Answer:
formula of nitride = M₃N₂
formula of bicarbonate = M(HCO₃)₂
Explanation:
here, If the metal forms oxide MO then its valency is 2.
∵ nitride valency is -3
so, by criss cross method
M N
2 3
∴ formula = M₃N₂
now, valency of bicarbonate is -1
so, by criss cross method
M HCO₃
2 1
∴ formula = M(HCO₃)₂
