If calcium carbonate decomposes, the product of the reaction would be calcium oxide and carbon dioxide.
Balanced chemical reaction: CaCO₃(s) → CaO(s) + CO₂(g).
CaCO₃ is calcium carbonate.
CaO is calcium oxide
CO₂ is carbon dioxide or carbon(IV) oxide
Chemical decomposition is the separation of a single chemical compound (in this example calcium carbonate) into its two or more simpler compounds (in this example calcium oxide and carbon dioxide).
Decomposition is reaction where one substance is broken down into two or more simpler substances. Heat is usually necessary to this type of reaction.
