Hot air balloons rise when atmospheric gases are heated, typically by burning propane, and the density of the gases decreases. While you are watching one of these balloons rise, a large rip appears. Which of the following atmospheric gases present will be the first to escape? Argon (Ar), Carbon dioxide (CO2), Nitrogen (N2), or Oxygen (O2) ? State you answer, then briefly explain why you chose your answer.

1. Two compounds have the same Rf (0.87) under identical conditions. Does this show that they have identical structures? Why or why not? If not, what additional experiments would you perform? 2. Why can there be no breaks in the thin-layer surface of a TLC plate? 5. Write out the reaction between an organometallic reagent and acetone and use that to explain why these reactions must be kept dry (H20) and free of acetone.
