is the use of extravagant scenery that would be extraordinarily unreasonable for a stage performance. While making movies, the individuals involved have the luxury of being able to shoot multiple takes and have the time to move backgrounds around or change their entire location. Stage performances, on the other hand, must have scenery that can be easily and efficiently moved on and offstage when it is needed. In order to be able to thoroughly comprehend this relatively recent- in the grand scheme of things- form of entertainment, one should understand the history behind these musical films, be aware of some of the “big names” that are well-known, and recognize major titles that revolutionized musical film forever (Scaruffi, P., 2005). Before being able to completely appreciate musical films, one must be aware of their remarkable history and how they came into existence. According to an article written by Cara Schreffler:

Eating Christmas In the Kalahari Article Questions: 1. 2. 3. 4. What is the basis Of the misunderstanding experienced by Lee when he gave an ox for the Christmas feast held by the Kung? The basis Of misunderstanding around the ox was that the ox was big, but had no meat. The ox was an older ox so therefore most Of its meat was gone, it was just skin and bones. And if they didn't get enough to eat, no one would have the energy to get up and dance and enjoy the festivities. But in the end the ox was perfect, it was full Of fat and full Of meat that would be enjoyed by everyone for two nights. And the bones could even be used to make soup for other tribe members. Why do you think the Kung ridicule and denigrate people who have been successful hunters or who have provided them with a Christmas ox? Why do Americans expect people to be grateful to receive gifts? • I thought it was interesting that they ridiculed him for being a successful hunter. But they do it with good intentions, I think it's a great idea because you want the gift giver to be humble and kind. You don't want the person providing the gift to be in their head about it and feel like everyone owes them something. It is not about What you receive in return, it is about doing something good and expecting nothing in return.

Chemistry Lab 7 APEX.pdf?
Chem. Lab 7 1. What is the color ofbromophenol blue in an acid? In a base? It is colored yellow in acid and blue in a base. 2. How did you get the solution to change from blue to yellow? The pH level change affected the change in colors. Low levels Of C02 or acid in solution with bromothymol blue indicator will appear blue. As the level Of C02 or acid increases, it will allow the solution to adopt a yellow hue. 3. Why did the solution change from blue to yellow (What chemical reaction happened)? The chemical reaction is called an indicator. 4. How did you get the solution to change from yellow to blue? The reaction was reversed. 5. Why did the solution change from yellow to blue (What chemical reaction happened)? Since the reaction was reversed the solution changed colors, and this is known as an indicator. 6. After Procedure Step 3, the solution in Well Al was in equilibrium. What happened to the solution in Well Al during Procedure Step 5? Did the equilibrium shift? Explain this on the basis Of the Le Chatelier Principle? Le Chateliers prmciple states that the concentration Of a product is reduced in a chemical reaction that was in equilibrium. The equilibrium shifts to the right to favor the formation Of products. Le Chateliers principle says that chemical reactions in equilibrium experience a disturbance in the reaction conditions that will make the equilibrium to shift in the opposing direction Of the change to restore the steady-state. If the concentration Of a product is reduced, the equilibrium will shift to the left to try to restore the initial amount Of product and achieve the steady-state again. ****** Result for Image/Page 2 ****** 7. Why did the colors in the Wells A1 and A3 change a second time in Procedure Steps 7 and 8? Was this because Of reversible reactions? Yes, due to the nature ofthe reaction.

Copy of Final Beloved Questions?
