Consider the following chemical reaction:  

C6H6(l) + O2(g) --------------> CO2(g) + H2O(g) 

Calculate the change in internal energy of the reaction for 2.80 g C6H6(l). The temperature is 25oC.  

C=12.01 g/ mole and H = 1.008 g/mole 

delta H's :   C6H6(l) = -345 kJ/mole,   O2 = 0.00 kJ/mole,   CO2(g) =- 324 kJ/mole and H2O(g) = 215 kJ / mole
