WebHere, 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 H 2 to +1 in H 2 O i.e., H 2 is oxidized to H 2 O. Hence, this reaction is a redox reaction. F e 2 O 3 (s) + 3 C O (g) → 2 F e (s) + 3 C O 2 (g) Let us write the oxidation number of each element ... WebSolution By applying various rules of calculating the oxidation number of the desired element in a compound, the oxidation number of each metallic element in its compound is as follows: HAuCl 4 → Au has 3 Tl 2 O → Tl has 1 FeO → Fe has 2 Fe 2 O 3 → Fe has 3 CuI → Cu has 1 CuO → Cu has 2 MnO → Mn has 2 MnO 2 → Mn has 4 Therefore ...
