Jee-Yon Lee and Hee-Soo Yoo , Jong Sook Park , Kwang-Jin Hwang and Jin Seog KimJournal of Chemical Education2005 82 (2), 288In developing this laboratory, our initial motivation for the analysis of gases in a balloon was to answer simple and basic questions, such as, Why does a helium-charged balloon left in the air always drop in a few days? Is leakage of helium the only ...
A Methane Balloon Inflation Chamber

Curtis J. Czerwinski and Tanya J. Cordes , Joe FranekJournal of Chemical Education2005 82 (2), 248While several lecture demonstrations are possible using methane-filled balloons, it is often inconvenient to prepare these balloons since the pressure from standard laboratory and lecture hall gas nozzles is too low. As a solution to this problem, a ...

John Hanson and Tim HoytJournal of Chemical Education2002 79 (7), 845Introductory students design and carry-out experimental procedures to determine the identity of three unknown gases from a list of eight possibilities: air, nitrogen, oxygen, argon, carbon dioxide, helium, methane, and hydrogen. Although this is initially ...
