Question

what type of reaction is formed when copper oxide combines with hydrogen gas ? define the reaction .​

Answer 1

Explanation:

Copper combines with oxygen to form copper oxide. Following figure shows formation of copper oxide. 2 Cu + O2 → 2 CuO ; CuO + H2 → Cu + H2O If hydrogen gas is passed over this heated material (CuO ) the black coating of the surface turns brown as the reverse reaction takes place and copper is obtained.

Answer 2

Answer:

Copper combines with oxygen to form copper oxide. Following figure shows formation of copper oxide. 2 Cu + O2 → 2 CuO ; CuO + H2 → Cu + H2O If hydrogen gas is passed over this heated material (CuO ) the black coating of the surface turns brown as the reverse reaction takes place and copper is obtained.
