2:12 describe the formation of carbon dioxide from the thermal decomposition of metal carbonates, including copper(II) carbonate

thermal decomposition is the process of breaking down by heating.

On heating metal carbonates thermal decompose into metal oxides and carbon dioxide.

Observation: green powder (CuCO₃) changes to a black powder (CuO)
