Answer the following questions about diethyl ether (C4H10O, molar mass of 74.1 g/mol), the first widely used general anesthetic. Diethyl ether can be prepared from ethanol according to the following balanced equation. a. How many moles of diethyl ether are formed from 2 mol of ethanol? mol diethyl ether b. How many moles of water are formed from 6 mol of ethanol? mol water
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.
