H2S + Cl2 → 2HCl + S
The O.N. of S increases from -2 to 0. So it is undergoing oxidation and O.N. of Cl2 decreases from 0 to -1. So it is undergoing reduction. Therefore it is a redox reaction.
CuO + H2 → Cu +H2O
In this redox reaction, CuO is getting reduced to Cu since Oxygen is getting removed. So, the conversion of CuO to Cu is reduction reaction. H2 is getting oxidised to H2O. So, it is oxidation reaction.
Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s)
Oxidation state of Fe changes from 0 to +2 and oxidation state of Cu changes from +2 to 0
