###### Question:  Part A In the following experiment, a coffee-cup calorimeter containing 100 mL of H2O is used. The initial temperature of the calorimeter is 23.0 °C. If 3.10 g of CaCl2 is added to the calorimeter what will be the final temperature of the solution in the calorimeter? The heat of solution AHoln of CaCla is -82.8 kJ/mol Assume that the specific heat of the solution formed in the calorimeter is the same as that for pure water. C, 4.184 J/g C Express your answer with the appropriate units. View Available Hint(s) ? HA Value Units Submit
Review Constants I Periodic Table The addition of hydrobromic acid to a silver nitrate solution preciptates silver bromide according to the reaction AgBr(a) + HNO, (a) AgNOs (aq)+HBr(aq)- When 50.0 mL of 4.00-10 to 26.42 C M AgN0, is combined with 50.0 mL of 4.00-10 M HBr in a coffee-cup calorimeter, the temperature changes from 25.60 °C Part A Calculate AH. for the reaction as witten. Use 1.00 g/mL as the density of the solution and C, 4.18 J/(g"C) as the specific heat capacity of the solution Express the energy to two significant figures and include the appropriate units. Value Units AH
