Two solutions initially at 24.60°C are mixed in a coffee cup calorimeter. when a 100.0 ml volume of 0.100 m AgNO3 solution is mixed with a 100.0 ml sample of 0.200 m nacl solution, the temperature in the calorimeter rises to 25.30°C. Determine the dh for the reaction as written below. Assume that the density and heat capacity of the solutions is the same as that of water.
NaCl(aq)+AgNO3(aq) → AgCl(s)+NaNO3(aq)
a. -69 kJ
b. -35 kJ
c. -16 kJ
d. -250 kJ
