When 9.42 g of methane (CH4) is burned in a bomb calorimeter (heat capacity = 2.677 × 103 J/°C), the temperature rises from 24.00 to 27.08°C.  Calculate the enthalpy change for the following reaction.  (C= 12.00 amu, H = 1.00 amu) 

                                                     CH4(g) + 2O2(g)  →  CO2(g) + 2H2O(l)

Group of answer choices
a. 8.425 kJ
b. –14.01 kJ
c. –8.425 kJ
d. 8245 J
