Question

Write the types of decomposition reactions with suitable examples

Answer 1

Answer: 1. Thermal Decomposition

E.g. : Caco3 -> cao + co2

2.Electolytic decomposition /electrolysis

E.g. : 2H2O -> 2H2 + O2 ( by electrolysis)

3. Photolytic decomposition/ photolysis

E.g. : 2AgCl -> 2Ag + Cl2

Answer 2

Answer:

when a single reactant decompose into 2 or more products.. this reaction is called as decomposition reaction.

for example-

 CaCO3----------> CaO + CO2
