Explanation / Answer

the given recation is a combustion reaction in which propane gas( C3H8) is decomposed in presence of oxygen.decomposed propane combine with oxygen to form CO2 and water vapour( H2O).

C3H8+ O2= CO2+H2O

to follow the law of mass of convertion, the mass of reactants is equal to mass of products, then the balanced equation wil be C3H8+5O2= 3CO2+ 4H2O
