It appears you typed something wrong.
3 Pb(C2H3O2)4+ 4KH2PO4 -->Pb3(PO4)4 +4 CH3CO2K + 8HC2H3O2
by the way --- C2H3O2 andCH3CO2 are the same, just written in a different way. They are acetate ions with hydrogen it becomesacetic acid.
cl2o7+h2o
liho+h2s=
no
2 PbO + C -> 2 Pb + CO2
P + Na(OH) + H20 = NaH2PO2 + PH3
The balance is 2N2 +2O2= 4NO
2h2s + so2 ----------> 3s + 2h2o
cl2o7+h2o
4Li + O2 -> 2Li2O
2Al+3S--->Al2S3
Ca(SO3)
Already balanced
If you do a Trial Balance and your Credits Equal your Debits, then more than likely your books are correct.In double entry accounting the debits and credits must balance or be equal.
equilibrium
3h2 + n2 ==> 2nh3
It is already balanced
6AG + N2 --> 2AG3N is the balanced equation.
