Presents a brief discussion of rules for consistent chemical equations writing, intended for college chemistry students and instructors. (HM)

The authors describe a career-enhancement program, at Texas Tech University, for students in chemistry or biology who want to enter the field of chemical engineering. (SA)

The laboratory experiment described here is intended to be of use to the forensic science major enrolled in a course in organic chemistry. The experiment is the use of thin-layer chromotography for qualitative analysis, specifically for the identification of drugs. (Author/SA)

Presented here is a laboratory experiment for a course in physical chemistry. Students are requested to directly measure the degree of orientational order in a liquid crystal at room temperature. A minimum amount of equipment is necessary. (Author/SA)

Describes a typical relaxation kinetic experiment using a sudden increase in the temperature of the system. Time involved is described as minimal and the approach as quicker, more accurate, sensitive, and producing simultaneous determination of several thermodynamic parameters. (Author/SA)

Contains a series of laboratory exercises students can do to introduce them to the basic concepts and techniques of water purification. (Author/MA)

This annual report includes totals of graduates from American Chemical Society approved schools for 1978. The number of bachelors, masters, and doctorates increased by 1.5 percent, 7 percent, and 2 percent, respectively. (BB)

The experiment described, suitable for undergraduate physical chemistry laboratories, illustrates the general principles of relaxation and introduces the nmr concepts of saturation and spin-inversion. (BB)

The cost of dealing with pollution and ensuring an acceptable environment must be regarded as part of the price to be paid for providing ourselves with the products of industrial activity. However, since environmental problems are relative rather than absolute, any judgment of risk needs to be balanced against the assessment of the benefit.…

Explains how to use sticky tape, a soda straw, and a little water to build a device which will demonstrate Charles' law as well as give the temperature. (GA)

The author has rewritten rules for CIPW norm calculation and has written FORTRAN IV programs to assist the student in this procedure. Includes a set of problems utilizing the CIPW norm to illustrate principles of chemical petrology. (MA)

This study utilized the instructional methods of discovery teaching and expository presentation to investigate the concept development of students in a remedial college chemistry class. Results indicate that the two sets of instructional materials did not lead to the same understanding of the concept. (BT)

Presents articles on: the measurement of flouride levels in natural waters; the effect of sunlight on the rate of chlorine decomposition in a swimming pool; and curriculum development in Australian agriculture science. (MLH)

Describes instruments for the quantitative measurement of radioactively tagged organic and biological molecules used as tracers. (MLH)

Discusses the legal implications of situations in which chemical educators may be liable for negligence. (MLH)
