14) Propane, C3H8, is a hydrocarbon that is commonly used as fuel for cooking.
a) Write a balanced equation for the complete combustion of propane gas, which yields CO2(g) and
H2O(l).
b) If 10.0 g of propane undergo combustion, how many moles of oxygen will be consumed?
c) Assuming that air is 21.0 percent O2 by volume, calculate the volume of air needed to completely
combust 10.0 g of propane at 30oC and 1 atm
d) If the combustion of propane produces 2220 kJ/mole, how much energy is produced when 30.0 g
of propane undergoes complete combustion?
e) If the process described in d) above occurs in a calorimeter containing 8.25 kg of water, calculate
the change in temperature of the water that would be observed.
