The generation of secondary colors in digital devices by means of the additive red, green, and blue color model (RGB) can be a valuable way to introduce students to the basics of spectroscopy. This work has been focused on the spectral separation of secondary colors of light emitted by a computer screen into red, green, and blue bands, and how the…

Introduced to study components of ionized gas, the mass spectrometer has evolved into a highly accurate device now used in many undergraduate and research laboratories. Unfortunately, despite their importance in the formation of future scientists, mass spectrometers remain beyond the financial reach of many high schools and colleges. As a result,…

The [Co(4-pyrimidinolate)[subscript 2](H[subscript 2]O)[subscript n]] species, which can be easily and selectively prepared by simple addition of aqueous solutions of the 4-pyrimidinolate organic ligand to Co(II) acetate (or nitrate) aqueous solutions (n = 4, 6) or by controlled heating of the hydrated phases (n = 0), proved to be versatile…

Described in this article is a problem-solving activity which integrates the application of microcomputers with the learning of physical chemistry. Students use the program with spectroscopic data to calculate the thermodynamic properties and compare them with the values from the thermochemical tables. (Author/KR)

Describes eight uses of the microcomputer in the chemistry classroom. Includes games, simulations, and graphics programs most of which are available from Project SERAPHIM. (MVL)
