Describes the construction and operation of a temperature programmer; it can be built for less than $100 and can be used with any gas chromatograph that uses a variable resistor to control oven temperature. (MLH)

Presents six papers that were presented at a one-day symposium dealing with the influence of textbooks on chemical education. Specific topics include textbooks in inorganic, organic, analytical, and physical chemistry, and the history of chemistry textbooks in the United States. (MLH)

Discusses topics about the structure of the solid state that are suitable for introductory chemistry; included are unit cells and simple molecular structures. (MLH)

Discusses the coordinated polyhedra approach to teaching the solid state. A solid is viewed as a collection of coordination complexes. Also proposes a method of extending the current chemical symbolism to include structural facts of solid state chemistry. (MLH)

Discusses an equation that describes the variation with temperature of acid dissociation constants. (MLH)

Discusses gel chromatography of metal ions, ligands, and resultant metal complexes; how this method can be used to determine stability constants is considered. (MLH)

Discusses the concepts involved in constructing a meaningful free energy plot for a chemical reaction and how these concepts are sometimes insufficiently represented in textbooks. (MLH)

Discusses the stability of the three-electron bond from a thermodynamic and kinetic standpoint using molecular orbital theory. (MLH)

Discusses the nomenclature of inorganic oxo acids in which the central atom is bonded to one or more organic residues; also considered are their salts and esters. (MLH)

Discusses the preparation of compounds representing six oxidation states of manganese; demonstrations involving these compounds are described. (MLH)

Discusses the philosophy and operation of a chemistry course that emphasizes the impact of chemical science on society and the education of scientifically literate citizens. (MLH)

Discusses a comparison of the relative effects on the stomach of a strong acid, hydrochloric acid, and a weak acid, aspirin. Also discusses molecular geometrics using the Valence Shell Electron Repulsion Theory. (MLH)

Describes a chemistry filmstrip program, available to students as a supplementary study aid; it involves the use of a multi-slide format with four frames per 35mm frame, a hand-held plastic viewer-magnifier, and printed explanations of the visuals. (MLH)

Presents questions and answers concerning chemical aspects of air pollutants and the metabolism of drugs and poisons. (MLH)

Describes a graduate quantum mechanics projects in which students write a computer program that performs ab initio calculations on the electronic structure of a simple molecule. Theoretical potential energy curves are produced. (MLH)
