Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.
956124
CFCs are made up of chlorine, fluorine and carbon atoms. ... This causes a chain reaction and causes chlorine atoms to steal ozone atoms for a very long time. Before this process is over, the chlorine atom has likely depleted and destroyed thousands of oxygen atoms.

Chlorofluorocarbons (CFCs) are a group of odorless manufactured chemicals. Because they damage the earth's ozone layer, CFCs have been banned since 1996. Before CFCs products were banned, they were used in aerosols, refrigerators, air conditioners, foam food packaging, and fire extinguishers.

CFCs In The Ozone They are a known compound that impacts ozone depletion. CFCs are made up of chlorine, fluorine and carbon atoms. ... It often meets with ozone molecules, or oxygen atoms, and steals oxygen atoms from others. This causes a chain reaction and causes chlorine atoms to steal ozone atoms for a very long time.

Chloro-Fluorocarbon, or CFCs, are sparingly used in refrigerators today. It is commercially known as freon, and can still be found on older refrigerators. The chemical begins its cycle as a pressurized liquid that expands into a gas as it moves through coils within the refrigerator's walls.

ODS include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, and methyl chloroform. ... Although ozone depleting substances, they are less potent at destroying stratospheric ozone than chlorofluorocarbons (CFCs).

Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs). The absorbed energy warms the atmosphere and the surface of the Earth.
599696
CFCs and their associated compounds were developed in the early 1900s as a non-toxic, non-flammable solution to other more dangerous products such as ammonia. ... When the CFCs reach the ozone layer, ultraviolet radiation occurring at this altitude breaks down the compound and releases the chlorine.

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.

HFC's have a 0 Ozone Depletion (ODP) and a small Global Warming Potential. HFC's are said to be the long-term replacement for CFC's and HCFC's. HC's are the fourth group of refrigerants that are not commonly used because they are flammable. They are made up of Hydrogen and Carbon atoms and the have a 0 ODP.

Gases which contributes in greenhouse effect are carbon dioxide, methane, nitrous oxide, ozone, water vapour, Chlorofluorocarbons (CFCs) and, Hydrofluorocarbons (HCFCs and HFCs). Hydrogen is not a greenhouse gas. Hence, the correct answer is 'Hydrogen'.

CFC starts out as a liquid. The pump pushes the CFC through a series of coils in the freezer area. There the chemical turns to a vapour. When it does, it soaks up some of the heat that may be in the freez- er compartment.

Yes, they are. Most refrigerants found in air conditioners, refrigerators, and freezers contain fluorocarbons, and many fluorocarbon compounds contain chlorine. ... The atmospherically benign HFC refrigerants will remain in production, but CFC and HCFC refrigerants will be phased out. Production of CFCs ceased in 1995.
