You are on a road trip through the mountains, and you notice that the cylinder in your car is not experiencing the same ideal expansion as when you originally calculated it at sea level. Rather than experiencing a change in volume of 488 mL as you calculated at sea level, it is experiencing a change in volume of 442 mL while driving through the mountains, with a total of 0.0727 g of gas phase molecules in the cylinder after the combustion reaction. Assuming that your car is still operating at 100% efficiency (as we assumed throughout the discussion problems on Tuesday), what is different now

The scheme below is from a series of reactions that are part of a synthesis of vitamin a. answer the following questions with reference to this scheme. (i) what is "reagent a"? (ii) draw a step-by-step mechanism which explains the formation of compound c from compound b (iii) which reagents would you use to form compound e from compounds c and d (reagents b and c)? for each reagent suggested above in (ii) explain the role of the reagent in the reaction to (iv) form compound e. you may wish to do this by drawing a mechanism. 1. addition of reagent a но reagent a 2. н,о" thо oh нон-с compound a. compound b. compound c .ch-оh 1. reagent b "сно 2. reagent c сh oh compound e. compound d.
