Answer

Brief Explanations:

Calcium carbonate ($CaCO_3$) is made of multiple elements (calcium, carbon, oxygen), so it's a compound. Heating it (a chemical process) breaks it into calcium oxide ($CaO$) and carbon - dioxide ($CO_2$), showing it can be broken down by chemical means.

Answer:

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