Consider a piece of cushioned furniture to be primarily polyurethane foam. The nominal chemical formula of the foam is CH1.74O0.323N0.07. Calculate the stoichiometric fuel-to-air ratio, the maximum yields of CO2 and H2O. For complete combustion of the fuel to CO2 and H2O, the following chemical equation can be written as: CH1.74O0.323N0.07+1.2735(O2+3.76N2)1.0CO2+0.87H2O+4.823N2
