Question

Chemical reaction of heat on lime stone

Answer 1

The chemical reaction that takes place when limestone is heated is

CaCo3  CaO + CO2.

Decomposition takes place when limestone is heated strongly.

This reaction helps in forming calcium oxide (CaO) and carbon dioxide (CO2).

Therefore, the word equation will be Calcium Carbonate

 Calcium oxide + carbon dioxide This process is known as decomposition.

Answer 2

Answer:

CaCO3 on heating gives CaO +CO2
