A 35.987 g silver cube is heated to 99.5 °C and placed into a beaker containing 100.0 g of water. If initial temperature of the water is 19.8 °C, what is the final temperature of the water and silver cube? The specific heat capacity of the silver is 0..235 J/g.°C, and the specific heat capacity of water is 4.18 J/g.°C. Submit your answer below and submit your work for complete credit.
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.
