Question

cuo+h2 ---- cu + h2o

justify that the following reactions are redox reactions giving reason​

Answer 1

Answer:

Here, the oxidation number of Cu decreases from +2 in CuO to 0 in Cu i.e., CuO is reduced to Cu. Also, the oxidation number of H increases from 0 in H2 to +1 in H2O i.e., H2 is oxidized to H2O. Hence, this reaction is a redox reaction.

Answer 2

Answer:

Redox reaction,

because CuO lost Oxygen to Cu and h2 gains Oxygen to H2O
