Question

it is said that "decomposition of calcium carbonate to calciumoxide and carbon di oxide on heating is an important decomposition reaction used in various industries ".Expain How ?

Answer 1

carbon dioxide is used in fire extinguisher and calcium monoxide is used in whitewashing

Answer 2

This kind of decomposition is termed as thermal decomposition .Here heat as the energy for the chemical for the decomposition.

Here calcimum carbonate decompose to give resultant as carbon dioxide and as well as calcium oxide.

In the same way carbon dioxide is decomposed to give  carbon and oxygen .

Calcium oxide after thermal decomposition gives calcium and Oxygen.

This decomposition is done so that the chemicals are broken down to smaller elements in order to react with small elements .
