What do you observe when hydrogen is passed over heated copper oxide?

When hydrogen gas is passed over heated copper oxide (CuO), a black coating present on the surface give reddish-brown colour due to reverse reaction. Consequently, Copper is produced. The redox process, also known as the oxidation-reduction reaction, is the latter.
