Question

In the following reactions name the substances which are oxidized and reduced and also mention the oxidizing and reducing agents:(a) Ca (s) + Cl2 (g) heat ⎯⎯⎯→ CaCl2 (s)(b) 3MnO2 (s) + 4Al (s) heat ⎯⎯⎯→ 3Mn (l) + 2Al2O3 (s)(c) Fe2O3 (s) + 3CO (g) heat ⎯⎯⎯→ 2Fe (s) + 3CO2 (g)

Answer 1

Answer:

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

Ca = oxidized

Cl2 = Reduced

Ca = Reducing agent

Cl2= Oxidizing agent

(b) 3MnO2 (s) + 4Al (s) heat ⎯⎯⎯→ 3Mn (l) + 2Al2O3 (s)

Al = Oxidized

MnO2 = reduces

Al = Reducing agent

MnO2 = Oxidizing agent

(c) Fe2O3 (s) + 3CO (g) heat ⎯⎯⎯→ 2Fe (s) + 3CO2 (g)

Fe2O3 = Reduced

CO = Oxidized

Fe2O3 = Oxidizing agent

CO = Reducing agent
