Match List $I$ with List $II$ and select the correct answer using the codes given below the lists:

$A$. Peroxide	$1$. $C_3O_2$
$B$. Superoxide	$2$. $PbO_2$
$C$. Dioxide	$3$. $KO_2$
$D$. Suboxide	$4$. $H_2O_2$

The $H-O-O$ bond angle in $H_2O_2$ is ............. $^o$

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)

$10 \, mL$ of $H_2O_2$ solution $(d = 1 \, g/mL)$ when reacted with $KI$ solution produced $0.5 \, g$ of iodine. Calculate the percentage purity of $H_2O_2$ .............. $\%$
