The chlorofluorocarbon CCl2F2 was once used in air conditioners as the heat transfer fluid. Its normal boiling point is
-30 °C, and its enthalpy of vaporization is 165 J g-1. The gas and the liquid have specific heat capacities of 0.61 J g-1
 °C-1 and 0.97 J g-1 °C-1, respectively. How much heat is evolved when 10.0 g CCl2F2 is cooled from 40 °C to -40 °C?
A reaction is begun with a reaction mixture containing the following: [dye] = 1.0 x 10-4 M [bleach] = 0.10 M When [dye] = 8.0 x 10-5 M the rate is determined to be 3.74 x 10-7 M/min. When [dye] = 4.0 x 10-5 M the rate is determined to be 1.71 10-7..
How much CH4, in grams, is needed to produce 50.0 grams of CHCl3?
a 5.00L air sample at a temperature of -50 degrees celsius has a pressure of 107 kpa. what will be the new pressure if the temperature is raised to 102 degrees celsius and the volume expands to 7.00L.
what is the entropy of a mixture made of 2.4 moles of O2 and 9.2 moles of N2 at the same temperature and pressure?
A solvent for an industrial process requires the use of phenol or benzene. Both are about the same in effectiveness for the process, and of course, gloves will be used when handling either solvent
