Solution: The addition of hydrochloric acid to a silver nitrate solution precipitates silver chloride according to the reaction:AgNO3(aq) + HCl(aq) → AgCl(s) + HNO3(aq)When 50.0 mL of 0.100 M AgNO3 is combined

Problem

The addition of hydrochloric acid to a silver nitrate solution precipitates silver chloride according to the reaction:

AgNO3(aq) + HCl(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 ΔHrxn for the reaction as written. Use 1.00 g/mL as the density of the solution and Cs = 4.18 J/(g • ˚C) as the specific heat capacity of the solution.
