Which of the following products are formed on the hydrolysis of $NaO_2$?

Which of the following can reduce the decomposition of $H_2O_2$ on exposure to light?

The volume of oxygen liberated from $15 \, mL$ of $20$ volume $H_2O_2$ is ................ $mL$.

Electrolysis of $X$ gives $Y$ at anode. Vacuum distillation of $Y$ gives $H_2O_2$. The number of peroxy $(O-O)$ bonds present in $X$ and $Y$ respectively are :

On reaction with a stronger oxidizing agent like $KIO_{4}$,hydrogen peroxide is oxidized with the evolution of $O_{2}$. The oxidation number of $I$ in $KIO_{4}$ changes to $..........$

The dipole moment of $H_2O_2$ is more than that of $H_2O$,but $H_2O_2$ is not a good solvent because:
