You are to take the 3.10M ‘acid’ solution that you are given and dilute it to make 100. mL of an acid solution with a molarity of 1.30 M. You are to use a graduated cylinder and a volumetric flask (size of your choosing).You must show ALL WORK for the following question before you begin.

What volume of the original solution do you need?

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.
