Copper(II) carbonate undergoes thermal decomposition. One of the pro al decomposition is copper(II)oxide.
State the colour change of the solid seen during the reaction
start colour
end colour
Write a chemical equation for the thermal decomposition of copper(II) carbona​

The green copper (II) carbonate changes to black copper oxide

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:

The green copper (II) carbonate changes to black copper oxide
