Rewrite and Balance the Equation
N₂ + H₂ -> NH3

N

2

+ 3

H

2

> 2N

H

3

Explanation:

N

2

+

H

2

> N

H

3

Let us balance this equation by counting the number of atoms on both sides of the arrow.

N

2

+

H

2

> N

H

3

N=2 , H=2 N=1, H=3

To balance the number of N atom on Right Hand Side (RHS) , I will add one molecule of N

H

3

on RHS

N

2

+

H

2

> 2N

H

3

N=2 , H=2 N=2 , H= 6

To balance the number of H atoms on Left Hand Side (LHS) , I will add two molecules of

H

2

on LHS

N

2

+ 3

H

2

> 2N

H

3

N=2 , H=6 N=2 , H= 6
