Write a balanced equation for the decomposition reaction described, using the smallest possible integer coefficients. When calcium carbonate decomposes, calcium oxide and carbon dioxide are formed.

1. The balanced equation is given below:

CaCO3 - > CaO + CO2

2. The coefficients are: 1, 1, 1

Explanation:

Step 1:

The word equation is given below:

calcium carbonate decomposes to produce calcium oxide and carbon dioxide.

Step 2:

The elemental equation. This is illustrated below:

Calcium carbonate = > CaCO3

calcium oxide = > CaO

carbon dioxide = > CO2

CaCO3 - > CaO + CO2

A careful observation of the above equation shows that the equation is balanced.

The coefficients are: 1, 1, 1
