Consider that CuO(s) + H2SO4(aq) reacts to give CuSO4(aq) and CuO(s) + K2SO4 does not give a product. Which of the following statements explain why this is true? Group of answer choices CuO is not soluble in water and therefore cannot react with potassium sulfate to give a salt. Potassium sulfate cannot dissolve in water since it is a salt and cannot react with CuO. CuO is a basic salt and therefore reacts with sulfuric acid to give copper (II) sulfate and water. Acids and bases do not react with each other. CuO is very stable and therefore does not dissociate in water and therefore cannot react with the sulfate ion in potassium sulfate.
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.
