The purposes of water treatment in a marine steam power plant are to prevent damage to boilers, steam-operated equipment, and steam and condensate lives, and to keep all equipment operating at the highest level of efficiency. This laboratory exercise is designed to provide students with experiences in making accurate boiler water tests and to…

Describes the application of a computer program designed to produce a formula determination simultaneously accounting for both elemental composition and probable isotopic species for a measured ion mass. (SLH)

Describes an experiment which can be used to test for the use of accelerants in the origin of a fire. Involves distillation and gas liquid chromatography to identify the accelerants, thus combining two experiments ordinarily included in the beginning organic laboratory. (SLH)

Discusses the teaching of a junior level physical chemistry course with self-paced instruction to engineering and physical science students. Included are a description of topics and a summary of student responses. (CC)

Discusses advances made in chemical analysis instrumentation used in environmental monitoring. This first of two articles is concerned with analytical instrumentation in which detection and dispersion depend ultimately on the properties of gaseous molecules. (JR)

Presents four examples which illustrate close relationships of chemistry to other disciplines. Indicates that chemistry is composed of many strongly interacting parts and a discipline which is donating to and borrowing from other disciplines. (CC)

Summarizes chemical principles underlying the operation of automobiles and the cause of air pollution, including concentrations of carbon monoxide, unburned hydrocarbons, and oxides of nitrogen. Comments and opinions are made concerning present and future pollution control devices. (CC)

Summarizes current status of our knowledge about acid-base interactions, including Lewis considerations, experimental design, data about donor-acceptor systems, common misconceptions, and hard-soft acid-base model. Indicates that there is the possibility of developing unifying concepts for chemical reactions of inorganic compounds. (CC)

Summarizes the characteristics of critical path methods for preparing curricula, including behavioral definitions of curriculum objectives, module lengths, effects of published network of prerequisites on individually paced learning, and forms of network-based planning. Indicates that the network planning has the advantage of clarifying the place…

Discusses offering of a modular course designed to acquaint the student with methods of observing and quantitatively measuring the properties and reactions of chemicals. Included is a brief sketch of course content and requirements. (CC)
