Question

Calculate the heats of combustion, in frac{kJ}{mol}, for the following reactions from the standard enthalpies of formation. Note: Reference the Thermodynamic properties of pure substances table for additional information. Part 1 of 2 Be sure your answer has the correct number of significant digits. 2H$_2$(g) + O$_2$(g) $ ightarrow$ 2H$_2$O(l) Part 2 of 2 Be sure your answer has the correct number of significant digits. C$_2$H$_5$OH(l) + 3O$_2$(g) $ ightarrow$ 2CO$_2$(g) + 3H$_2$O(l)
