We are “star stuff”. Discuss in detail our connections to the stars as established by modern astronomy. Modern astronomy has allowed us to understand how the universe functions and also provides the answers to some of the big questions. Questions like the origin of the universe and origin of life itself. It tells us that stars are the cosmic furnaces where all most all the building blocks of life and planets were synthesized. Lighter‚ basic and abundant elements like hydrogen and helium

contains inorganic compounds. Paint tends to be inorganic in nature. The white‚ red‚ yellow pigments of paint is inorganic by nature. Organic compounds are based on carbon these are found only on living things. Inorganic is the opposite it doesnt come from living things its from synthetic fibers like polyester or nylon are carbon based but are not found in plants or animals. From a forensics science point of view both inorganic and organic compounds are very important when found in items of evidence

hydrocarbon accumulation Phases of alteration of organic matter Types of kerogen Migration of hydrocarbons Five Major Types of Hydrocarbons Kerogen: Kerogen is a fine-grained‚ amorphous organic matter. It is not soluble to normal petroleum solvents‚ like carbon disulfide. Its chemical composition is 75% C‚ 10% H‚ 15% other (sulfur‚ oxygen‚ nitrogen‚ etc.). It is very important in the formation of hydrocarbons because it is what generates oil and gas. Source rocks must contain significant amounts of kerogen

fullerene with glycine. These higher atomic charges of exohedrally functioned doped fullerenes with glycine surface can be increased storage capacity. The binding energy of glycine to doped fullerene generated a more stable structure through metal ion-carbon atoms. NMR Analysis shows the property of the aromaticity of doped fullerene with glycine. Moreover‚ the simulated vibrational spectra of main characteristic peaks are assigned in doped and undoped fullerene with glycine. The theoretical calculatin

elimination process on the dibrominated product. This process is considered “greener” compared to the original bromination procedures. In order to create the alkyl halides‚ which are able to undergo chemical transformations more readily than the carbon-carbon double bond‚ onto the trans-stilbene the addition process of halogenation in needed. The typical reagents that are used‚ such as elemental bromine and liquid bromine‚ are dangerous and highly corrosive‚ so this experiment used an alternative method

Institute of Technology [pic] ABSTRACT Elemental analysis of organic compounds determine the elements present in them but they do not give the actual structure or the functional groups present. Since all organic compounds contain hydrogen and carbon‚ most tests consist of only the determination of oxygen‚ sulfur‚ nitrogen and halogens – elements that are most of the time the only ones involved in organic compounds. The experiment focused on the Sodium Fusion test‚ which tested for all elements

plastics are used in packaging. This puts special pressure on the EUR 500billion packaging industry to reduce dependence on oil. Alleviating such heavy reliance on petroleum‚ the use of renewable natural resources in industrial applications will reduce carbon footprint attributable to consumption. However‚ undertaking the movement to create more environmentally friendly plastic should not compromise the quality or economic competitiveness of the products. As a solution to this problem‚ VTT Technical Research

EXPERIMENT 8 BOILING POINT n-Butyl Alcohol n-Butyl Alcohol‚ a four carbon straight chain alcohol‚ is a volatile‚ clear liquid with a strong alcoholic odor; miscible with water. It is flammable strongly with a luminous flame. Formula: C4H9OH Boiling point: 118 ºC Melting point: -89 ºC Tert-Butyl Alcohol Tert-Butyl Alcohol or “2-methyl-2-propanol” is the simplest tertiary alcohol. It is one of the four isomers of butanol. Tert-Butanol is a clear liquid (or a colorless solid‚ depending on
