iven the balanced chemical equation below, determine the mass of AgCl produced when 11g of Silver nitrate reacts with 15g of Sodium chloride. AgNO3 + NaCl --> AgCl + NaNO3 _________g AgCl How many grams of excess reactant remain after the reaction_________ g Blank 1: Blank 2: All work must be shown and submitted. Any steps left out may result in a loss of points for that particular problem.
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.
4.Given the balanced chemical equation below, determine the mass of AgCl produced when 11g of Silver nitrate reacts with 15g of Sodium chloride.
AgNO3 + NaCl --> AgCl + NaNO3
_________g AgCl
How many grams of excess reactant remain after the reaction_________ g
All work must be shown and submitted. Any steps left out may result in a loss of points for that particular problem.
