Question

Write a chemical equation for each of the following reactions ,write the state symbols.

(i) Zinc metal reacts with aqueous solution of hydrochloric acid to form zinc chloride

solution and hydrogen gas.

(ii) When solid mercury (II) oxide is heated, liquid mercury and oxygen gas are produced​
