Solution

(a) Those metal oxides which show basic, as well as acidic behavior, are known as amphoteric oxides.
Example: aluminium oxide and zinc oxide

(b) Acidic oxide are $C O_{2}, C O, S O_{2}$ and $N_{2} O .$
Basic oxide are $N a_{2} O$ and $M g O .$
Neutral oxide is $H_{2} O .$

(c) Amphoteric oxides are $Z n O$ and $A l_{2} O_{3} .$
