Hello, can you please help with this chemistry exercise with your explanation? Thanks a lot for your help and your time! Aqueous solutions of: a) Cu(NO3)2 (aq) and KOH (aq) b) Ma2SO4(aq) and PbCl2(aq) c) CaCl2(aq) and K2CO3(aq) For each mixture: 1) determines the nature of the ions initially present in the solutions of the reagents 2) predict whether there may be the formation of a precipitate based on the qualitative solubility table and identify it 3) write where applicable the equations representing the precipitation reactions and identify the spectator ions
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.
