Thermal decomposition
Explanation:
Calcium carbonate can be broken down by heating. The following equation represents this chemical change.
CaCO₃(s) ⇒ CaO(s) + CO₂(g)
The scientific term for this process is thermal decomposition.
- Thermal refers to the fact that heat is required.
- Decomposition refers to the kind of reaction in which a big substance breaks down into smaller substances.
