What are oxides ?
Write different types of oxides with one example each.

Explanation

Oxygen combines with a large number of metals and non-metals to form binary com-pounds. These binary compounds are called oxides.
Types of oxides :
(i) Acidic oxides : The oxides which combine with water to give an acid.
e.g., `CO_(2),B_(2)O_(3),N_(2)O_(5),SO_(2),SO_(3),Cl_(2)O_(7)`
(iii) Basic oxides : The oxides which combine with water to form a base.
e.g., `CaO, Na_(2)O, K_(2)O, MgO`.
(iii) Amphoteric oxides : The oxides which show both acidic and basic characteristics.
e.g., `Al_(2)O_(3),SiO_(2),ZnO,PbO, SnO.`
