The literature value of Ksp is not well known. Your textbook reports a value of 2.9 x 10-8 in Chapter 16 and the Handbook of Chemistry and Physics reports a value of 4.43 x 10-10. Typical values in this class are different from both of these. What are the experimental uncertainties and assumptions you made that might lead to a different amount of solubility for copper oxalate? Where possible, suggest possible experiments to check these issues. (The description of possible experiments does not need to be detailed - describing a possible experiment in a sentence or two should suffice.)
Chlorine gas can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid. How much MnO2 should be reacted with excess HCl to obtain 275 mL of chlorine gas at 5.0 °C and 650 mmHg?
the ternary compounds called chlorofluorocarbons, or Freons, have proved to be very valuable as refrigerants and as cleaning agents for circuit boards. Unfortunately, in the atmosphere these compounds produce chlorine atoms that catalyze the decom..

A 2.52- sample of a compound containing only carbon, hydrogen, nitrogen, oxygen, and sulfur was burned in excess to yield 4.36 of and 0.892 of as the only carbon and hydrogen containing products respectively.
One way to experimentally measure the heat capacity of a Styrofoam cup calorimeter would be to melt a known mass of ice in warm water and measure the temperature change. Use the data below to determine the experimental heat capacity of a calorimet..
