Answer: The green copper (II) carbonate $(CuCO_3)$ changes to black copper oxide $(CuO)$

$CuCO_3(s)\stackrel{\Delta }\rightarrow CaO(s)+CO_2(g)$

Explanation:

Decomposition is defined as the chemical reaction in which a single compound gives two or more simple substances. It requires energy to break the bonds between reactants, thus is an endothermic process.

Thermal decomposition uses heat for decomposition.

The chemical equation for thermal decomposition of copper (II) carbonate is:

$CuCO_3(s)\stackrel{\Delta }\rightarrow CaO(s)+CO_2(g)$

The green copper (II) carbonate $(CuCO_3)$ changes to black copper oxide $(CuO)$
