Combustion of propane in the presence of oxygen yields carbon dioxide and water. The unbalanced equation is:
C3H8 (g) + O2 (g) image from custom entry tool CO2 (g) + H2O (g)
If 1.00 g of propane and 3.00 g of oxygen are reacted in a 1.00 L container at 227°C, determine
a) the limiting reactant.
b)the partial pressures of all gases and the total pressure, at the completion of the reaction.
c)the mass of excess reagent that will remain at the completion of the reaction
