How many grams of oxygen do you need to burn 1 lb (454 g) of fat? Enter only a numerical answer, do not enter units. Note: for the molar mass of fat, use the chemical formula of an average triglyceride C55H10406 To calculate the mass of oxygen you MUST USE STOICHIOMETRY (convert mass of fat into moles, then mol of fat into mol of O₂, then mol of O2 into mass of O2); do not use a simple proportion derived by the approximate data in the video.
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.
