Answer:
(a) Oxidation: if a substance gains oxygen or loses hydrogen during a reaction, it is oxidised. Such reaction is known as oxidation.
2Cu + O2 heat → 2CuO
Example1: Copper gains oxygen and gets oxidised.
Example2: Hydrogen gains oxygen and gets oxidised.
(b) Reduction: If a substance loses oxygen or gains hydrogen during a reaction, it is reduced. Such reaction is called reduction.
CuO + H2 heat → Cu + H2O
ZnO + C → Zn + CO
Example1: Here Copper loses oxygen and gets reduced.
Example2: Here zinc loses oxygen and it gets reduced.
ZnO + C → Zn + CO
