14. Why should you run a distillation of two liquid rather slowly than wo liquid rather slowly than more rapidly? 15. What would be the effect of lowering pressure on distillation?
list some compounds if lavender oil and how you would extract them (using vacuum distillation and or steam disillation and or normal distilltion)
2. Explain why the vacuum distillation has more advantage than the simple distillation? 3. Give two examples of materials that can be purified by steam distillation. 4. What are the first and second yellow solids in this experiment?
Can you separate enantiomers by a simple distillation column? Can you separate diastereomers by simple distillation column. Explain your answers with detail reasons. Can you separate enantiomers by a simple distillation column? Can you separate diastereomers by simple distillation column. Explain your answers with detail reasons.
In a recent survey of full-time female workers, 43% said that they would rather give up some of their salary for more personal time. Suppose you select a sample of 100 full-time female workers. A. What is the probability that in the sample, fewer than 50% would rather give up some of their salary for more personal time? B. What is the probability that in the sample, between 40% and 50% would rather give up some of their salary for...
Pre-lab questions 1. What is the basis for separation of compounds using distillation? Why is it possible to separate ethanol from water using distillation? 2. What is the difference between simple and fractional distillation? Why does fractional distillation give a much better separation of substances? 3. When is vacuum distillation used, and why is it used? 4. What is an azeotrope? How does this apply to the separation we are doing in this experiment? 5. What intermolecular forces are being...
What are the three main reasons some individuals select CAM therapies rather than traditional allopathic methods of healing? What would be the profile of the most likely candidates to use CAM therapies? What demographic is more prone to using CAM therapies? What possible reasons contribute to this disparity? How does this article contribute to the study of CAM practices? Do you see any outstanding benefits or detractions from the modality discussed in the article in contemporary wellness environments?

4. Why might using "willingness to accept" give different valuations than "willingness to pay" would give? 5. Explain why the "efficient" level of pollution might depend on the initial assignment of Rights. 6. What are some reasons why Coasean bargaining might not lead to an "efficient" level of pollution? (150-300 words)
Explain what effect each of the following mistakes would have on a simple distillation: a) Failure to add a boiling stone. b) Heating the distillation flask too fast. c) Heating the distillation flask to dryness. d)Using a distillation flask that has a maximum capacity equal to the volume of liquid. e) Using a much larger (e.g., 50 mL) distillation flask. f)Putting the thermometer all the way into the liquid in the distillation flask 1. 2. Using Raoult's Law, calculate the...
