Answer 2

Explanation:

When copper is burnt in air, it results in the formation of copper oxide which is black in color.

The reaction when copper is burnt in air is as follows.

      $2 Cu(s) + O_{2}(g) \rightarrow 2 CuO(s)$

Composition reactions are the reactions in which two or more reactants react to give a single product. Therefore, the above reaction is a composition reaction.
