When 50.0 mL of 1.27 M of HCl(aq) is combined with 50.0 mL of 1.32 M of NaOH(aq) in a coffee-cup calorimeter, the temperature of the solution increases by 8°C. What is the change in enthalpy for this balanced reaction? Assume that the solution density is 1.00 g/mL and the specific heat capacity of the solution is 4.18 J/g⋅°C. HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