Beloved Analysis Questions, p. 236-324 (end) 1. 2. 3. 4. 5. 6. How is it that Sethe can now relate to Baby Suggs contemplation Of color? (237) In her final days, Baby Suggs pondered color because she "never had time" before. As an ex-slave and an oppressed individual, Baby Suggs lived in a world Of black and white, figuratively and literally. African Americans also never had a sense Of ownership Of anything, so when she had come to rest, she finally could appreciate colors the world had to offer. This is also the result Of the murder Of Beloved, which essentially destroyed Baby Suggs. She pondered all the colors, but could never get to red, most likely because it reminded her Of Beloved's blood at the time Of her death. What happened to Sethe's mother's face? Interpret this both literally and symbolically. (240) Sethe's mother had worn the bit so many times, that it disfigured her face into looking as if she had a permanent smile. However, this has symbolic significance because she appeared to smile, even when she was not smiling. This represents the taking away Of her vitality and Of her happiness by the white slave masters. It also may represent an irony, in which she wished to be happy, but in reality, was living a terrible life. What's a Saturday girl, and how is Sethe saved from being one? (240-241) Saturday girl is a girl who works at the local slaughterhouse on Saturdays. She almost became one herself following her release from jail, as a way to pay for Beloved's headstone. However, the Bodwins save her from this fate by getting her a cooking job at Sawyer's restaurant. What's significant about Baby Suggs getting knocked down in the Misery? (246-247) Baby Suggs was always afraid Of getting knocked down by a white man in front Of her children. She didn't want her kids to see her get knocked down because it would make them go crazy. However, Suggs witnessed whitemen take down Sethe and subsequently got knocked down by white men. She became depressed. Baby Suggs lost her happiness and pride at this moment where she lost to white men. Why does Denver think Beloved belongs to her (and though it isn't written, there's a suggestion Of exclusivity)? (247) Denver believes Beloved belongs to her and only her because Of their past together. Denver drank Beloved's blood in the process Of being breastfed. She was the only one to accompany Beloved with a favorable attitude when she was merely a Ionesome spirit in the house. Denver believes that this formed an unbreakable connection between the two Of them. What accounts for the shift in style Of these three chapters? Who narrates each one, and what effect is achieved? (235-256) (hint: see last paragraph on p. 235) ****** Result for Image/Page 2 ****** 7. 8. There is a shift between the past chapters and these three as these parts specifically divulge the thoughts Of the women Of 124. These are more streams-of-consciousness, rather than narration Of the past. Each Of these chapters are narrated by a different person. Sethe narrates the first one, Denver the second, and Beloved the third. What are some Of the atrocities committed, during the cramped boat ride described in Beloved's stream-of-consciousness chapter? The slaves depicted in this chapter are left dehydrated and without water. T hey can't even cry because their bodies are so deprived Of it. T hey get thrown into the ocean, and are put into chained collars in a way that is much less than humane. Why is Sixo laughing at his execution? What does he mean by "Seven-O"? (266-270) Sixo is laughing at his execution because he knows that his lover, Thirty-Mile woman has escaped with his unborn baby, "Seven-O". While he is going to die, he knows that a part Of him will still live on in his unborn baby. 9. What's the irony behind Stamp Paid's wife's name? (look up "Queen Vashti" on the Internet) Queen Vashti was Queen Of Persia and the first wife Of Persian King Ahasuerus. She is viewed as an independent-minded heroine in feminist interpretations Of the Purim story as she was banished for her refusal to appear at the king's banquet to show her beauty as the king wished. Stamp Paid's wife's name is ironic because she did not stand up for herself when she was forced to have sex with someone who was not Stamp Paid. IO. What's the meaning behind Sethe's physical transformation? (280-281) Sethe becomes very small and skinny as Beloved grows larger, almost on the verge Of looking pregnant. It represents how her daughter is pulling out her spirit and even physical presence to further herself. Essentially, as Sethe is being drained, Beloved is almost absorbing all Of her. 11. Why does Denver have such difficulty leaving 124? How do Suggs words inspire her? (286-288) Denver has difficulty leave 124 because she has not left in a long time and she does not know anyone who can help her besides Lady Jones and Stamp Paid. She is also afraid Of encountering white people after hearing about all Of the horrible things that some Of them have done. 12. What is meant by Denver's inauguration