75.0g ammonia NH3 reacts with 197.0 g fluorine to produce dinitrogen tetrafluoride and hydrogen fluoride (used in production of aluminum, in uranium processing, and in frosting of light bulbs) according to the unbalanced equation below. NH3(g) + F2(g) → N2F4(g) + HF(g) Answer all the following questions, show all the work and calculations. Pay attention to significant figures: Balance the equation above using smallest set of whole numbers. Given the mass of ammonia above, how many moles of ammonia reacts with fluorine? Given the mass of fluorine, how many moles of fluorine reacts with ammonia?
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.
