#N_2+3H_2→2NH_3#

#N_2+H_2→NH_3#

As written, there are #2# #N# atoms on the left and #1# on the right, while there are #2# #H# atoms on the left and #3# on the right.

Add a coefficient of 2 on the right:

#N_2+H_2→2NH_3#

Now there are #2# #N# atoms on both sides, but #2# #H# on the left and #6# on the right. Add a coefficient of #3# in front of the #H_2#.

#N_2+3H_2→2NH_3#

This is now a balanced equation.
