Which one of the following reactions does not form gaseous product?

Options

A $\mathrm{PbO}_2+\mathrm{H}_2 \mathrm{O}_2 \rightarrow$
BAcidified $\mathrm{KMnO}_4+\mathrm{H}_2 \mathrm{O}_2 \rightarrow$
C $\mathrm{PbS}+\mathrm{H}_2 \mathrm{O}_2 \rightarrow$
D $\mathrm{Cl}_2+\mathrm{H}_2 \mathrm{O}_2 \rightarrow$

Correct answer

C. $\mathrm{PbS}+\mathrm{H}_2 \mathrm{O}_2 \rightarrow$

Step-by-step solution

Hydrogen peroxide oxidise lead sulphide into lead sulphate which is a solid.

\mathrm{PbS}+4 \mathrm{H}_2 \mathrm{O}_2 \longrightarrow \mathrm{PbSO}_4+4 \mathrm{H}_2 \mathrm{O}
