Calculate the percent composition of caf2?

  1. Once water starts to boil, the temperature remains constant until the boiling process is complete, even though heat energy is still being added. What is this heat energy being used to do during this time?
  2. If a fixed amount of gas is in a rigid container and the temperature drops, what happens to the pressure in the container? Is this relationship directly proportional or inversely proportional?
  3. Determine the pH of a solution that has an [H+] concentration of 5.4 x 10-4m  . Is this substance acidic, basic, or neutral? Explain how you determined if it was acidic, basic, or neutral.
  4. For the following redox reaction, state the oxidation number for each element in the reaction. Then state which element is being oxidized and which element is being reduced. 2h2 + O2 --> 2h2o
