A Question Pre You are conducting an experiment with two very reactive substances.
One will react with oxygen (O) and other substances in the air, and the
other will react to metal in a container. What type of environment can you
seal them in so they only react with each other?
O A. Seal them in a glass container in an atmosphere of argon (Ar) gas.
O
B. Seal them in a container of soft alkali metal such as lithium (Li), in an atmosphere
of hydrogen (H) gas.
OC. Suspend them in a bromine (Br) solution inside a glass container.
OD. Seal them in a container made of alkali earth metal, such as calcium (Ca).

Explain the relationship between forward and backward reactions in equilibrium, and predict how changing the amount of a reactant (creating a tension) will affect that relationship.

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.
