When Hydrogen gas is passed over the heated copper oxide, both steam and copper are formed. The balanced chemical equation with the physical state for this reaction is given below. Cu O (s) + H2 (g) ===> heat ==> Cu (s) + H2O (g). It is the oxidation redoc reaction of the reduction reaction.

Answer 2

Explanation:

If hydrogen gas is passed over heated copper oxide, the black coating on the surface turns brown as the reverse reaction takes place and copper is obtained.

The chemical reaction is as follows

CuO + H2 ----------> Cu + H2O