into the world as a woman? (292) Up until this point, every interaction and experience that Denver has had has been immature. Currently, she is being forced to be responsible and take care Of her other family members. This push to be independent and actually ask others for help shows her development into a mature woman. ****** Result for Image/Page 3 ****** 13. How is the community around 124 a "sweet thorny place"? The community is sweet yet thorny because they have ostracized Sethe and her family for many years after What happened in the shed. However, even though they have harbored a certain resentment against them for many years, they still come together to help Sethe expel a potentially evil spirit from her home. 14. What, ultimately, was Sethe trying to protect Beloved (and all Of her family) from? (295) Sethe was trying to protect all Of her family from being taken into slavery once again. Once she mistook Edward for school teacher (a white and very unforgiving slave master), she jumped into action in a different way than she had eighteen years ago. Instead Of mercy killing her children, she instead chose to act out against this potential intruder and fight him off with an ice pick. 15. How could Sethe, according to Denver, not want Beloved's forgiveness, but her refusal? (297) Denver saw how badly Sethe felt for What she did to Beloved when she was a child. She believes that Sethe was not seeking forgiveness because she wanted to have the punishment she thought she deserved for killing her child. In a parallel to Crime and Punishment, readers saw how Sethe needed that release, the punishment for her deeds. 16. How does Ella claim to understand what Sethe did in the shed? (301-302, 305) Ella understands the rage that Sethe had in that situation, just not her reaction to it. As a slave, she was used by a father and son, so she was very well aware Of the atrocities that were regularly committed, and understood why she wouldn't want her daughter going there, but she believed the reaction to be prideful and misdirected. 17. In answer to Paul D.'s question about Beloved being her sister, Denver says, "At times I think she was—more." How was she "more"? (314) After Beloved has gone, Denver realizes that she was never just a normal girl that had returned to her family. When she tells Paul D that she thinks she was something more she means that in the supernatural sense. She had seen Beloved fall apart at times and exert her influence on others- even suck the life out Of Sethe. She knew that Beloved was something more because these unnatural occurrences that she reflected upon simply had no other explanation. 18. What favor does Paul return to Sethe, in their meeting in Baby Suggs' bedroom? (322) Paul D restores Sethe's will to keep going when she believes the only thing worth caring about is gone. Instead Of leaving her to fend for herself and her sanity, he wishes to put his own story next to hers, and be one with her. 19. What spirit is being described in the final chapter? Consider both a literal and ****** Result for Image/Page 4 ****** symbolic (metaphorical) interpretation. How does this tie into the novel's second epigraph? (323-324, epigraphs) The spirit being described in the last paragraph is that Of Beloved. I think the overall metaphor is not only about Beloved but about all the pain, history, and suffering endured by black people. This novel highlighted the struggles Of African Americans, and Beloved herself seemed to encompass not only the spirit Of the dead child, but the spirits Of all people dating back to slaves in the Middle Passage.

Beloved Questions (Pg. 174-235) What's the inferred connection between the four horsemen who come for Sethe, and the Four Horsemen of the Apocalypse (biblical allusion, do a search online to learn more information)? (174-175, Revelatio?
Beloved Questions (Pg. 174-235) What's the inferred connection between the four horsemen who come for Sethe, and the Four Horsemen of the Apocalypse (biblical allusion, do a search online to learn more information)? (174-175, Revelations 6:1-8) The arrival of the Four Horsemen in the Bible imply the arrival of the apocalypse. The Four Horsemen in this part of the book are from Sweet Home, Sethe's former slave plantation. Their arrival implies they will soon recapture slaves, authorized under the Fugitive Slave Act. Connecting this with the Bible, the arrival of these four men imply the end of Sethe's world - her own apocalypse. These men will take her children away from her, and they will hurt her children. There is nothing worse than this to Sethe, and so she turns to set her plan in action. 2. How does Schoolteacher internalize the actions Sethe has committed against her children? (176) Instead of actually feeling guilt and sorry for the action Sethe has committed, he sees it as a liability. He is angry with his nephew for having tortured Sethe as badly as he did because he feels as though she, and all slaves, are animals that he has the responsibility of keeping from acting like so. He sees Sethe's actions as her going crazy and thinks about what he has lost- a breeding machine and four slaves. 