1 Recitation Activity 5 (Chem 121) Chapter 5 1. If you went to a football game with a thermos of tea and a thermos containing the same mass of potato soup, heated to the same initial temperature, which would cool faster and why? Nearly everything in a condensed phase has a heat capacity less than water. (Hint#1: The potato soup has a large proportion of starch and fat which have much lower specific heats than that of water. Hint#2: The greater the heat capacity of a substance, the greater the heat required to produce a given rise in temperature. The heat capacity for 1 gram of a substance is called the specific heat (C s ). C s = q/(m x ?T)) [ONLY SPEND A MAXIMUM OF 10 MINUTES ON THIS PROBLEM] 2. Sodium chlorite is used in some bleaching agents due to its ability to oxidize organic compounds. Write a balanced equation to represent the oxidation-reduction reaction for the reaction between sodium chlorite and glucose (C 6 H 12 O 6 ) to form sodium chloride, carbon dioxide and liquid water.
