Hydrates are ionic compounds that contain water molecules that are incorporated into the structure of the ionic compounds in a specific ratio. For example, barium chloride dihydrate has the chemical formula BaCl, 2H,O in which the two water molecules are incorporated into every unit of BaCl, ionic compound. In this experiment you will determine what are the final products that are obtained from heating of BaCl, 2H20. Depending on the extent of heating, three different sets of products are predicted as listed below: BaCl, 2H2O(s) heat BaCl, H2O(s) + H2O9) Reaction 1 2H2O(9) Reaction 2 BaCl, 2H,O(s) heat BaCl2(9) + BaO(s) + 2HCI (9) Reaction 3 BaCl, 2H,O(6) heat + H2O(g) QUESTION If the mass of BaCl, 2H2O6 sample subject to thermal decomposition was 2.526 g, what is the theoretical yield of BaOs) if Reaction 3 occurred. (The molar mass of BaCl2 2H2O, is 244.2 g; the molar mass of BaOs is 153.3 g) (s)

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.
