In a right pressure vessel, a mixture was prepared with only CH4 (g) and O2 (g). The mole fraction of the CH4 g was initially 0.50. A spark then initiated combustion to CO2 (g) and H2O (g). What is the mole fraction of CO2 (g) in the pressured vessel after combustion? Assume H2O remains in the gaseous phase.

Use the following atomic weights and quantities to calculate the theoretical yield of hydrogen gas, in liters, that should be given off by the reaction of phenylacetic acid, iron, and heat. Assume that at our elevation and laboratory temperature there are 22 liters per mole of an ideal gas. Balance the equation and remember that your yield must be based on the limiting reagent, and that grams must be converted to moles. Filling out most of the chart will help....
