The oxide of a metalhas the formula mo what will
be the formula of sulphateand nitrite

​

Answer 1

Answer:

The formula  will be↡

Explanation:

Chemical formula‎: ‎NO−; 2...☆*: .｡. o(≧▽≦)o .｡.:*☆

Answer 2

Answer:

mSO4, m(NO2)2

Explanation:

Valency of oxide anion= -2

Therefore, to form a metallic oxide with formula mo, where m is the metal, valency of metal should also be = +2.

Valency of m = +2

1. Valency of sulphate ion = -2, formula = (SO4)2-

or, the formula of metallic sulphate = mSO4

2. Valency  of nitrite ion = -1, formula = (NO2)-

or, the formula of metallic nitrite = m(NO2)2
