Hydrogen peroxide $(H_2O_2)$ is:

How many $mL$ of perhydrol is required to produce sufficient oxygen which can be used to completely convert $2 \ L$ of $SO_2$ gas to $SO_3$ gas (in $mL$)?

What is the gas liberated when alkaline formaldehyde solution is treated with $H_2 O_2$?

Which statement is false about $H_2O_2$?

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 $..........$

$(i)$ Draw the gas phase and solid phase structure of $H_2O_2$.
$(ii)$ $H_2O_2$ is a better oxidizing agent than water. Explain.
