LAB 8 Pre-Lab Questions portions of lab adapted from various online and reference sources 1. Fill in the missing parts of this chemical equation. Remember that a chemical with a dot in the middle is called a hydrate. The arrow means that heat will be applied, which will drive off the water from the hydrate. No physical states needed, but your final answer should be balanced. CuSO4.5H₂O -> CUSO4 + 2. Calculate the molar mass of the hydrate ZnSO4.7H₂O.
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.
