Solution

The unbalanced chemical equation for the reaction of nitrogen and hydrogen to produce ammonia is:

N2 + H2 --> NH3

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

Step 1: Balance the nitrogen atoms. There are 2 nitrogen atoms on the left side of the equation and only 1 on the right side. To balance the nitrogen atoms, we put a coefficient of 2 in front of NH3:

N2 + H2 --> 2NH3

Step 2: Balance the hydrogen atoms. Now there are 2 hydrogen atoms on the left side of the equation and 6 on the right side (since there are 2 NH3 molecules, each with 3 hydrogen atoms). To balance the hydrogen atoms, we put a coefficient of 3 in front of H2:

N2 + 3H2 --> 2NH3

The balanced chemical equation is:

N2(g) + 3H2(g) --> 2NH3(g)

This indicates that one molecule of nitrogen gas reacts with three molecules of hydrogen gas to produce two molecules of ammonia gas.
