Calcium carbonate can break down to form calcium oxide and carbon dioxide. CaCO3 → CaO + CO2 The oxygen atoms on the product side are not balanced because there are only two oxygen atoms in CO2 not balanced because there is only one oxygen atom in CaO. balanced because the total number of oxygen atoms is 3. balanced when a coefficient of 3 is placed in front of CO2.
