Aluminum is extracted and purified from clays and rocks at a British plant by purifying bauxite ore to aluminum oxide and reducing this oxide to molten metal. The influence of economic factors is seen in the location of aluminum plants, which consume large amounts of electrical energy. In the United States, plants are located close to the power source rather than to ore deposits; in England, where electricity is uniformly priced throughout the country,...

Filled with real-life demonstrations that support instructive written examples, this program reinforces the basic principles of solving equations for chemical reactions. A brief historical overview describes Marie and Antoine Lavoisier's establishment of the law of conservation of mass, as well as the theoretical contributions of John Dalton. The importance of balancing equations is emphasized, along with a thorough exploration of reaction types....

All matter in the observable universe-from a single blade of grass to a planet in a faraway galaxy-is made up of atoms, molecules, and compounds. This program introduces these minuscule building blocks in five sections: The Nucleus (protons and neutrons, energy shells, binding energy, fission and fusion); The Electrons (quantum numbers, spdf orbitals); The Elements (periodic table, valence electrons, ions and ionization energy, electronegativity,...

Using clever animation and real-world examples, this video gives viewers a solid grounding in the principles of mixtures, how they can form, and how they can be separated. Starting with everyday tools and materials-including a campfire, sugar, water, and magnets-the program illustrates simple and complex experiments that demonstrate a wide range of mixture separation techniques. Viewers will discover the difference between solvents, solutes, and solutions;...

This Science Screen Report uses experiments and everyday phenomena to explore the properties of matter and how physical forces cause state changes at the boiling, melting, freezing, and dew point. The program also demonstrates how different states of matter can be combined in suspensions and solutions and how such mixtures can be separated into their components. Applied chemistry is spotlighted in the areas of food manufacturing and water desalination....

"Organic Structure Analysis is an ideal text for upper-level undergraduate and first-year graduate courses in organic spectroscopy. It provides students with the background necessary to effectively apply spectroscopic data in establishing features of molecular structure. Unique in its coverage, it is the only text that emphasizes strategies, interpretation, modern techniques, and problem solving. The text's major aim is to show how spectra can be...

In part one of this program, chemistry authorities, including "Helium Man" and two janitors, lay down the law-Boyle's Law, Graham's Law, and Dalton's Law. They also present the Kinetic Molecular Theory and the Ideal Gas Equation and elaborate on partial pressures and the difference between diffusion and effusion. Part two investigates kinetic energy; ion-dipole, dipole-dipole, and London dispersion forces; hydrogen bonds; phase diagrams; and vapor...

This program scrutinizes the concept of phase transitions-from naturally occurring changes in state to those created in laboratories-in five sections: Solids, Liquids, and Gases (properties of molecules in different states; hydrogen bonds, dipole-dipole forces, dispersion forces; effects of temperature, pressure, and volume on atomic and molecular movement; Ideal Gas Law); Evaporation and Condensation (intermolecular forces, boiling/condensing point,...
