Chemistry-Study and teaching; Handouts; Thermodynamics; First law of thermodynamics; Chemical equilibrium
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...
Chemistry-Study and teaching; Spectroscopy, Nuclear magnetic resonance;
Experiment designed to introduce the fundamental principles and practice of magnetic resonance imaging (MRI), a form of NMR spectroscopy, by obtaining and examining a two-dimensional image of the stem or bud from a plant.
Chemistry-Study and teaching; Handouts; Thermodynamics; Second law of thermodynamics; Chemical equilibrium
Introduction: The First Law of Thermodynamics places important restraints on the path that can be taken by a system but it does not define the path. For example, the First Law does not rule out the possibility of warming oneself by sitting on a...
Chemistry-Study and teaching; Chemical bonds; Transition metals; Molecular orbitals
Introduction. The purpose of this handout is to provide a simple model for the bonding in transition-metal complexes as a framework for understanding and interpreting the most important properties of these complexes. We shall deal mostly with the...
Handout explaining systematic and random errors, precision versus accuracy, significant figures, absolute and relative error, propagation of errors, measurement distribution, etc.
Chemistry-Study and teaching; Voltammetry; Electrochemistry; Solution (Chemistry)
Experiment with the goal of gaining an understanding of anodic stripping voltammetry and an understanding of the factors involved in performing quantitative analytical determinations, through the determinations of amounts of copper.
Chemistry-Study and teaching; Adsorption; Molecular sieves; Gases
Experiment involving studying the adsorption of gaseous nitrogen and dimethyl ether on a molecular sieve; it also provides experience with manipulations on a vacuum line.
Handout from the laboratory manual explaining curve fitting and the method of least squares. Included is a least squares exercise using Microsoft Excel.
Chemistry-Study and teaching; Handouts; Stoichiometry; Chemical equilibrium
Introduction. Part II of the handout will apply the approach introduced in Part I to acid-base chemistry. We shall focus on two cases where the application of stoichiometry leads to great simplifications: strong acids which are essentially 100%...
Chemistry-Study and teaching; Chemical kinetics; Solution (Chemistry)
Experiment involving the study of the kinetics of the reaction between iron(III) and thiocyanate ions by the stopped-flow method, using the HiTech Stopped-Flow System and a digital oscilloscope.
Chemistry-Study and teaching; Spectroscopy, Nuclear magnetic resonance
Experiment previously used in the course and focused on selective irradiation and nuclear magnetic resonance (NMR), specifically involving homonuclear decoupling and the NOE (nuclear Overhauser enhancement) difference experiment.
Chemistry-Study and teaching; Environmental chemistry
An annotated bibliography for Environmental Chemistry, with links to sources of chemical data on the World Wide Web involving general references, toxic properties, degradation of molecules, remote sensing data, environmental problems and methods of...
Chemistry-Study and teaching; Handouts; Homework; Crystals; Solvents; Solution (Chemistry); Electrons
Experiment with the objective of synthesizing an inorganic complex compound in pure form and high yield and of discovering the chemistry involved in the syntheses. Determining the compound's paramagnetic susceptibility is involved.
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; Handouts; Stoichiometry; Chemical equilibrium
Introduction. In class we observed that no reaction goes to completion and have discussed qualitatively the consequences of this insight. It is also possible to deal quantitatively with chemical equilibria. The chemist's approach should start with...
