Answer

Brief Explanations:

Calcium carbonate ($CaCO_3$) is made of calcium, carbon and oxygen atoms, so it's a compound. Heating it (a chemical process) breaks it into calcium oxide and carbon - dioxide. Physical means can't break it down.

Answer:

It is a compound that can be broken down by chemical means.
