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? hcl(aq) + naoh(aq) → nacl(aq) + h2o(l) assume that the solution density is 1.00 g/ml and the specific heat capacity of the solution is 4.18 j/g⋅°c.
