Sucralose (the ingredient in Splenda) is a zero calorie artificial sweetener and sugar substitute that has been accepted as safe by the US Food and Drug Administration (FDA) and the European Union’s Scientific Committee on Food. Sucralose readily dissolves in water to form an aqueous solution. Sucralose has a chemical formula of C12H19Cl3O8 and a molar mass of 397.64 g/mol. Water has a chemical formula of H2O, a molar mass of 18.015 g/mol, and a density of 1.00 g/mL. If the mass of one “yellow packet” of Splenda, containing 12 mg sucralose, is dissolved in 8 oz of water (equivalent to 236.6 mL water), calculate the,Molarity (in units of millimolar or mM), Molality (in units of molality, or m), Masspercentage (in units of %), Parts per million (in units of ppm), andParts per billion (in units of ppb) of sucralose in the aqueous solution
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.
