In the following reactions name the substances which are oxidized and reducedand also mention the oxidizing and reducing agents:

(a) Ca (s) + Cl2 (g) heat ⎯⎯⎯→ CaCl2 (s).

Ans: – In this reaction, Ca is oxidized so it is a reducing a agent. And Cl is reduced then it is a oxidized agent.

(b) 3MnO2 (s) + 4Al (s) heat ⎯⎯⎯→ 3Mn (l) + 2Al2O3 (s).
Ans: – In the upper reaction, Al is oxidized so it is a reducing agent. And MnO2 is reduced so it is oxidizing agent.

(c) Fe2O3 (s) + 3CO (g) heat ⎯⎯⎯→ 2Fe (s) + 3CO2 (g).
Ans: – Here CO is oxidized so it will be a reducing agent and Fe2O3 is reduced so it will be an oxidizing agent.
