Question

. Identify the substances that are Oxidised or Reduced in the following reactions?

(i) C (s) + O2 (g) → CO2 (g)

(ii) H
2+Br2
→ 2HBr

(iii) 4 HCl + O
2.
→ 2Cl
2+ 2H
2O

(iv) ZnO + C → ZnO + C​

Answer 1

Answer:

Each oxygen atom decreases its oxidation number from 0 to –2, so O2 is reduced and is the oxidizing agent. ... Some of the carbon atoms in CO(g) are oxidized from +2 to +4, and some of them are reduced from +2 to 0.
