Enthalpy of Neutralization Reaction: A 25.0 mL sample of 0.200 M NaOH is mixed with a 25.0 mL sample of 0.200 M HNO3 in a coffee cup calorimeter. NaOH and HNO3 will undergo Neutralization Reaction according to the following balanced equation: NaOH(aq) + HNO3(aq) --> NaCl (aq) + H2O (l) Both solutions were initially at 35.00°C and Tmax of the resulting solution was recorded as 37.00°C (from the graph). Assume 1) that no heat is lost to the calorimeter or the surroundings, and...

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. Part A 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...
