Answer:
Balance the equation N2 + H2 ⇒ NH3
Balancing chemical equations is usually easier than it looks
There are 2 Nitrogens and 2 Hydrogens on the left side
There are 1 Nitrogen and 3 Hydrogens on the right side
Hydrogen seems to be the more complicated term so we should start with that
_N2 + _H2 ⇒ _NH3
With 2 H on one side and 3 on the other, our common multiple is 6
To balance the H we need to multiply H2 by 3 and NH3 by 2
_N2 + 3H2 ⇒ 2NH3
Now that we have H balanced, we need to look at N
There are 2 Nitrogens on both sides of the equation, so in this case, it is done
