Which of the following metals will not reduce $H_2O_2$?

How does $H_2O_2$ behave as a bleaching agent?

$A$ colourless liquid $A$ contains $H$ and $O$ elements only. It decomposes slowly on exposure to light. It is stabilised by mixing urea to store in the presence of light.
$(i)$ Suggest the possible structure of $A$.
$(ii)$ Write the chemical equation for its decomposition reaction in light.

The volume strength of $8.9 \, M \, H_{2}O_{2}$ solution calculated at $273 \, K$ and $1 \, atm$ is.........
$(R = 0.0821 \, L \, atm \, K^{-1} \, mol^{-1})$ (rounded off to the nearest integer)

Which one of the following reactions represents the oxidising property of $H_2O_2$?

Which of the following is $NOT$ true for the electrolytic preparation of $H_2O_2$?
