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; 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 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...
Chemistry-Study and teaching; Handouts; Quantum theory; Eigenfunctions; Perturbation (Quantum dynamics)
Handout on perturbation theory in quantum mechanics written by the instructor as a supplement to the textbook. It looks at an approach for the case where a problem differs slightly from one that can be solved exactly.
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.
Handout from the laboratory manual explaining curve fitting and the method of least squares. Included is a least squares exercise using Microsoft Excel.
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; Molecules-Models; Lewis dot structures; Molecular structure
Experiment designed to acquaint a student with selected but instructive techniques of molecular modeling. It involves using computational methods to answer chemical questions.
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; 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...
Chemistry-Study and teaching; Atomic structure; Molecular structure; Examinations; Atomic orbitals; Questions and answers; Lewis dot structures; Chemical bonds
Questions and answers for the third midterm examination of Fall 1999, involving six multi-step problems covering atomic and molecular structure.
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.
