Sodium chloride, the table salt (NaCl) is added in cooking to enhance the flavor of the food.  When 10.0 g of NaCl are added in 200.0 mL of water at 25.0oC in a coffee-cup calorimeter, 669 J of heat are absorbed.  (Assume that there is no change in volume, d=1.00 g/mL, specific heat=4.18 J/g.oC). Evaluate the truthfulness of this statement: "Based on the above description, the solution process (i.e., the dissolution of NaCl or the breakdown of NaCl into its constituent ions) is exothermic."  True  False
