Show that the pressure of a written as the sum of "partial pressures" p,, where p, n, rt/v. these "partial pressures" are purely formal quantities not subject to experimental observation. (from the mechanistic viewpoint of kinetic theory the partial pressure p, is the contribution to the total pressure that results from bombardment of the wall by molecules of species i-a distinction that can be made only when the molecules are noninteracting, as in an ideal gas.) multicomponent simple ideal gas can be

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.
