Discusses a revised and extended version of the Mulliken electronegativities. Describes applications and limitations implied by this version. (CW)

Contains a discussion of applications of principles of electronegativity. Concentrates on partial charges on atoms in a variety of compounds. (CW)

Discusses the incorporation of environmental chemistry topics into the traditional high school chemistry curriculum. Describes and provides lesson plans for the sulfur cycle and acid rain, and radioactivity and nuclear energy. Considers possible laboratory experiments. (CW)

Describes a one-semester course in environmental chemistry for students who have had a full year of introductory level chemistry. Illustrates how material from this upper-level course was integrated into a general chemistry course. Examples of content are provided. (CW)

Discusses general statistical methods which could be employed to develop homework problems and laboratory exercises. Methods emphasize experimental design and the effects of uncertainties on inferences drawn from experimental data. (CW)

Provides an introduction to and summaries of the manufacturing methods and uses of chemicals 51-75 on the list of chemicals arranged in order of decreasing production in the United States. Gives production in pounds, annual growth, average price per pound, and organization according to the seven basic organic chemicals. (CW)

Defines the rate-controlling step in contrast to the terms rate determining and rate limiting. Discusses the usefulness of this concept in describing kinetic isotope effects, consecutive reactions, chain reactions, and enzyme-catalyzed reactions. (CW)

Discusses how problem-solving networks can be incorporated into courses. Reports on the development of a new style of pictorial network that can assist students in the handling of experimental data. (CW)

Describes a demonstration procedure using controlled reduction potentials to predict observed color changes which are then experimentally verified. Demonstrates the usefulness of this procedure in helping students understand LeChatelier's principle and the solubilit rule "like dissolves like." (CW)

Describes two demonstrations for use in college chemistry classes. Includes "Spectroscopy in Large Lecture Halls" and "The Endothermic Dissolution of Ammonium Nitrate." Gives materials lists and procedures as well as a discussion of the results. (CW)

Describes experiments designed to measure the oxygen content in the atmosphere and related areas in the high school laboratories. Considers the application of these activities to other programs. Includes a description of the binuclear complex and recommended procedures. (CW)

Discusses some of the drawbacks of using a demonstration of the electrolysis of water to illustrate the interconversion between electrical and chemical energy. Illustrates a simple apparatus allowing demonstration of this concept while overcoming these drawbacks. (CW)

Presents a study designed to evaluate the influence of temperature on the equilibrium and the structural changes of the complexes interpreted in terms of ligand field theory. (CW)

Reviews three computer software packages for Apple II computers. Includes "Simulation of Hemoglobin Function,""Solution Equilibrium Problems," and "Thin-Layer Chromatography." Contains ratings of ease of use, subject matter content, pedagogic value, and student reaction according to two separate reviewers for each program. (CW)

Lists alphabetically the definitions of key organic-based terms used in characterizing the structure of polymers. Includes several common polymers, some of their uses and their respective structures. (CW)
