In order to use the Earth’s resources effectively and efficiently‚ it is necessary to understand the properties of the elements and compounds found in mixtures that make up earth materials. Applying appropriate models‚ theories and laws of chemistry to the range of earth materials allows a useful classification of the materials and a better understanding of the properties of substances

thin-layer chromatography or TLC. Introduction and Background: TLC is a quick and convenient chromatographic method for analyzing a mixture by separating its constituent compounds. Along with determining the number of components in a mixture‚ TLC can also be of aid in identifying unknown compounds. Separation of compounds is achieved as a partitioning occurs between a mobile phase and a stationary phase. In TLC‚ the stationary phase is composed of a thin layer of the highly polar silica gel that

The objective of the experiment was to differentiate mammalian C2C12 cells into muscle cells and analyze for presence of myosin light chain. Utilizing Western Blotting techniques and using specific antibodies helped to detect myosin light chain. The hypothesis was that proliferating myoblasts could be induced to initiate the differentiation process by depriving the cells of the necessary growth factors and that the differentiation is characterized by the expression of muscle-specific proteins. The

Emission Spectra & Flame Tests Intro The emission spectrum is used in modern chemistry to help further studies of wavelengths and the spectrum. When a metal in a compound reacts in a flame and produces a color‚ it helps to show the strongest color in the emission spectrum. The purpose of performing these operations on the flame was to see how different metals would react. Using a spectroscope‚ it is possible to observe the line emission spectrum produced by sunlight‚ artificial light‚ and

Nevertheless‚ the similarity of odor to different compounds can be a source of error. For instance‚ the way humans detect odors is due to the presence of seven different receptors in the olfactory area. When smelling different compounds‚ some odor chemicals bind with olfactory receptors easily‚ and other odors need more time to bind with receptors. Therefore‚ after smelling different compounds one after the other‚ the receptors can be altered and associate the previous

1)Calculate the amount of your compound interest investment after 10 years. Remember that you are starting with $7‚500. $10‚642.83 work: A=7500(1+3.5%/365)^365x10 = 7500(1+0.00009589)^365x10 = 7500(1.00009589)^3650 = 7500(1.419041609) = 10‚642.83 2)Calculate the amount of your simple interest investment after 10 years. Remember to use the same rate and compounding as in #1. $2‚625 work: 7500x.035x10 = 7500x.35=2625 3)Create a graph that shows the growth of your compound interest and simple interest

single reference compound. The composition of the unknown mixture and two single unknowns were determined by spotting the reference compounds and the unknown compounds on two TLC plates. Placed them in a developing chamber that contained 0.5% acetic acid in ethyl acetate solvent and observed the TLC plates under UV light after the TLC plates were taken out of the developing chamber. The known reference compounds portrayed spots and calculated Rf values that the unknown compounds matched to. This

CODE: CHM 121 ‚ UNIT: 2.0 . INTRODUCTORY AND IMPORTANCE OF ORGANIC CHEMISTRY Organic chemistry is the study of the compounds of carbon. Carbon compounds are far more numerous than those of other elements because carbon are able to bond together to form a wide range of chains and rings. The subject is named organic chemistry because living organisms are composed of carbon compounds. Organic chemistry could be regarded as the chemistry of life. Organic Chemistry is of great medical‚ economic
