प्रश्न
Give one example of an oxidation-reduction reaction which is also a displacement reaction.
उत्तर
CuO + H2 → Cu + H2O
In this reaction, Cu is being displaced from the reaction, so it is a displacement reaction. It is also a redox reaction because CuO is reduced to Cu and H2 is oxidised to H2O.
