Zinc can be reacted with steam using the apparatus shown. When gas A is collected, mixed with air and ignited it gives a small pop. A white solid B remains in the test tube when the reaction has stopped and the apparatus cooled down.

a. Name and give the formula of gas A.

b. (i) Name the product formed when gas A burns in air.

(ii) Write a balanced chemical equation for this reaction.

c. (i) Name white solid B.

(ii) Write a balanced chemical equation to represent the reaction between magnesium and steam.

d. Name two other metals which could be safely used to replace zinc and produce another sample of gas A.

e. When zinc reacts with dilute hydrochloric acid, gas A is produced again. Write a balanced chemical equation to represent this reaction and name the other product of this reaction.
