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.

Constants Periodic Table Hydrates are solid compounds that contain water molecules. When hydrates are heated, the water molecules evaporate, producing the anhydrous form of the compound. The formula of a hydrate may be written in two different ways. For example, aluminum chloride hexahydrate can be written as (Al(H2O)6]Cl3 or as AlCls 6H2O. The first formula more accurately shows the bonding arrangement, whereas the second formula makes it easier to see that the anhydrous form of the compound is aluminum chloride. Part B IF 12.0 g of MgSO4 - 7H2O is thoroughly heated, what mass of anhydrous magnesium sulfate will remain?
