Question

Balanced the chemical equation
1) lead dioxide+sulphuric acid-leadsulphate+water+oxygen
2) manganese dioxide+ potassium hydroxide.+oxygen-pottassium manganate+water

Answer 1

Answer:2 MnO

2 + 4 KOH + O

2 → 2 K

2MnO

4 + 2 H

2O

Eo (MnO

2(s) + 4 H+

+ 2 e− ⇌ Mn2+ + 2 H

2O) = +1.23 V

Eo (Cl

2(g) + 2 e− ⇌ 2 Cl−) = +1.36 V
