1. What is an emulsion? How would an emulsion form during a liquid/liquid extraction? 2. Draw the structure for caffeine. What part of caffeine is basic? 3. What form is caffeine in when dissolved in soda? Draw the structure.
Post lab Questions: 1. What is an emulsion? How would an emulsion form during a liquid/liquid extraction? 2. Draw the structure for caffeine. What part of caffeine is basic? 3. What form is caffeine in when dissolved in soda? Draw the structure.
4. When a separatory funnel is shaken too vigorously, an emulsion may form. What would be the best way to quickly (!) break the emulsion?
1. Why is vigorous trituration required to prepare emulsions? 2. Explain the difference between creaming and coalescence. 3. Emulsions are considered to be physically and thermodynamically unstable systems. Describe an approach that can be used to enhance the stability of an emulsion. 4. Using the 4:2:1 method, what are the consequences of not adding in the water all at once during preparation of the primary emulsion?
Why is the emulsion in homogenised milk so much more stable?

Predict the predominant alkene product that would form when 2-bromo-2-methylpentane is treated with sodium methoxide in methanol. If the base were changed to KOC(CH2CH3)3 would the same alkene predominate? If not, why? What would be the structure of this alternate product be, if it formed?
(a) How does the rate of the first stage of emulsion polymerization in the creation of polymer particles be affected if you change from a stryene monkmer to a methyl methacrylate monomer? (b) If you would like a final product with a larger number of particles, which stage of emlusion polymeeization meeds to be enchanced? (c) what about if yiu want the final product to with larger particles?
3. Why do you think obesity should or should not be treated as a disease? Do you think it is really a disease? If so, is it a mental and/or physical one? 4. Define social determinants. Should health care workers focus more on the social determinants or medical issues of obesity? Explain why you think one focus would work better than another. 5. Explain "Health at Every Size Principle". Do you agree with this principal? Do you think health or...
