After studylng the chemical reactions of many compounds made of carbon, August discovers a chemical bonds to other atoms when it forms a compound. that says carbon always forms 4 about the arrangement of elements In the Wolfgang develops a Periodic Table, based on some ideas about how electrons are arranged in the different atoms of different elements. Using equations he develops, he Is able to predict the exact arrangement of electrons in many atoms, and from there predict why they are where they are in the Periodic Table. Antoine burns some charcoal, and a very small diamond (!), and makes that the only product of both reactions is a heavy gas the (carbon dioxide).
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.