3. What "kind of confusion" had the uncle (Schoolteacher) warned his nephew about? The "kind of confusion" that schoolteacher warned his nephew about was empathy for the slaves, or in other terms, confusing them for human beings. In his eyes, they were subhuman, property even, and so he did not want his nephew confusing them as anything more, as he was showing signs of discomfort whenever Sethe was beat. 4. Analyze the flaws in the argument found at the bottom of p. 177, which summarizes the ideology of those supporting slavery. ("All testimony to .„") This argument is that white people are doing some kind of service to society by owning slaves. They believe, through their own sinister actions, they are taking care of people who are so animalistic, they cannot survive on their own. Clearly, this is morally and absolutely wrong in all senses of the word. Claiming that owning other people is for ****** Result for Image/Page 2 ****** their own good is some twisted way of justifying the most evil thing in history. 5. What event is revealed in this section that shows how Denver might have such a keen sensitivity towards Beloved? It is revealed that Denver breastfed from her mother while she was covered in Beloved's blood. Therefore, she ingested some of her blood, strengthening their bond even further. 6. Why was Paul so dismissive about seeing Sethe's picture in the newspaper? (182-183) What about his repeated denial of her expression? (182-184, 90) Paul D was dismissive about seeing her face in the paper because he was unable to believe that it was her. He was not able to imagine that she had committed a crime of that gravity. He claimed, repeatedly, that those were not her lips. It could be simply because he normally views her in a loving and tender way. To see her mouth in an evil context threw him for a loop. 7. What is "The Look" and why was no warning given to 124? (184-185) "The Look" is an expression held by white men often looking to oppress or capture Blacks or former slaves. In this occasion, the four horsemen entering the town have "The Look," as it is later revealed that they have come to recapture Sethe and her children. The townspeople do not give warning to 124 because they are still upset after the whoop. They are frustrated and jealous at the abundance provided to them at Suggs' party, that they feel no need to warn 124 about the coming slave catchers. 8. What does Paul D. mean by calling Sethe's love "too thick?" (193-194) Paul D meant that Sethe loves her children too much. Her ability to not see right and wrong in a situation because she was clouded by love is dangerous. He does not seem willing to try to understand why she did what she did. Paul simply dismisses it as overbearing and unnecessary, not to mention wrong. 9. How does Sethe justify her decision to slay her children? (190-194) Sethe wanted to kill her children when she had heard that slave captors were coming for her, so that they would never have to experience the horrors of slavery as she had. She did not want her children to live a life worse than death. She thought that they ****** Result for Image/Page 3 ****** would be safe in God's hands. 10. What's the Fugitive Bill? How does it explain, in part, the indifference of the community around 124 to helping Sethe avoid her captors? Using the Internet or an encyclopedia, learn more about the Fugitive Slave Act and the Compromise of 1850. (201) The fugitive bill made all citizens help in the capture of escaped slaves. In order to avoid having Beloved put into slavery, Sethe resorted to killing her in order to avoid the captors. 11. Why is Stamp Paid unwilling or unable to knock on Sethe's door? (202-203) Since Stamp Paid helps many slaves, he always expects just one thing in return: for their homes to be open to him. He likes to be welcomed and feel as though everyone's family is his own. However, as he tries to knock on Sethe's doors, he hears these voices and sound that is unwelcoming. He was bothered by this, and he also felt guilty for telling Paul D about what Sethe had done. 12.1nterpret Suggs final choice, the contemplation of color, metaphorically. How is this fitting? (208-209) Suggs' final choice is metaphorically fitting because of the issues of race that were prevalent at the time. As a black woman herself, to spend the rest of her life contemplating the effect that issues of race had on her life was extremely appropriate, especially considering the fact that they had just ripped away her daughter and granddaughter away from her. Her choice is very much a reflection of a broken and tired woman who simply wants to rest. 13. VMhy does Stamp Paid begin to identify with Baby Suggs and her tiredness? (216-217) Stamp Paid begins to identify with Baby Suggs and her tiredness as Baby Suggs refused to go to the Clearing because she believed they had won but he refused to acknowledge any such victory. 