# What coefficients would you use to balance this equation: N_2 + H_2 -> NH_3?

Nov 28, 2016

$\frac{1}{2} {N}_{2} \left(g\right) + \frac{3}{2} {H}_{2} \left(g\right) \rightarrow N {H}_{3} \left(g\right)$

#### Explanation:

Could you double the equation to remove the non-integral coefficients? How?

Why is this the most important reaction on the planet?

$1 {N}_{2} + 3 {H}_{2} \to 2 N {H}_{3}$
Since there are 2 N atoms on the left side of the equation, there must be 2 on the right, so multiply the $N {H}_{3}$ by 2. Then, since there are 6 H atoms on the right, there must be 6 on the left, so multiply the ${H}_{2}$ by 3 to get 6.
