Question

the formula of magnesium oxide is MgO .state the formula of barium nitrate and barium sulphate ,if barium belongs to the same group as magnesium.

Answer 1

The group of Magnesium and barium is same.

So, the valency of barium is +2 and the valency of nitrate is -2.

So, the formula of barium nitrate of BaNO3.

On other hand the valency of the sulphate is -2, so the formula of the Barium sulphate is BaSO4.

Answer 2
