Bruce Mattson and Michael Anderson, Dept. of Chemistry, Creighton University, Omaha, Nebraska 68178 USA, Susan Mattson, Underwood High School, Underwood, Iowa 51576 USAAbstract:
This workshop is intended for those who have completed the Introductory Workshop (at ChemEd 2001 or earlier) or have experience with gas-generation in large syringes (from the series in Chem13 News, for example). Learn to safely and conveniently generate HCl, CO, C2H4, CH4, N2O, and SiH4. Generation of and experimentation with most of these gases is suitable for highschool and college teachers and their students. Generation of and experimentation with SiH4 is suited for demonstration use. Participants will also work with a glass-encased hetereogenous palladium catalyst tube (available for $20) suitable for demonstrating gas phase reactions in the classroom or teaching laboratory. The catalyst tube can be used to demonstrate a wide variety of reactions including oxidation of methane with air, oxidation of ethene with air, oxidation of carbon monoxide with air, hydrogenation of ethene, oxidation of ammonia with oxygen, oxidation of methane and nitrogen dioxide, oxidation of methane and dinitrogen monoxide, reaction between hydrogen and nitrogen monoxide, as well as others. During this workshop participants will receive a gas generation kit.
