उत्तर
Electrical Energy:
It dissociates the reactant in molten or solution state, into ions, which are charged particles and hence respective products are obtained.
Example:
Electrolysis of acidified water.
\[\ce{2H2O ->[electric][current] 2H2 [g] + O2[g]}\]

What is a balanced chemical equation? Why should a chemical equation be balanced?
Is Electrolysis of water an endothermic reaction or an exothermic reaction?
When water is added gradually to a white solid X, a hissing sound is heard and a lot of heat is produced forming a product Y. A suspension of Y in water is applied to the walls of a house during white washing. A clear solution of Y is also used for testing carbon dioxide gas in the laboratory.
(a) What could be solid X? Write its chemical formula.
(b) What could be product Y? Write its chemical formula.
(c) What is the common name of the solution of Y which is used for testing carbon dioxide gas?
(d) Write chemical equation of the reaction which takes place on adding water to slid X.
(e) Which characteristic of chemical reactions is illustrated by this example?
Write the balanced chemical equation of the following reaction.
copper + nitric acid → copper nitrate + nitric oxide + water
