During a laboratory demonstration, black copper(II) oxide is heated in a stream of hydrogen gas to produce copper metal and water vapour.
The equation for this reaction is:
CuO+H2→Cu+H2O \text{CuO} + \text{H}_2 \rightarrow \text{Cu} + \text{H}_2\text{O} CuO+H2→Cu+H2OExplain, using this equation, which substance has been oxidised in this reaction.
