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 you combine 50.0 ml of 0.100 m agno3 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 c = 4.18 j/g ∙ °c as the specific heat capacity.
