Describes a computer simulation experiment in which physical chemistry students can determine all of the kinetic parameters of a reaction, such as order of the reaction with respect to each reagent, forward and reverse rate constants for the overall reaction, and forward and reverse activation energies. (MLH)

Describes an experiment in which general and physical chemistry students can determine the heat of vaporization of a volatile substance from experimental laboratory data using timesharing techniques. (MLH)

Describes a procedure for periodically sampling varying analog signals and storing its digitized signal in the computer. (MLH)

Describes an experiment which measures the surface tension of a liquid and illustrates interfacial spreading and the Marangoni effect. (MLH)

Isomeric ketones containing six or seven carbons are separated, illustrating the capability of chemical instrumentation for separating a group of closely related compounds. (MLH)

Describes an organic chemistry experiment in which seven possible mechanisms for the isomerization reaction are tested with simple sense observations and melting point determinations. (MLH)

The use of atomic absorption techniques to determine heavy metals in trace amounts is demonstrated by analyzing a solution of human hair digested in nitric acid. (MLH)

Describes qualitative and quantitative experiments using ion exchange columns; after introductory exercises the students determine the total ion concentration in sea water and blood plasma. (MLH)

Describes an experiment in which the iron content of a commercial vitamin tablet is determined by comparing its visible spectrum to the visible spectrum of a standardized iron solution. (MLH)

States that it would be inappropriate to give in to student demands that they be taught according to their own standards, needs, and perceptions. The young must be introduced to intellectual discipline before they can appreciate its power. Outlines a curriculum design that would accomplish this goal. (GS)

Describes a student project which requires limited knowledge of Fortran and only minimal computing resources. The results illustrate such important principles of quantum mechanics as the variation theorem and the virial theorem. Presents sample calculations and the subprogram for energy calculations. (GS)

Presents a series of calculations, appropriate for the freshman level, to determine the flow of electrons to oxygen along the electron transport chain. States that living organisms resemble fuel cells and develops calculations for determining power output. (GS)
