Question

MNO3 is athe formula for nitrate of a metal.Write down the formula for:- Oxide of M Nitride of M Sulphate of M Carbonateof M Hydroxide of M

Answer 1

MNO3 is formula for M's nitrate therefore its valency is 3. So oxide of M will be M2O3 Nitride of M will be MN3 Sulphate of M will be M2 (SO4)3 Carbonate of M will be M(CO3)3 Hydroxide of M will be M (OH)3

Answer 2

Valency of M is 1.
Formula of M Nitride = M3N
M Sulphate = M2SO4
M Carbonate = M2CO3
M Oxide = M2O
M Hydroxide = MOH
