Answer:
The reaction is an example of thermal decomposition/ thermal dissociation.
Explanation:
- A chemical reaction in which heat is a reactant is known as thermal breakdown.
- These reactions are endothermic because heat is a reactant, which means they require thermal energy to break the chemical bonds in the molecule.
- When copper carbonate is heated, for example, it decomposes into copper oxide and CO2.
- Copper oxide is black, while copper carbonate is green. During the process, the colour of the liquid changes from green to black.
