Question

Gas Grill Reaction The burner in a gas grill mixes 24. 0 volumes of air for every one volume of propane (C3H8) fuel. Is the flame produced by the burner: fuel-rich (excess propane in the reaction mixture), fuel-lean (not enough propane), or stoichiometric (just right)? Given: like all gases, the volume that propane occupies is directly proportional to the number of moles of it at a given temperature and pressure. Air is 21. 0% (by volume) O2. How many moles of propane are needed to completely use up the oxygen in 24. 0 moles of air?

Explanation / Answer

16 stoichiometric
