In an experiment, 95.0 mL of 0.225 M silver nitrate was mixed rapidly with 47.5 mL of 0.225 M calcium chloride in a coffee cup calorimeter. If a reaction occurred, was it exothermic or endothermic? If the reaction started at 23.7 °C, what is the final temperature of the solution?

Answer 1

You don't provide enough information to answer this question. Look up the delta Ho formation and provide that data.

Answer 2

dHf=-99.4 kJ/mol (AgNO3)
dHf= -795.0 kJ/mol (CaCl2)
