A previous article stated that only the matrix method was powerful enough to balance a particular chemical equation. Shows how this equation can be balanced without using the matrix method. The approach taken involves writing partial mathematical reactions and redox half-reactions, and combining them to yield the final balanced reaction. (JN)

A workshop was designed to (1) train teachers to become experts on chemical safety and storage; (2) examine and evaluate chemical storage in 12 Carroll County (Maryland) schools; and (3) develop a safety guide for all county science classrooms. Development, implementation, evaluation, and implications of the workshop are addressed. (JN)

Proposes a model for kinetic processes said to be similar in computational effort and yielding similar results to conventional transition state theory (TST), while maintaining parsimony and credulity. Argues that partitioning of states into groups be limited to energy space in contrast to TST. (JM)

Discusses an acid-base neutralization exercise requiring groups of students to determine: (1) combinations of solutions giving neutralization; (2) grouping solutions as acids or bases; and (3) ranking groups in order of concentration. (JM)

The Industrial Associates Program (IAP) at Purdue University is a formal organization to coordinate department-industry interactions. Philosophy, features, and projects of IAP are discussed. Indicates that a new effort will aim at setting up a sort of "Industrial Extension Service" (analogous to agricultural programs) to help industries…

Six high school and college chemistry teachers describe what they do on the first day of class. These edited papers were presented in a symposium titled "My First Day of Class" at the Eighth (1984) Biennial Conference on Chemical Education. (JN)

Describes the properties of colloids, listing those commonly encountered (such as whipped cream, mayonnaise, and fog). Also presents several experiments using colloids and discusses "Silly Putty," a colloid with viscoelastic properties whose counterintuitive properties result from its mixture of polymers. (DH)

Describes an individualized chemistry course based on mastery learning. The course uses the CHEM Study inquiry approach and textbooks with students proceeding at different rates, according to their individual abilities and interests, through a prescribed set of learning activities involving readings, sound pages, films, experiments, problem sets,…

Presents background information and procedures for 12 experiments dealing with such areas as: reactivity of a homologous series of saturated monovalent alcohols; enzymatic degradation of hydrogen peroxide by catalase; effect of an activator and inhibitor on amylase activity; proving the existence of phenol in waste water; detecting common air…

Presents the American Chemical Society (ACS) Committee on Professional Training's 1985 report on bachelor, master, and doctoral graduates of ACS-approved schools. This information is provided in an alphabetical list by institution (with separate columns devoted to chemistry and to chemical engineering). (JN)

Discusses various topics related to the interfacing of computers, focusing particularly on methods of data collection using instruments. Topics include serial digital connections (examining RS 232C and V.24, physical protocol, electrical protocol, and other areas) and parallel digital connections. (JN)

Highlights five major analytical areas (electrophoresis, immunoassay, chromatographic separations, protein and DNA sequencing, and molecular structures determination) and discusses how analytical chemistry could further improve these techniques and thereby have a major impact on biotechnology. (JN)

The use of Beilstein ("Handbuch der Organischen Chemie") in the early stages of a second-year, one semester course in organic chemistry is described. Student literature projects, evaluation, use of ancillary literature, and a sample search are included. (JN)

Discusses topics and issues related to (1) international impact of microcomputers; (2) minimum guidelines for software development; (3) achieving minimum standards; and (4) accomplishments in the areas of introductory chemistry, organic chemistry, analytical chemistry, and physical chemistry. Challenges for the future are noted. (JN)

Presents a module that focuses on the solvent property of water. Indicates the knowledge items, skills, processes, and attitudes that are developed in the unit. Includes background information as well as student directions for an experiment on solubility. (ML)