14.iNhy does Stamp Paid feel he owes no debts to anyone? (218) Stamp Paid feels that he owes no debts to anyone because he had to sacrifice his own ****** Result for Image/Page 4 ****** wife when he was younger. She was given to a different, harsher slave owner. After the world took the one thing he loved the most, his debts are completely paid for the rest of his life. 15.How is Stamp Paid's former name significant? Hint: it's a biblical allusion. Read a brief online or encyclopedia summary. (218, online) Stamp Paid's original name is Joshua. In the bible, Joshua is who takes over and leads the Israelites into the Promised Land after Moses' death. It is significant because in some sense, Stamp Paid is the same, taking slaves to the "Promised Land" of their own - freedom. 16.Why does Stamp Paid get riled up over hearing about Paul D.'s living conditions? (219-220) Stamp Paid gets angered when he hears about Paul D's living conditions. After leaving Sethe, Paul D has been sleeping in the local church. No black men/women were willing to offer him a home, showing this lack of community among them. 17.VMhat does the incident between Schoolteacher and Sixo say about justice? (224-225) Justice does not exist for a slave, or for any oppressed person in this time. "Justice" is something that is interpreted by the white masters, meaning that is never truly fair to the slaves. As stated in the novel: "Clever, but schoolteacher beat him anyway to show him that definitions belonged to the definers-- not the defined." doc

Endocrine System Lab Assignment 1. Endocrine glands function by releasing hormones that move through the blood to targets throughout the body. The structures labeled A-J in Figure 2 are true endocrine glands; however, other tissues and organs, like adipose tissue and your kidneys and heart, can also produce hormones. Identify the endocrine glands in the figure and then match them with the hormone(s) they produce by writing the correct letter. Thyroid: c Uterus Thyroid cartilage Of the larynx Trachea Figure 2. Human endocrine glands _B_ Adrenocorticotropic hormone (ACT H) Antidiuretic hormone (ADH) B Aldosterone c Insulin Luteinizing hormone (LH) D Melatonin ****** Result for Image/Page 2 ****** B Cortisol B Epinephrine Estrogen E Follicle stimulating hormone (FSH) B Glucagon Growth hormone (GH) Assignment 2. E Oxytocin Progesterone Prolactin J Testosterone Thyroxine G Thyroid stimulating hormone (TSH) Endocrine disorders can often be difficult to diagnose because many can present very similar symptoms. Diagnosis often requires a combination of lab work and a patient's history. On Table 2, you will see several different endocrine disorders with common physical symptoms and lab results. Use this information to answer the questions below. Table 2: Endocrine Disorders DISORDERS Acromegaly Addison's Disease Cushing;s Syndrome Diabetes Insipidus Hyperparathyroidism Hyperthyroidism SYMPTOMS Enlarged hands and feet, excessive sweating, fatigue, muscle weakness, pain, limited joint mobility Fatigue, increased pigment in the skin, weight loss, muscle weakness Backache, anxiety, muscle weakness, extra fat deposits on the back of the neck and upper back (aka "buffalo hump"), females may experience irregular menstrual cycle Frequent urination, excessive thirst Excessive thirst, weak or broken bones, fatigue, nausea Elevated body temp, extreme sweating, nervousness, rapid heart LAB TEST RESULTS Elevated levels of insulin, growth factor I Low sodium, high potassium, high ACT H, low cortisol in the blood High levels of cortisol in the blood Normal blood glucose level, no glucose in the urine, low ADH level in the blood High calcium and parathyroid hormone levels in the blood High thyroxine and low TSH in the blood ****** Result for Image/Page 3 ****** Hypothyroidism Polycystic Ovarian Syndrome (PCOS) Type I Diabetes Mellitus Type II Diabetes Mellitus Questions: rate, weight loss, irregular menstrual cycle in females Fatigue, muscle weakness, depression, weight gain, low body temperature, intolerant of cold Acne, unwanted hair growth, weight gain, fatigue, infertility, mood changes, sleep problems Frequent urination, excessive thirst, weight loss Frequent urination, excessive thirst Low thyroxine and high TSH in the blood Elevated levels of testosterone and LH, low levels of FSH in blood Glucose in urine, elevated blood glucose, islet cell antibody in the blood Glucose in urine, elevated blood glucose, no islet cell antibody in the blood 1. 2. 