A 100.mL sample of 0.200 M aqueous hydrochloric acid is added to 100.mL of 0.200 M aqueous ammonia in a calorimeter whose heat capacity excluding any water is 480.J/K. The subsequent reaction occurs when the two solutions are mixed.
HCl(aq) + NH3(aq)->NH4Cl(aq)
The temperature increase is 2.34 degrees Celsius.
Compute delta H per mole of HCl and NH3
