Introduction. The purpose of this short discussion is to provide a correct yet understandable introduction to thermodynamics. It is intended to replace and not complement the material in your text. The author is schooled in the Oberlin school of...
Handout on the grading policies for laboratory experiments in accelerated General Chemistry. It lists a number of factors which are taken into consideration when grading the laboratory reports.
Handout explaining systematic and random errors, precision versus accuracy, significant figures, absolute and relative error, propagation of errors, measurement distribution, etc.
Handout from the laboratory manual explaining curve fitting and the method of least squares. Included is a least squares exercise using Microsoft Excel.

Exercise dealing with rate laws and mechanisms, using a special computer program to simulate an experiment. The exercise focuses on the experimental design and an analysis of the results.
Chemistry-Study and teaching; Homework; Molecular orbitals; Chemical bonds
Introduction: In class we applied molecular orbital theory to a few simple examples with the goal of understanding the nature of the chemical bond. The qualitative approach is complemented by numerical calculations and the interpretation of these...
Chemistry-Study and teaching; Gas chromatography; Mass spectrometry
Experiment involving the isolation, concentration, separation and identification of the volatile components of a foodstuff (via headspace analysis, capillary gas chromatography, and mass spectra measurements).
Chemistry-Study and teaching; Absorption spectra; Solution (Chemistry); Spectroscopy, Atomic absorption
Experiment consisting of preparing a series of standard solutions containing iron and solutions of metallic alloy samples, then measuring the absorption of light by the atoms of the element when the solutions are aspirated into a flame.
Chemistry-Study and teaching; Handouts; Valence (Theoretical chemistry); Chemical bonds; Electrons; Molecular orbitals
In class, we have used the Valence Bond (VB) approach to understand chemical
bonding. At the qualitative level, VB is relatively easy to use and does not require a deep
knowledge of quantum mechanics and group theory. The electron-dot formalism of...
Handout providing a list of sources of data in the library. Specifically, it provides a list of the most useful
compilations of numerical data need for planning experiments and for the analysis of experimental results.
Chemistry-Study and teaching; Handouts; Solution (Chemistry)
Experiment in which the objective is to separate, by gas chromatographic techniques, a mixture of the four isomeric butyl alcohols and to determine the percentage of each an unknown mixture.
