Unformatted text preview: klzxcvbnmqwer tyuiopasdfghjklzxcvbn Thermochemistry Sheldon Pope and Brandon Pezzuto 11/14/2007 Section 25 1a.) See graph attached labeled Change in Temperature for Salts. 1b.) The quantity of heat either absorbed or generated is increased when the mass of the salt is increased. So it is a direct correlation. 2a.) Eventually if you continue to add larger quantities of salt to the same amount of water, an increase or decrease in the change in temperature of the solution will occur depending upon the chemical composition of the salt. Eventually the salts will no longer be able to dissolve because of oversaturation and the temperature will remain constant. 2b.) As mass was increased heat was either generated or absorbed. As mass of the calcium chloride was increased, heat was generated. When mass of the Ammonium chloride and Sodium chloride was increased, heat was absorbed. 2c.) For calcium chloride as mass increased on the graph the change in temperature would increase and in ammonium chloride and sodium chloride as mass increased the...
