CFCs (or chloroflurorocarbons), were used in aerosols or as coolants for refrigerators. They are extremely inert, which made them very useful, however, when exposed to UV light, they formed free radicals that reacted with ozone, thereby creating the phenomenon that resulting in a hole in the ozone layer above Antartica. As a result, CFCs were banned by nations after the signing of the Montreal Protocol.

How can you use the word chlorofluorocarbons in a sentence?
Chlorofluorocarbons are thought to deteriorate the ozone.
What chemical compound once used as a propellant in aerosol sprays?
Prior to 1989, trichlorofluoromethane (CFC-11) and dichlorodifluoromethane (CFC-12) were the most used chemical compound in aerosol-spray propellants. Their use has been discontinued under the Montreal Protocol. answer is: FLUOROCARBON..
What color is chlorofluorocarbons?
rainbow :) but with more green
How many grams of Cl are in 38.0 g of each sample of chlorofluorocarbons?
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.
Do not taste chemicals without teacher's permission?
No chemical is supposed to be tasted . Although teacher will never allow for it.......
Which chemical damages the protective ozone layer?

Which chemical has been banned in most of the world because of its role in destroying the ozone layer?
CFCs, Chlorofluorocarbons.
What chemical helped cause the ozone hole?
The chemical which manly caused the ozone hole is Chlorofluorocarbons. These are compounds made of chlorine and fluorine which deplete ozone in large amounts.
What human made chemical damages the ozone layer?
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.
What chemical caused damage to the ozone layer over Antarctica?
The chemical that cause ozone hole over antarctica is CFC. Chlorofluorocarbons are the ones that contain chlorine which deplete ozone layer.
What does chlorofluorocarbons destroy?
Chlorofluorocarbons destroy ozone. It is vital for earth.
How can you use the word chlorofluorocarbons in a sentence?
Chlorofluorocarbons are thought to deteriorate the ozone.
What has had the greatest effect on ozone depletion?
Chlorofluorocarbons (CFCs)
What chemical harms the ozone layer?
Various chemicals can harm the ozone layer.The ones containing halogens are the most harmful.
What first caused the ozone layer depletion?
In the past the chemical CFC (chlorofluorocarbons) was used in refrigerators however a few decades ago it was phased out
Which chemical is mainly responsible for depletion of ozone layer in the atmosphere?
Manmade chemicals like chlorofluorocarbons and bromofluorocarbons are the major depleters of the ozone layer. The chlorine and bromine separate from the CFCs (chlorofluorocarbons) and destroy the ozone molecules.
What human made chemical is destroying the ozone layer?
Water vapor. Chlorofluorocarbons. Insecticides.See "What is causing the depletion of the ozone layer?" in the "Related questions" section below.
