Question

Write the following in the form of balanced chemical equation calcium carbonate decomposes on heating to form calcium oxide and carbon dioxide

Answer 1

Explanation:

A balanced chemical equation is the equation which contains equal number of both reactant and product molecules.

The equation for calcium carbonate decomposes on heating to form calcium oxide and carbon dioxide is as follows.

 $CaCO_{3}\overset{heat}{\rightarrow}CaO(s)+CO_{2}(g)$

Due to the heat supplied, the bond between calcium and carbonate breaks as a result it gives calcium oxide which is also known as quick lime along with the release of carbon dioxide gas.

Answer 2

CaCO ----->CaO+CO
