Question

Name the three types of decomposition reaction and give one example for each.

Answer 1

Decomposition is a type of chemical reaction. It is defined as the reaction in which a single compound splits into two or more simple substances under suitable conditions. It is just the opposite of the combination reaction.
Types of Decomposition Reactions

Thermal decomposition reaction.

Eg 2HgO gives 2Hg + O2

Electrolytic decomposition reaction.

Eg 2H2O on passing electric current gives 2H2 + O2

Photo decomposition reaction.

Eg decomposition of silver salts in presence of sunlight
