Problem 13.015 Propane (C3H8) burns completely with 150% of theoretical air entering at 74°F, 1 atm, 50% relative humidity. The dry air component can be modeled as 21% O2 and 79% N2 on a molar basis. The combustion products leave at 1 atm. For complete combustion of propane(C3H8) with the theoretical amount of air, what is the number of moles of oxygen (O2) per mole of fuel?
7. Propane is burned in air according to the chemical equation: C3H8(g) + 5 O2(g) ® 3 CO2(g) + 4 H2O(g) If you burn 455g of propane in air, a. How many moles of oxygen is required? ____________________ b. How many moles of CO2 would be produced? ____________________ c. How many moles of H2O would be produced?____________________ d. Why aren't the moles of CO2 and H2O not the same?
3. A rich fuel-air ratio of propane in burned in an internal combustion engine. The analysis exhaust gas by the exhaust analyzer shows that CO2 = 17%, C3H8=0.5%, with the rest being N2 and some traces of H20. For this case Calculate: a) Write the balanced chemical equation for propane b) Compute air-fuel ratio and equivalence ratio when the ideal AFR is 14.8 ran
(25)4. Consider thefollowing reaction representing the combustion of butane: C3H8 O2 CO2+ H20 (a) (b) (c) Balance the equation. How many moles of oxygen are required to burn 1 mole of propane? How many grams of oxygen are required to burn 1 kg of propane? to burn 1 kg of propane? If air is21 percent oxygen, what volume of air at STP would be required? burned?
