We can think of a bond or a lone pair of electrons as a "domain" of electrons. Single bonds, double bonds, and triple bonds each count as one domain. How do the electrons in bonds (bonding domains) differ from lone pairs (non-bonding domains)? What happens to the bond angle when you add or remove an electron domain? Can you force the atoms into new configurations by pushing atoms around? What does this suggest about the configuration of atoms in real molecules? What is the difference between Electron Geometry and Molecule Geometry? In one or two grammatically correct sentences, write a definition for the term Molecule Geometry.
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.
