CFCs (chlorofluorocarbons) are not natural gases. They are completely made by man. Because they contain chlorine and bromine they began to destroy the ozone layer before they were banned. HCFCs were then used as a temporary measure as they were not so dangerous, but they are now being phased out in favour of HFCs, which do no damage to ozone.
Chlorofluorocarbons are usually colorless gases or liquids.
Chlorofluorocarbons are thought to deteriorate the ozone.
It depends on which chlorofluorocarbons you're talking about. CCl3F (Freon-11) is about 77.5 mass percent chlorine, so 38.0 grams of it would contain about 29.5 grams of chlorine. Other chlorofluorocarbons have different formulae and therefore contain different amounts of chlorine.
Chlorofluorocarbons (CFCs) build up in the atmosphere when they are released from products like refrigerants and aerosols. Once in the atmosphere, CFCs break down and release chlorine atoms, which then catalyze the destruction of ozone molecules in the ozone layer.
Chlorofluorocarbons (CFCs) are synthetic compounds made up of carbon, chlorine, and fluorine. They were commonly used in aerosol sprays, refrigerants, and solvents. However, they have been largely phased out due to their harmful effects on the ozone layer.
Chlorofluorocarbons as always are the reply. These are the gases with most ozone depletion potential. The potential is too high to be imagined.CFCs (chlorofluorocarbons).
Chlorofluorocarbons destroy ozone. It is vital for earth.
CFC's are man made chemicals. They react with ozone and deplete it.
CFCs (chlorofluorocarbons) are man-made gases that are also greenhouse gases.
Chlorofluorocarbons (CFCs), once described as "miracle chemicals," because of the breakdown of the ozone layer that protects the earth from the sun's ultraviolet (UV) radiation which they caused.
Chlorofluorocarbons are usually colorless gases or liquids.
Chemicals known as chlorofluorocarbons damage the ozone layer.
Chlorofluorocarbons are compounds made of carbon, chlorine, fluorine, and hydrogen. They are bad for the environment and come from aerosol sprays and refrigerators.
When chlorofluorocarbons (CFCs) are exposed to ultraviolet radiation in the stratosphere, they release chlorine atoms. These chlorine atoms react with ozone (O3) molecules, breaking them apart and leading to the depletion of the ozone layer.
The anagram is chlorofluorocarbons (CFC's, e.g. some freons).
yes
Cfc's are unique in that they are man made. Leaks in old air handling systems are the primary cause.
