... In a coffee cup calorimeter, 50.0 mL of 0.100 M silver nitrate and 50.0 mL of 0.100 M HCl are mixed. The following reaction occurs: Ag+ (aq) + Cl- (aq) AgCl (s). If the two solutions are initially at 22.60 oC, and if the final temperature is 23.40 oC, calculate the change in enthalpy for the react ...
