Heat in Combustion

  1. Jul 4, 2009 #1
    How much heat, in kilojoules, is evolved in the complete combustion of 1.325 g C4H10(g) at 23.6 degrees Celsius and 738 mmHg? The complete combustion of butane is represented by this equation

    C4H10(g) + [tex]\frac{13}{2}[/tex] O2(g)[tex]\rightarrow[/tex] 4CO2(g) + 5H2O(l)
    [tex]\Delta[/tex]H degrees Celsius = -2877 kJ

    I am not sure at all how to do this and this is something we went over very briefly in class without any examples, so any help would be greatly appreciated.

    You were given the heat of enthalpy of...?

    What does the heat of enthalpy mean anyway?

    How much butane do you have to start with?
