its balanced
Co2 + 3h2 gives ch3oh + h2o
As with any combustion reaction you need to include oxygen. The full equation for methanol combustion is: CH3OH + 2 O2 --> CO2 + 2 H2O
2h2s+o2-->2h2o+co2
C3h8 + 5o2 --> 3co2 + 4h2o
Ag+Ba yields no reaction.
2KClO3 --> 2KCl + 3O2
N2O5 + H2O = 2 HNO3
You mean balance it? 2C2H6 + 7O2 -> 4CO2 + 6H2O
NO. There is no chlorine on the reactant side, so it cannot be balanced.
2HgO(heat) ----> 2Hg + O2
Fe + S = FeS
S + o2 --> so2
