Solution

Two oxides are anhydrides of dibasic oxy-acid.
$S O_{2}$ is anhydride of dibasic oxyacid $H_{2} S O_{3} .$
$P_{4} O_{10}$ is anhydride of monobasic oxyacid $H P O_{3} .$

$N O_{2}$ is mixed anhydride of monobasic oxyacids $H N O_{2}$ and $H N O_{3} .$

$C O_{2}$ is anhydride of dibasic oxyacid $H_{2} C O_{3}$ .

$L i_{2} O$ is anhydride of base $L i O H$ .

$C O$ is not anhydride of dibasic oxyacid.

$C l O_{2}$ is mixed anhydride of monobasic oxyacid $H C l O_{2}$ and $H C l O_{3}$ .

$C l_{2} O$ is anhydride of monobasic oxyacid $H C l O$ .

$I_{2} O_{5}$ is anhydride of monobasic oxyacid $H I O_{3}$ .
