Discusses how color-coded overhead transparencies of computer-generated dot-density diagrams can be used to illustrate hybrid orbitals and the principle of the indistinguishability of electrons. (MLH)

Briefly discusses Alfred Werner's discovery of the coordination theory of inorganic chemistry. (MLH)

Discusses planning for non-structural laboratory items, such as desks, instruments, and high purity water systems. (MLH)

Discusses the difficulty of explaining the concept of entropy, and provides exercises, experiments, and discussions concerning entropy. (MLH)

Suggests several mechanisms for catalysis by metal ion complexes. Discusses the principal factors of importance in these catalysis reactions and suggests reactions suitable for laboratory study. (MLH)

Presents an inorganic oxidation-reduction kinetics experiment, and describes a low cost (less than $50) modification of the Bausch and Lomb Spectronic 20 Colorimeter which will provide a linear output in absorbance. (MLH)

Illustrates the mathematical relationships between the enthalpy, free energy, and entropy of a chemical reaction using the first and second laws of thermodynamics. (MLH)

Describes a computerized test administration procedure that solves the problem of providing enough different tests for a self-paced chemistry course. The computer randomly generates a new test for each student from a bank of test items, then grades the test, and gives immediate feedback to the student. (MLH)

Describes computer programs and projects designed to assist the chemical researcher in solving problems on-line. Discusses programs that interpret molecular structures, analyze multivariant data, and generate structural isomers of compounds. (MLH)

Included are abstracts of 48 books on natural and physical sciences, predominately chemistry, available from English publishers. Included are order addresses and price, in English currency. (SL)

Reviews the English booklet, "Safety in Science Laboratories." Included in the booklet is a discussion of teacher roles in ensuring safety in chemistry and biology laboratories. (SL)

Describes a lighted demonstration apparatus for representing the distribution of electrons, protons and neutrons in an atom. Also includes experiments with ice, forces, microscopes, spectra, and geological modeling. (CS)

Summarizes five papers presented at the Fourth Biennial Conference on Chemical Education that dealt with the impact of increased subscription costs of chemical information publications and ways of providing information services to students. (MLH)

Describes a computer program that generates a random string of amino acids and guides the student in determining the correct sequence of a given protein by using experimental analytic data for that protein. (MLH)

Reviews the principles of liquid chromatography with electrochemical detection (LCEC), an analytical technique that incorporates the advantages of both liquids chromatography and electrochemistry. Also suggests laboratory experiments using this technique. (MLH)
