Question

Write steps for balancing chemical equation for formationof ammonia

Answer 1

Explanation:

N2+ H2 _________NH3(Unbalanced equation).

(i)

Examine the number of atoms of different elements present in the

unbalanced equation.

(ii)In the above reaction both the sides N2 and H2 both are unbalanced.

(iii)

To balance hydrogen, H2 is

multiplied by 3. It makes 6H-atoms on the left hand side.

(iv)

Now to balance hydrogen atoms on the right hand side NH3 should be multiplied by 2. It make 61-1-atoms on this side.

(v)

Now to balance nitrogen atoms, they are counted separately for both the

sides and we will find that, nitrogen atoms are 2 on both left hand side and right hand side.

(vi)

Balanced chemical equation will be :

N2 + 3H2—■ 2NH3
