Answer 2

Decomposition reaction is mainly useful in extracting pure metals from their ores

1. Thermal decomposition is used for the production of calcium oxide (quick lime) from calcium carbonate which is a major constituent of cement.

Reaction Involved-

CaCO3 (s) → CaO (s) + CO2 (g)

2. Through electrolytic decomposition metals are extracted. Example sodium from sodium chloride.

Molten sodium chloride on passing electricity is dissociated to sodium metal and chlorine gas.

Reaction Involved-

2NaCl → 2Na + Cl2
