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; 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; 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.
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; 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; Wilderness areas; Landscapes
Handout on art and the wilderness, with examples of pieces of artwork, an essay by Rebecca Solnit, and material on the Hudson River School. The handout is from the 2006 version of the ID, Critical Inquiry course.
Handout explaining systematic and random errors, precision versus accuracy, significant figures, absolute and relative error, propagation of errors, measurement distribution, etc.
