Question

4. In the following redox reactions ,identify the oxidising agent , reducing agent.
(i) 2 Mg ₊ O2 → 2MgO
(ii) CuO ₊ H2→ Cu ₊ H2O
(iii) Fe2O3 ₊ 3CO → 2Fe ₊ 3CO2
(iv) Zn ₊ 2HCl → ZnCl2 ₊ H2​

Answer 1

Oxidizing agent - OA Reducing agent - RA

1) O2 - OA Mg - RA

2) CuO - OA H2 - RA

3) Fe2O3 -OA. CO - RA

4) Zn - OA. hcl. - RA