3. What is the most frequent physical symptom of the disorders described above? Fatigue, frequent urination and muscle weakness are the most common symptoms. Why are blood tests used to diagnose endocrine disorders? It shows the endocrine hormones, which can help the doctors determine a diagnosis if there is one. Why is it so important to consider age and sex when diagnosing an endocrine disorder? A certain age can determine how much more likely it is to be diagnosed and sex determines which certain hormones could be involved more often. Case Study 1: A 37-year-old woman goes to her doctor and complains of anxiety, muscle weakness, and depression. Which of the disorders listed on the table above could explain her symptoms? What other symptoms might you look for or what other tests might you run to distinguish between these disorders? ****** Result for Image/Page 4 ****** Most likely "Cushing's Syndrome" and "Hypothyroidism". Both disorders have symptoms of muscle weakness but Cushing's Syndrome includes anxiety and Hypothyroidism includes depression. Further study would be done if she either has an irregular menstrual cycle or low body temperature to distinguish the disorders. Case Study 2: A 34-year-old man complains he is tired a lot and he has lost a substantial amount of weight over the past few months. A routine blood test shows low sodium levels, but his blood glucose levels are normal. What test would you order next? Why? What results could help you make a diagnosis? The test order should be "Addison's Disease" due to fatigue and muscle weakness, and check for any change in pigment in the skin that increased. The results would come back with low sodium, high potassium, high ACT H, low cortisol in the blood. Case Study 3: Your patient is a 28-year-old woman who has complained of menstrual irregularities and infertility despite actively trying to get pregnant for 14 months. She also mentioned that she has to wax her face a lot due to hair growth. How would you diagnose this patient? Which lab result may explain the hair growth? What does this patient have to be careful of developing in the future? I would diagnose this person with PCOS because of the elevated levels of testosterone would explain the hair growth. This patient has to be careful of gaining weight and controlling levels of glucose in the future. Case Study 4: A seemingly healthy 42-year-old-man comes into the ED with a broken arm.

Overall there were fewer saccades than words for each line. This could have been caused by the ability to group easier words together that require less effort. b.) Is the average time interval between saccades different when reading an easy passage vs. a challenging passage? Explain Yes, the average time interval between saccades was larger for the challenging passage because complex words require more time to process. c.) Is the average time interval between saccades different when reading the same passage silently vs. aloud? Yes, the average time interval is larger for reading aloud as it takes more time to read, process, and pronounce the word than just passive reading. d.) Are the waveform shapes different between Read Silently 2 and Read Aloud data? Explain Yes, the read aloud data had longer periods between each wave and generally more saccades in each wave. K.

[i.e. which one is negative with respect to the other?] The negative value for the membrane potential is measuring the inside of the cell. b. If a sodium channel opens, will the inside of the cell become more positive or more negative as the sodium ions come in along their concentration gradient? If a Na+ channel open, the inside of the cell will become more positive. Based on your answer to 'a' and 'b', extend the line in the chart to show what c. might happen to the potential when sodium channels open. The membrane will become depolarized. ****** Result for Image/Page 5 ****** -10 -20 -30 -40 > -50 -60 -70 -80 d. 1 2 3 4 5 6 7 Time (milliseconds) 8 9 10 11 Before the sodium channel opened, the membrane was polarized, like a battery (a positive and negative side). After opening the sodium channel, is the cell going to be polarized anymore? After opening the sodium channel, the cell is no longer polarized with a positive side and a negative side. Model 3: A depolarized membrane outside Potassium ion channel inside Critical Thinking Questions Sodium ion channel Na+ 11. What has changed about the sodium channel in this model (compared to model 2)? In the model 3 the sodium channel is open, and model two is not. 12. How does the number of positive ions inside the cell compare with the number outside the cell? Now the number of positive ions on the two sides of the cell are the same. ****** Result for Image/Page 6 ****** 13. Compare this model to model 2 which contained a polarized membrane. Based on the ion distribution in these two models, devise definitions as a group, for the following: Polarized: when there is a charge difference on the two sides of the membrane. Depolarized: When there is not a charge difference on the two sides of the membrane. Application 14. Based on the concentration of potassium ions inside and outside the cell, which way do you think K+ ions would go if the potassium ion channel were to open and the sodium channel were to close? [hint: draw it if you need to] If K+ channels were to open and Na+ channels were to close, K+ would go out of the cell. 15. Would this depolarize or repolarize the membrane? If K+ begins to move out the cell, once again there will be more positive charges on the outside of the cell and this will repolarize.

