Z ideal gas Ideal gas is a gas in which there is complete absence of cohesive forces between the component molecules; the behavior of such a gas can be predicted accurately by the ideal gas equation through all ranges of temperature and pressure. The concept is theoretical, since no actual gas meets the ideal requirement. ideal solution Ideal solution is a solution in which solvent-solvent and solvent-solute interactions are identical, so that properties such as volume and enthalpy are exactly additive. Ideal solutions follow Raoult's law, which states that the vapor pressure p i of component i is p i x i p i , where x i is the mole fraction of component i and p i the vapor pressure of the pure substance i.

Extractions: We have seen that the energies of bound electrons are quantized , and have labelled the energy levels with an integer n. We mentioned that the orbits are not necessarily circular, nor are they planar. Instead, they are three dimensional, so that instead of circular, we have spherical, and instead of elliptical, we have ellipsoidal. In fact, the energy of an atomic electron depends not only on n, but on angular momentum, orientation, and spin as well. These effects are not predicted by the Bohr model, but derive from the more advanced (and complicated!) Schrodinger and Dirac Equations. We therefore "label" an atomic electron by four "quantum numbers": n = 1, 2, 3, ...., denoting energy; l = 0, 1, ..., n-1, denoting angular momentum m = - l l , denoting orientation (the "magnetic quantum number"), s = -1/2, 1/2, denoting spin (m s is also used in place of s). The set of four numbers (n, l , m,s) identifies the "quantum state" of the electron. Chemists use letters in place of numbers for l (s, p, d, f, etc.), and so an n=3

Extractions: During the Ph.D. study, biosynthesis and chemotaxonomy of secoiridoid glucosides (a class of monoterpenoids) were investigated. This included semi-syntheses of deuterium-labelled precursors, biosynthetic feeding experiments and determination of incorporation in the isolated metabolites by 2H NMR spectroscopy. The biosynthetic pathways were examined in species of the Olive family. In addition, the structures of several novel iridoid glucosides and phenylpropanoids were determined.

Extractions: Prof. Stephen A. Nelson Geology 211 Tulane University Mineralogy Crystal Chemistry As we have been discussing for the last several weeks, crystals, and thus minerals, are made up of a 3-dimensional array of atoms arranged in an orderly fashion. Now we explore what these atoms are and how they interact with one another to determine the physical and structural properties of crystals. So, first we explore the properties of the atom. Atoms Atoms make up the chemical elements. Each chemical element has nearly identical atoms. An atom is composed of three different particles: Protons positively charged, reside in the center of the atom called the nucleus.
