Business / Agriculture / Methane: A gas created by anaerobic decomposition of organic compounds. Natural gas is composed mostly of methane. Methane is a so-called greenhouse gas (see greenhouse effect). Agricultural wastes, especially animal wastes, are a major source of methane releases to the atmosphere.


Science / Chemistry / Dichloromethane: (CH2Cl2) Dichloromethane (CH2Cl2) is an organic solvent often use to extract organic substances from samples. It is toxic but much less so than chloroform or carbon tetrachloride, which were previousl MORE


Science / Chemistry / Combustion: A chemical reaction between a fuel and an oxidizing agent that produces heat (and usually, light). For example, the combustion of methane is represented as CH4(g) + 2 O2(g) = CO2(g) + 2 H2O(ell). MORE


Science / Chemistry / Methyl: A group -CH3, derived from methane. For example, CH3Cl is 'methyl chloride' (systematic name: chloromethane); CH3OH is 'methyl alcohol' (systematic name: methanol). MORE

Carbon (C)

Science / Periodic Table of Elements / Carbon (C): Atomic number: 6, Atomic mass: 12.011 g.mol -1, Electronegativity: 2.5, Density: 2.2 at 20°C, Melting point: 3652 °C, Boiling point: 4827 °C, Vanderwaals radius: 0.091 nm, Ionic radius: 0.26 MORE

Natural Gas

Science / Chemistry / Natural Gas: A mixture of methane and other gases, found trapped over petroleum deposits under the earth. MORE

Acetic Acid

Science / Chemistry / Acetic Acid: (CH3COOH, HC2H3O2) ethanoic acid; vinegar acid; methanecarboxylic acid. A simple organic acid that gives vinegar its characteristic odor and flavor. Glacial acetic acid is pure acetic acid. MORE
