Propane (C3H8) is a common gas used for generating flames for cooking and camping. It undergoes a combustion reaction with excess oxygen (O2) to yeld carbon dioxide (CO2), Water (H2O) and heat. Suppose that you only have 82g propane for your trip.
A) Write the balanced stoichiometric reaction for the combustion of propane.
B) For every molecule of CO2, what is the mass percentage of C?
C) Suppose that your torch has a fixed amount of oxygen at 50g. What is the limiting reagent for your reaction and how many mols of water are produced if this reactant is consumed completely?
D) How much of the excess reagent is remaning after burning up all of the limiting reagent above?
E) Based on the chemistry described above, explain why somethering a fire puts a flame out.
