In the Gizmos, you did some problems in Activity B using this balanced equation. Fe2O3 + 3CO yields 2Fe + 3C02 What volume of CO2 can be produced if 72.25 g Fe is also produced? Get your starting place (given unit) and ending place (answer unit) then determine the conversions necessary to go from one place to the next with all of your units cancelling. Answer to 2 sig figs and your unit will be L CO2
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.
