Calcium carbonate can be broken

down by heating what. What is the scientific

term for this? (Hint: your answer

should be two words.)

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.
