# How do you balance H2+O2-->H2O?

Mar 4, 2018

$2 {H}_{2} + {O}_{2} \rightarrow 2 {H}_{2} O$
With ${O}_{2}$ on the left side the right side will need to have an even multiple of ${H}_{2} O$ to balance the oxygen.
The simplest way to to have 4 times a multiple of hydrogen from the let side using ${H}_{2}$ is with $2 {H}_{2}$
