A fuel oil is analyzed and found to contain 83.86 wt\% carbon, 13.40% elemental hydrogen (H),1.90% sulfur, and the remainder noncombustible matter. The oil is burned with 7.5% excess air, based on complete combustion of the carbon to CO2, the hydrogen to H2O, and the sulfur to SO2. The oil is burned completely, but 6.50% of the carbon forms CO. Calculate the molar composition of the stack gas. You may take the composition of air to be 79.0 mole\% N2 and 21.0 mole\% O2. yN2= yO2= yH2O= yCO= yCO2= ySO2=
