concentrations of the other major components of Red Bull and Sugar Free Red Bull were not obtained because analysis of those compounds required a higher degree of expertise than can be offered for this lab and will be identified by process of comparison‚ elimination and two dimensional spectral analysis where both protons and carbon 13 are examined to identify and quantify a compound that does not show up on a one dimensional NMR spectrum. This experiment will allow students to gain a better understanding

Discussion An empirical formula is a formula for a chemical compound found by direct laboratory examination. Laboratory procedures allow the chemist to find the simplest whole number ratio of elements within the compound. In order to find the true molecular formula‚ the chemist also needs to know the compound’s molecular mass. The general procedure is to use laboratory techniques to determine the mass of each element in the compound. In this lab‚ we will react a known quantity of magnesium metal

in the Pacific Northwest. Many drug companies and natural products chemists are now turning to the ocean as a source of similar helpful substances. Biotechnology tools are used in identifying‚ isolating‚ characterizing‚ testing‚ and synthesizing compounds discovered in marine animals and plants and then developed into drugs or other products (Fenical‚ 1993; Davidson‚ 1995; Kobayashi and Ishibashi‚ 1993).

Arene Molybdenum lab Introduction: Organometallic chemistry is the study of chemical compounds that contain carbon atoms bound to a metal atom. Organometallic compounds can contain main group elements‚ or more metallic elements such as zinc or carbon. These compounds tend to have carbon atoms bound to the metal center by σ-bonds. Alternatively‚ transition metals can be involved in the compound‚ which leads to a variety of interesting and diverse chemical characteristics. For example‚ a promising

Antioxidants November 23‚ 2012 Organic chemistry is the study of structure‚ properties and the reactions dealing with carbon compounds (organic chemistry‚ n.d.). This type of chemistry may deal with small items‚ but knowing how organic chemistry works as a whole has an impact on our daily lives and also the occupations some of us consider. Knowing the bases of organic chemistry can be important and sometimes even required to learn for the bases of many health care professions

Para-nitrobenzeneazoresorcinol dye and methyl orange belong to a class of dyes known as “azo colors” which contain the azo group linked to two aromatic nuclei. The nature of the aromatic substituent’s on both sides of the azo group (-N=N-) controls the colors of the azo compound as well as the water- solubility of dyes and how well they bind to a particular fabric. In addition to the azo group‚ the dyes
