CHEMWORK The production capacity for acrylonitrile (C3H3N) in the United States is over 2 billion pounds per year. Acrylonitrile, the building block for polyacrylonitrile fibers and a variety of plastics, is produced from gaseous propylene, ammonia, and oxygen: 2C3H6(g) + 2NH3(g) + 302(g) → 2C3H3N(g) + 6H₂O(g) Assuming 100% yield, determine the mass of acrylonitrile which can be produced from the mixture below: Mass 7.28×10² g 5.00 x 102 g 1.00 x 10³ g oxygen Reactant propylene ammonia Submit g= mass of acrylonitrile produced What mass of water is formed from your mixture? mass of water formed = g Calculate the mass (in grams) of each reactant after the reaction is complete: Reactant Mass remaining propylene ammonia oxygen Show Hints g 9 g Previous Next Save and

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.
