Balancing Equations Chemistry Example 4

Solution

1. 1
   Balance nitrogen first: there are 2 N atoms on the left, so put a 2 in front of $$\text{NH}_3$$.
2. 2
   Now there are 6 H atoms on the right, so put a 3 in front of $$\text{H}_2$$. The balanced equation is $$\text{N}_2 + 3\text{H}_2 \rightarrow 2\text{NH}_3$$.
