Ncert Exercises & Solutions

Complete the followings equations

1. $PbS (s) + H_{2} O_{2} (aq) \to$

2. $CO (g) + 2 H_{2} (g) \to_{Catalyst}^{Cobalt}$

(i) When PbS react with hydrogen peroxide, then PbSO₄ and water are formed.

PbS (s) + H_{2} O_{2} (aq) \to {PbSO}_{4} + 4 H_{2} O

(ii) When carbon mono-oxide reacts with hydrogen in the presence of cobalt catalyst, then methanol is formed.

CO (g) + 2 H_{2} (g) \to_{Catalyst}^{Cobalt} {CH}_{3} OH (l)
