Calorimeter, Coffee Cup (ChemPages Lab) John W. Moore, Jerrold J. Jacobsen, Joe L. March
Calorimeter, Coffee Cup: this is a resource in the collection "ChemPages Laboratory Resources". A coffee cup calorimeter is a useful, simple device that can be used to measure the temperature change that accompanies a reaction. A Styrofoam cup is used because it is a good insulator. The cup will absorb (or supply) negligible amounts of heat during most General Chemistry experiments. Thus, any change in temperature is assumed to be due only to the reaction, and the heat transferred in the reaction may be calculated. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.

Molecular Model of Zincon William F. Coleman
The Featured Molecules this month are the tautomeric forms of the colorimetric reagent zincon, used in the paper by Maria Mar Areco, Maria dos Santos Afonso, and Erika Valdman on the bioabsorption of zinc, and by extension other metal ions, by seaweed. The structures presented have been calculated at the DFT/6-31G(d) level using the B3LYP functional. These structures represent energy minima, but not necessarily global minima. The structures could be used as an introduction to the concept of tautomerism, with students being asked to develop a definition of the term based on their observations of the difference(s) in linkage in the two forms. An intramolecular hydrogen bond is found in each structure, and introductory chemistry students could be encouraged to look for these structural features in molecules that are more complex than those typically encountered to introduce hydrogen bonding. More advanced students could use computational techniques to explore the energy differences between the two forms, and compare those differences to the ones observed between more traditional keto/enol examples.

Disorder (GCMP) David M. Whisnant
Disorder: this is a resource in the collection "General Chemistry Multimedia Problems". A spontaneous change is one that has a natural tendency to occur without needing to be driven by an external influence. This problem will explore the influence of entropy, a measure of disorder, on the spontaneity of a few processes. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.

A Lattice Energy Spreadsheet Christopher King
A Lattice Energy Spreadsheet is a tool that easily calculates lattice energies. It also illustrates the relation between crystal structure, coordination number, and ionic radii. A Lattice Energy Spreadsheet contains five related worksheets: Lattice Energy, MX Structure Map, Kapustinsky Lattice Energy, Directions, and Discussion, each described below. In the Lattice Energy worksheet, the lattice energy of many binary compounds can be calculated in about a dozen mouse clicks. An element is selected, and the radius corresponding to the desired charge and coordination number is selected. The same is done for the counter ion, and the anticipated crystal structure of the compound is chosen (rock salt, wurtzite, etc.). The lattice energy is then calculated. This sheet uses enthalpies of formation of monatomic gaseous atoms from the elements, ΔH°form, to calculate lattice energies. The results are more accurate than the values obtained by simply summing enthalpies of fusion and vaporization. The results of the corresponding Born-Haber cycle are also graphed on this sheet.

A Pedagogical Simulation of Maxwell's Demon Paradox D. López, C. Criado
Maxwell's demon was conceived by James Clerk Maxwell in 1871 to illustrate the statistical basis of thermodynamics (1), and the concept has since formed an arena for investigation and clarification of many concepts in thermodynamics (2). Chemistry students often have difficulty developing an intuitive knowledge of some concepts in thermodynamics. A Pedagogical Simulation of Maxwell's Demon aims to help make these concepts more understandable for students. Teaching thermodynamics from the microscopic point of view can help students develop an intuitive understanding of its concepts. This program simulates, at the microscopic level, two gas chambers with an opening between them. The program allows students or their instructors to set up simulations that illustrate the thermodynamics and statistical behavior of the system. The user determines the basis for whether the demon permits or denies passage of particles through the opening using information from the microscopic level, such as specific particle velocity. Students can track and analyze how this affects particle distribution, thermal equilibrium, relaxation time, diffusion, and distribution of particle velocities.

Contrail. A Module from the Physical Chemistry On-Line Project Franklin M. C. Chen
The condensation trail, or contrail, that trails behind a jet plane is an everyday observable phenomenon. These manmade cirrus clouds can persist for hours, or even days and can spread over thousands of square kilometers. This is a concern because clouds are major variables that control Earth's atmospheric temperature and climate. Understanding the impact of contrails on Earth's climate is an active area of research. Further, contrail formation can be examined in terms of the operative thermodynamic phenomena. The process of contrail formation involves combustion, cooling, and ice formation, all common topics in the undergraduate physical chemistry curriculum. The project when it is subdivided into separate manageable subjects is a good, comprehensive exercise for physical chemistry students.

JavaScript Programs To Calculate Thermodynamic Properties Using Cubic Equations of State Patrick J. Barrie
Cubic equations of state are widely used by chemists and chemical engineers to predict the thermodynamic properties of both pure substances and mixtures. In particular, these equations enable predictions concerning the temperature and pressure at which vapor liquid equilibrium occurs. These two educational JavaScript programs perform calculations using cubic equations of state and, equally importantly, explain how the calculations are performed.
