In a coffee-cup calorimeter, 50.0 mL of 0.100 M AgNO3 and 50.0 mL of 0.100 M HCl are mixed. The two solutions were initially at 22.60°C, and the final temperature is 23.40°C. Assume that the specific heat and density of the solution after mixing is the same as that of water.

a. Is this reaction exothermic or endothermic?

b. Write a balanced reaction for this experiment. Make sure that you put in the states of each reactant and product.

c. Calculate ΔHrxn for the reaction (as given in the experiment) in Joules.

d. What is ΔHrxn for the reaction in Joules per mole of silver nitrate?
