Combustion of propane ${\mathrm{C}}_3{\mathrm{H}}_8+{\mathrm{O}}_2\to {\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O}$ for this reaction identify the co-effecients of reactants and products

Balanced chemical equation for combustion of propane is ${\mathrm{C}}_3{\mathrm{H}}_8+5{\mathrm{O}}_2\to 3{\mathrm{CO}}_2+4{\mathrm{H}}_2\mathrm{O}$
Hence, the co-efficient of reactants and products are 1, 5, 3 and 4.
