Question

Problem 11a

Answer 1

Given information

Molecular formula is prepared by balancing the valencies of the constituents.

Valency of anion and cation are neutralized to obtain the molecular compound.

Step-by-step explanation

Step 1.

Here, for the formation of a molecular compound, the valency of both elements is counted.

Here, symbol and charge of magnesium =    

and, symbol and charge of sulfur =    

Adjusting the subscript on each cation and anion, we get  .
