MNO3 is athe formula for nitrate of a metal.Write down the formula for:-

1. Oxide of M
2. Nitride of M
3. Sulphate of M
4. Carbonateof M
5. Hydroxide of M

Nitrate ion has a valency of 1 and combines in the ratio 1:1 with metal M. So, metal has a valency of 1 and charge  of 1+.

Oxide has charge 2-, so  formula is M₂O
Nitride  has charge 3-, so formula is M₃N
​Sulphate has charge 2-, so formula is M₂SO₄
​Carbonate has charge 2-, formula is M₂CO₃
Hydroxide has charge 1-, formula is MOH
