Gases : IDGasFromVelocity (8 Variations)
The following are graphs of molecular velocities versus the relative number of molecules for argon, chlorine, methane and xenon at 300K. Which graph is for argon?
Exploring Solid-State Structure and Physical Properties: A Molecular and Crystal Model ExerciseThomas H. Bindel This laboratory allows students to examine relationships among the microscopicmacroscopicsymbolic levels using crystalline mineral samples and corresponding crystal models. The exercise also reinforces Lewis dot structures, VSEPR theory, and the identification of molecular and coordination geometries. Bindel, Thomas H. J. Chem. Educ.2008, 85, 822.

Predicting the Stability of Hypervalent MoleculesTracy A. Mitchell, Debbie Finocchio, and Jeremy Kua In this exercise, students use concepts in thermochemistry such as bond energy, ionization potentials, and electron affinities to predict the relative stability of two hypervalent molecules (PF5 and PH5) relative to their respective non-hypervalent counterparts. Mitchell, Tracy A.; Finocchio, Debbie; Kua, Jeremy. J. Chem. Educ.2007, 84, 629.

Let Us Give Lewis Acid–Base Theory the Priority It DeservesAlan A. Shaffer The Lewis concept is simple yet powerful in its scope, and can be used to help beginning students understand reaction mechanisms more fully. However, traditional approaches to acid-base reactions at the introductory level ignores Lewis acid-base theory completely, focusing instead on proton transfer described by the Br?nsted-Lowry concept. Shaffer, Alan A. J. Chem. Educ.2006, 83, 1746.

Organic XenobioticsWilliam F. Coleman The molecules for this month come from the article, Intermolecular Forces as a Key to Understanding the Environmental Fate of Organic Xenobiotics, by Ryan E. Casey and Faith A. Pittman. The paper describes an interesting approach to introducing students in an environmental science course, with no required chemistry background, to important questions of the ways in which molecular geometry and polarity affect the behavior of organic molecules in the environment.
