Answer 1

Answer with explanation:

A molecular formula is a type of chemical formula which shows the number and type of atoms present in a molecule.

From the given information, we are to deduce the molecular formulas of the compounds that can be formed with the given pairs of elements.

(i) H (valency) and O (valency 2):

H_2OH2O - Water

(ii) N (valency) and H (valency 1) :

NH_3NH3 - Ammonia

(iii) Fe (valency) and S (valency 2):

Fe_2O_3Fe2O3 - Iron (III) Oxide
