When 50.0mL of 1.20 M of HCl (aq)is combined with 50.0mL of 1.30 M of NaOH (aq) in a coffee-cup calorimeter, the temperature of the solution increases by 8.01 Degrees C. What is the change in enthalpy for this balanced reaction?

HCl(aq) + NaOH(aq) --yields-- NaCl(aq) + H20(l)

Assume that the solution density is 1.00 g/mL and the specific heat capacity of the solution is 4.18 J/ g x Degrees C
