The addition of hydroiodic acid to a silver nitrate solution precipitates silver iodide according to the reaction: agno3(aq)+hi(aq)→agi(s)+hno3(aq) when 50.0 ml of 5.00×10−2m agno3 is combined with 50.0 ml of 5.00×10−2m hi in a coffee-cup calorimeter, the temperature changes from 22.40 ∘c to 22.91∘c. calculate δhrxn for the reaction as written. use 1.00 g/ml as the density of the solution and cs=4.18j/(g⋅∘c) as the specific heat capacity of the solution. express the energy to two significant figures and include the appropriate units
