There is no limit to the number of ozone molecules the chlorine from a CFC molecule can destroy, or how long it will stay "up there". Over time, chlorine will find something else to bond to and leave the ozone layer. The hope is that once we stop delivering such compounds to the atmosphere, that can eventually happen.
Right now estimations vary from 1 : 10,000 to 1 : 1,000,000 before it leaves the ozone layer.
Chlorine from CFCs are photo-excited into acting like catalysts. Catalysts participate in a reaction (such as the decay of ozone), but are unchanged when the reaction is carried to completion. So the only way for the effect of chlorine to be dissipated is by competing reactions that take it out of the area and / or change its nature to be unreactive or one-time reactive.
Chlorine is a catalyst for ozone destruction. It is restored to it initial state once it has completed its reaction, so it can destroy ozone molecules again. Until some other competing process ties CFC up in some more permanent way, it will keep destroying ozone.
It should be noted that most chlorine in the atmosphere is not from CFC's, but from naturally occurring water vapor off of our oceans.
So there is no "hard coded" limit to its ozone destructive capabilities. We just have to wait until it is removed by time.
None. Ozone is made from oxygen, so encountering an oxygen (or nitrogen) molecule is no big deal. Water vapor, or a chlorine or oxygen atom is something else again. The effect there is 1:1 (or more in the case of chlorine) ozone molecules destroyed.
Ozone doesn't destroy chlorine. Chlorine atoms in the ozone layer with continue to effect ozone molecule, after ozone molecule until it finds something else to attach to, or falls below the ozone layer, back towards the earths suface.

CFC molecules react with ozone. They decompose the ozone molecules.
It is believed that 1 molecule of CFC can destroy about 100,000 molecules of ozone. It decomposes ozone into oxygen molecule and oxygen and nascent oxygen.
A single chlorine molecule can destroy upto 100,000 molecules of ozone. It is because of the chain reaction started by chlorine.
The CFC molecules are man made chemicals for refrigeration. The molecules on reaction release 2 gases. These gases are Chlorine and Fluorine.
oxygen and fluoride
No, the chlorine and other chemicals in CFCs (chlorofluorocarbons) destroy the ozone molecules and weaken the ozone layer.
The human made chemicals that destroy the ozone are CFCs. These CFCs are ones that decompose the ozone molecules.
3 sources of CFC's are:Aerosol SpraysRefrigeratorsAir conditioners.
They react with ozone. Decompose it and cause ozone depletion.
The humans destroy ozone by usng CFCs. These are compounds which react with ozone to deplete it.
No, the chlorine and other chemicals in CFCs (chlorofluorocarbons) destroy the ozone molecules and weaken the ozone layer.
The human made chemicals that destroy the ozone are CFCs. These CFCs are ones that decompose the ozone molecules.
CFCs (chlorofluorocarbons) destroy ozone in the ozone layer.

Chlorine and bromine separate from the CFCs (chlorofluorocarbons) and destroy the ozone molecules. The chlorine and bromine atoms are not changed, so they continue destroying ozone. One chlorine atom can destroy up to 100,000 molecules of ozone during its lifetime in the atmosphere.
They react with ozone. Decompose it and cause ozone depletion.
See "What is causing the depletion of the ozone layer?" in the "Related questions" section below.
The humans destroy ozone by usng CFCs. These are compounds which react with ozone to deplete it.
Yes, CFCs can destroy the ozone layer. They react with ozone present in ozone layer and decompose it.
As the CFCs are carried to Antarctica there is a big ozone hole. Chlorine and bromine atoms from CFCs (chlorofluorocarbons) separate and destroy ozone molecules, but remain active for several years continuing their destruction. So if more CFCs will be produced in the world more CFCs will be carried to Antarctica by the polar winds and more depletion and the rate of depletion will exceed the rate of formation of ozone molecules resulting in the expansion of ozone hole over Antarctica.
The pollutant that is beleived to be causing damage is CFC. It is a synthetic chemical that might lead to ozone depletion.
They are carried by westerlies. They destroy the ozone.
