    Isooctane, C8H18, is the component of gasoline from which the term octane derives.
    A) Write a balanced equation for the combustion of one mole of isooctane to yield CO2(g) and H2O(l).
    B) What is the volume (in liters) of CO2 at STP?
    C )The standard molar heat of combustion (delta Hrxn for the reaction is -5,456.6 kJ/mol. Calculate delta Hf for isooctane.
