easiest way to learn how to balance equations is by H2O

so we always have O2, never just O alone

and we can have H alone

so if we want to make water we get

H + O2 = H20

now there's a problem,
we have one H on the left but 2 on the right
and only 1 O on the right but we have 2 on the left

so here's where the balancing comes in.

here's what it should look like balanced:

4H + O2 = 2(H2O)

we multiplied the right by 2 so that the O becomes balanced
and we needed to multiply the H on the left by 4 because 2(H2) = H4
