Radical Chain Reaction - Free radicals are molecules that, through photolysis or chemical reaction, have an unpaired electron in their outer valance shell. These radicals are very reactive and thus have a short life.
radical an atom or group of atoms with at least one unpaired electrons. reagent ...
radical : A group of atoms that is capable of remaining unchanged during a series of chemical reactions. Such combinations (radicals) exist in the molecules of many organic compounds; sulfate (SO42-) is an inorganic radical.
Free radicals can be formed in biological materials (e.g. DNA ) when they undergo Ionisation (by interaction with Ionising Radiation ).
Polar Stratospheric Clouds (PSC's) The medium in which reservior chlorine comounds are converted into ozone-destroying chlorine radicals. They are clouds of ice/water particles, typically found at frost point in the stratosphere. More Information.
Radical nitrogen-based molecules that can act to facilitate nitrosylation reactions; reactive nitrogen species include dioxidonitrogen(-) (nitrogen dioxide, nitryl radical) NO2-, ...
Cation: A positively charged atom or radical. Cation Exchange Capacity (CEC): A measure of the availability of cations that can be displaced from a solid surface and exchanged for other cations.
deep (or dark) green: someone who believes we need a radical transformation to a more sustainable society. Also, the belief environmental sustainability should have primacy over economic and social factors.
ion An electrically charged atom, radical (such as SO42-) or molecule formed by the loss or gain of one or more electrons. ionic concentration The concentration of any ion in solution, usually expressed in moles per liter.
Ozone photolysis by UV light leads to production of the hydroxyl radical and this plays a part in the removal of hydrocarbons from the air, ...
Carboxyl Carboxylic the uni-valent acid radical (-COOH), present in most organic acids, this making them bio-degradable. ...
A Buffalo nickel (though sometimes other coins are used) physically modified into a radically different design. Holder A contrivance for storing a coin.
Wet air oxidation a process that treats waste water containing high strength or hazardous organic chemicals by a combination of high temperature and pressure that creates highly reactive hydroxyl radicals ...
As a result, it doesn't really matter from the standpoint of global warming mitigation where a reduction takes place. Carbon offsets are intended to take advantage of the radically different costs and practicalities of achieving GHG emission ...
" But in fact, it presents a view that is radically contrary to the scientific consensus on this issue.
humus high-molecular-weight organic molecules, polymeric, derived mostly from plant decay; humic acids with the COOH radical; humolimnic acids in lake waters and sediments ...
Glycoside A derivative of glucose (or another sugar) in which one hydrogen atom is replaced by an organic radical. (= Glucosinolate.) Gonad Organs of animals which produce gametes.
