has 2 oxygens for every carbon.
will contribute one of each for every molecule. You then have to have an even multiple of
molecules to not end up with an odd number of oxygens.
So if you take
, you should end up with 2 carbons on the RHS.
then has 4 oxygens. 2 of them are already accounted for, so you just need one
to balance out the reaction.
not to buy all of them they can by 55 boxs
