Answer

Explanation:

Step1: Identify reactant and products

Calcium carbonate ($CaCO_3$) decomposes into calcium oxide ($CaO$) and carbon - dioxide ($CO_2$). $CaCO_3\rightarrow CaO + CO_2$

Step2: Check atom balance

On the left - hand side, we have 1 Ca, 1 C, and 3 O. On the right - hand side, we have 1 Ca, 1 C, and 1 + 2 = 3 O. The equation is already balanced.

Answer:

$CaCO_3\rightarrow CaO + CO_2$
