The chemical environment of carbons can be deduced form their chemical shifts. Deduce the relative chemical shifts of the carbons at the labeled positions. (Carbons that are highly shielded have low delta, chemical shift, values.) 1) OH The carbon with the smallest delta value (the most shielded) is The carbon with the largest delta value (the most deshielded) is 2) The carbon with the smallest delta value (the most shielded) is The carbon with the largest delta value (the most deshielded) is

3. (5 points) The average variable cost curve must always be U-shaped. False. The average variable cost curve may initially slope down but need not. However, it will eventually rise, as long as there are fixed factors that constrain production. 4. (5 points) If the demand curve is a linear function of price, then the price elasticity of demand is the same at all prices. False. It varies between different pairs of points along a linear demand curve.

In a recent study, 25 males used a new weight-loss supplement, and all but 7 of them experienced weight loss after two weeks. In the same study, 100 females used the same supplement, and all but 20 of them experienced weight loss after two weeks. Fill in the blanks below to make the most reasonable statement possible. The new weight-loss supplement was more effective on â–¼(Choose one) in the study. That is because only % of them failed to lose weight after two weeks, whereas % of the â–¼(Choose one) failed to lose weight after two weeks.
