## (i) Hydrogen + Chlorine → Hydrogen chloride

(i) Hydrogen + Chlorine → Hydrogen chloride

The skeletal chemical equation of the above reaction is

H 2 + Cl →  HCl

 Element Name No of Atoms in Reactant No of Atoms in Product Hydrogen 2 1 Chlorine 1 1

1. Number of atoms of Hydrogen in reactants number of atoms of Hydrogen in products

To balance number of Hydrogen,

We multiply the products by 2

The chemical equation becomes

H 2 + Cl →  2 HCl

 Element Name No of Atoms in Reactant No of Atoms in Product Hydrogen 2 2 Chlorine 1 2

1. Now,

Number of atoms of Hydrogen in reactants = number of atoms of Hydrogen in products

But, Number of atoms of Chlorine in reactants number of atoms of Chlorine in products

To balance number of Chlorine,

We multiply the Cl atom in reactants by 2

The chemical equation becomes

H 2 + 2 Cl →  2 HCl

Now,

 Element Name No of Atoms in Reactant No of Atoms in Product Hydrogen 2 2 Chlorine 2 2

Now, all the elements are balanced and the balanced equation is

H 2 + 2 Cl →  2 HCl

H 2 + 2 Cl →  2 HCl
