Two solutions, initially at 24.60 Degrees Celsius are mixed in a coffee cup calorimeter. When a 100.0 mL volume of 0.100M AgNO3 solution is mixed with a 100.0 mL sample of 0.200 M NaCl solution, the temperature in the calorimeter roses to 25.30 degrees Celsius. Determine the  triangle H  degree rxn for the reaction as written below. Assume that the density and heat capacity of the solutions is the same as that of water. The specific heat Capacity of water = 4.18 j/g degrees Celsius NaCl (aq) + AgNO3(aq) —> AgCl (s) + NaNO3  triangle H degree rxn ?
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
