Chemistry in action Core curriculum video libraries (Cambridge educational (Firm)) Core curriculum video library Essential chemistry (New York, N.Y.) Physics in action Standard deviants core curriculumSummary: 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...

Summary: An elephant and a racing car don't have much in common-except for the remarkable fact that they're made of similar fundamental building blocks. This program takes a simulated subatomic look at a glass of water to better understand the nature of matter, a minuscule world of molecules, atoms, and elementary particles. The behavior of matter under the effects of gravity, electromagnetism, and the...

Summary: Two very important products derived from air are ammonia and nitric acid. Ammonia is produced when hydrogen gas is extracted from natural gas and steam, mixed with nitrogen from the air, and heated. The resulting ammonia gas is condensed into liquid form, to be made into other chemicals. Ammonia is also used to make nitric acid, basic in the production of fertilizers, detergents, and many other...

Summary: Air, an important industrial raw material, is first filtered to remove any solid matter. Then its constituent gases-nitrogen, oxygen, and other trace gases-can be separated by compressing the air, cooling it, and then allowing it to expand, which cools it further. Since each gas liquefies at a different temperature, the gases can easily be separated. As the air expands, it is used to drive...

Summary: A good way to introduce quantum theory is to profile the individuals who pioneered it. This program focuses on Niels Bohr's contributions to our understanding of the atom and the behavior of subatomic particles according to quantum mechanics. Outlining theoretical precursors of quantum physics-including the ideas of John Dalton and J. J. Thomson-and a brief biography of Bohr, the video shows...

Summary: In this program, bonding is explained in terms of dipole-dipole bonding for polar molecules, and dispersion forces for both polar and nonpolar molecules. Changes of state for water are examined, and the decreased density of ice when compared with liquid water is explained in terms of intermolecular bonding. Polarity is explained within the context of electronegativity. Formation of...

Summary: Can a barbershop quartet introduce the subject of stoichiometry? They do in this program, which in section one presents the Law of Conservation of Mass and how to balance equations. Section two explains the difference between the mass number and atomic mass, what an isotope is, and how to work with atomic mass units to find the average atomic mass.

Summary: After a short discussion of why chemical bonding occurs, this program explains how electrons are shared in covalent compounds. Viewers learn about the VSEPR theory, the two types of weak forces of attraction between molecules, dipole interactions and dispersion forces, and covalent network solids such as diamond, graphite, and fullerenes. With the assistance of animated graphics, the video...

Summary: This program considers the bonds formed when atoms share electrons (covalent bonding) The idea of filling electron shells to reach a more stable state is used to explain the formation of simple molecules such as water and methane. Shapes of molecules are explained by considering the repulsion between molecular orbitals. Further shapes are illustrated using CH4, NH3, and NH4. Double bonds (O2)...

Summary: Why is the acronym VSEPR pronounced "vesper"? The answer to that question is the only thing not revealed in part one of this program, which takes a look at the VSEPR theory, non-bonding electron pairs, polarity, and dipoles. In part two, a "cow-chicken" and other experts elucidate the theories of hybrid orbital and molecular orbital overlap and illustrate how to determine bond order.
