The gram specific volume of water is designated vs, g¯=1.00mlg at t=298k. the gram specific volume of the polymer is vp, g¯=0.750mlg . calculate the molar volume of the protein vp¯ . give your answer in si units.

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

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.
