Part A
The addition of hydrochloric acid to a silver nitrate solution precipitates silver chloride according to the reaction:
AGNO3 (aq) + HCI(aq) → AgCl(s) + HNO3(aq)
When 50.0 mL of 0.100 M AGNO3 is combined with 50.0 mL of 0.100 M HCl in a coffee-cup calorimeter, the
temperature changes from 23.40 °C to 24.21 °C. Calculate AHxn for the reaction as written. Use 1.00 g/mL as
the density of the solution and C = 4.18 J/(g °C) as the specific heat capacity.
