Solow, Mike – Journal of Chemical Education, 2004
Quantification of a contaminant in water provides the first-year general chemistry students with a tangible application of mass spectrometry. The relevance of chemistry to assessing and solving environmental problems is highlighted for students when they perform mass spectroscopy experiments.

Rastogi, R. P.; Shabd, Ram – Journal of Chemical Education, 1983
Presented is a concise and critical account of developments in nonequilibrium thermodynamics. The criterion for stability of nonequilibrium steady states is critically examined for consecutive and monomolecular triangular reactions, autocatalytic reactions, auto-inhibited reactions, and the Lotka-Volterra model.

Bayless, Philip L. – Journal of Chemical Education, 1983
Provides and discusses an equation which, when combined with the well-known Ricci equation for oxyacids, results in a generally useful equation for dealing with acid dissociation experiments and analyses. (JN)

Goldsmith, Robert H. – Journal of Chemical Education, 1983
Isobutylene is an important bulk chemical for the petroleum industry. Dimerization and hydrogenation reactions produce the standard fuel octane rating comparison. This classic chemistry is often misrepresented in modern texts, however, and this paper attempts to correlate the physical organic principles that apply. (Author)

Haque, M. Serajul – Journal of Chemical Education, 1984
There are two conflicting views about the mechanism of 1,3-dipolar cycloadditions to multibonds. To reconcile these viewpoints a concerted, spin-paired, diradical mechanism, based on valence bond theory, is proposed. Each of these three mechanisms is discussed. (JN)

Lineback, David R. – Journal of Chemical Education, 1984
Discusses various aspects related to nutrition and athletics. Examines nutritional requirements, energy use, carbohydrate loading, and myths and fallacies regarding food and athletic performance. Indicates that scientific evidence does not validate the use of any special diet by an athlete. (JN)

Journal of Chemical Education, 1983
Over 500 chemical educators met at Oklahoma State University during August 1982 to assess the condition of chemical education in the United States. Lists of conference organizers, technical program organizers and/or moderators, plenary speakers, special projects coordinators, ancillary program organizers, contributors, exhibitors, conference…

Sharma, B. D. – Journal of Chemical Education, 1982
Compares Schoenflies and Hermann-Mauguin notations of symmetry. Although the former (used by spectroscopists) and latter (used by crystallographers) both describe the same symmetry, there are distinct differences in the manner of description which may lead to confusion in correlating the two notations. (Author/JN)

Harcourt, Richard D. – Journal of Chemical Education, 1985
Recommends the Linnett structure IV (as in VIII for molecular oxygen) for future use when a valence-bond structure for a Pauling 3-electron bond is required. Examples are provided to illustrate why this recommendation is made. (JN)

Chung, Chung-Sun – Journal of Chemical Education, 1985
Four cases which illustrate statistical factors in complexation reactions (where two of the reactants are monodentate ligands) are presented. Included are tables showing statistical factors for the reactions of: (1) square-planar complexes; (2) tetrahedral complexes; and (3) octahedral complexes. (JN)

Muller-Herold, U. – Journal of Chemical Education, 1985
Explores the question "Why are so many stationary states allowed by traditional quantum mechanics not realized in nature?" through discussion of classical observables and superselection rules. Three examples are given that can be used in introductory courses (including the fermion/boson property and the mass of a "nonrelativistic" particle). (JN)

Seaborg, Glenn T. – Journal of Chemical Education, 1985
As background material for a paper on the transuranium elements (SE 537 837), this article reviews: (1) several descriptive terms; (2) nuclear reactions; (3) radioactive decay modes; (4) chemical background; and (5) experimental methods used in this field of research and more broadly in nuclear chemistry.

Nurrenbern, Susan C.; Robinson, William R. – Journal of Chemical Education, 1994
Provides an overview of the area of quantitative research in chemical education, which involves the same components that comprise chemical research: (1) a question or hypothesis; (2) research design; (3) data collection and analysis; and (4) interpretation of results. Includes questions of interest to chemical educators; areas of quantitative…

Levy, George C. – Journal of Chemical Education, 1995
Describes a course in which societal themes of risk/reward analysis and public policy are supplemented with concepts of scientific journalism, public opinion, and law. Topic areas include environmental chemicals and their impact, basic introduction to organic chemistry, and consumer chemicals. Contains 20 references. (DDR)