L. Glycerol, C3H803, is a nonvolatile nonelectrolyte with a density of 1.26 g/mL at 25 oc. Calculate the vapour pressure at 25 oc of a solution made by adding 50.0 mL of glycerin to 500.0 mL of water. The vapor pressure of pure water at 250C is 23.8 torr. Summarising the given information: V(G1ycer01) = 50 mL = 0.05 L V(H20) = 500 mL = 0.5 L T = 25 oc Density(C3H803) = 1.26 g/mL at T = 25 oc PO(Glycerol) = 0 (because glycerol is non-volatile) PO(H20) = 23.8 torr The vapour pressure of the mixture will be entirely due to H20. From Raoult's Law: P(H20) = X(H20) x PO(H20) Where X(H20) is the mole fraction of 1--120. we need the mole fraction of H20. we need to calculate moles of glycerol and H20. mass(glycerol) = 50 mL x 1.26 g/mL = 63 g MW(g1ycer01) = 92.1 g/mol n(glycerol) = 63 + 92.1 = 0.684 mol mass(H20) = 500 g (Iml = lg at 25 00 MW(H20) = 18.0 g/mol = 500 + 18.0 = 27.8 mol X(H20) = 27.8 + (27.8 + 0.684) = 0.976 Applying Raoults law: P(H20) = 0.976 x 23.8 torr = 23.2 torr The vapour pressure of the solution is 23.2 torr. 2. Seawater is about 3.5% (by weight) dissolved solids, almost all of which is NaCl. Calculate the normal boiling point of seawater. The boiling point elevation constant Kb(H20) = 0.51 oc m-l To calculate boiling point elevation: ATb = i x Kb xm 3.5% by weight NaC1 = 3.5 g in 96.5 g H20 (i.e. 0.0965 kg) mass(NaCl) = 3.5 g MW(NaC1) = 58.44 g/mol n(NaC1) = 3.5 + 58.44 = 0.0599 mol m(NaC1) = 0.0599 + 0.0965 = 0.621 m The Van 't Hoff factor i for NaCl is 2 (assuming complete dissociation of Na+ and Cl- ions) ATb = 2 x 0.51 x 0.621 = 0.63 oc. • the boiling point of seawater = 100 + 0.63 = 100.63 oc. 3. The average osmotic pressure of blood is 7.7 atm at 25 oc. What concentration of glucose, C6H1206, will be isotonic with blood? Osmotic pressure = i x [MI x R x T where i = the Van 't Hoff factor [MI = concentration (Molar) R = Ideal gas constant T = Temperature (absolute scale) Given =7.7 atm = 780 kPa T = 25 oc = 298 K R = 8.314 L kPa K-1 mol-l i = 1 for glucose Need to solve for [glucose] [glucose] + (1 x 8.314 x 298) = 0.31 mol L-1 (Notice that units of kPa and K-l cancel) 4. The vapour pressure of water at 25 oc is 3167 Pa. A solution consisting of 18.913 grams of a non-volatile substance in 36 grams of water has a vapour pressure of 2697.6 Pa. What is the molecular weight of the solute? Given: PO(H20) = 3167 Pa mass(H20) = 36 g MW(H20) = 18.0 g mol-l mass(NVS) = 18.913 g (NV S is non-volatile substance) T = 25 oc P(H20) = 2697.6 Pa Use Raoult's Law: P(H20) = X(H20) x PO(H20) to solve for X(H20): X(H20) = P(H20) + PO(H20) = 2697.6 + 3167 = 0.8518 • mole fraction X of Nvs = 1 - 0.8518 = 0.1482 n(H20) = mass + MW = 36 + 18.0 = 2 mol X(NVS) = n(NVS) + {n(NVS) + n(H20)} • 0.1482 = n(NVS) + {n(NVS) + 2} • 0.1482 x {n(NVS) +2} = n(NVS) • 0.1482 x n(NVS) + 0.2964 = n(NVS) • 0.2964 = n(NVS) - 0.1482 x n(NVS) • 0.2964 = n(NVS) x 0.8518 n(NVS) = 0.2964 + 0.8518 = 0.3480 mol Using the mass, we can calculate MW(NVS): MW(NVS) = m(NVS) + n(NVS) = 18.913 + 0.3480 = 54.32 g mol-l
