Freon is a name trademarked by DuPont for a line of CFC and HFC refrigerants which they manufacture. Other manufacturers make these same refrigerants, but cannot call them Freon, as DuPont has exclusive rights to the name. The common name depends on the exact refrigerant you had in mind, as different types of AC systems use different refrigerant.
Please see the related questions below. Not all "freons" contain either chlorine or bromine, so your question has no answer. Chlorine or bromine is required in the molecule for "freons" to be an ozone depleter.
Freons deplete ozone. They react with ozone to deplete it.
Short answer- you don't. You must be licensed and have special equipment to handle older freons. If you don't know how, you don't have the license, and you will not be allowed to buy the older Freon. BTW, the older Freons like R-12 are incredibly expensive.
Yes, freon can be toxic when inhaled, causing symptoms like nausea, dizziness, and respiratory issues. Prolonged exposure to high concentrations can be dangerous to human health and the environment as well.
The anagram is chlorofluorocarbons (CFC's, e.g. some freons).
Chlorine and bromine in the man-made gases like halons and freons (CFCs).
The main damage to the ozone layer was caused by freons, with the layer thinning to such an extent over Antarctica that it was referred to as the'ozone hole'. Fortunately, the industrial use of freons was banned, perhaps just in time, and the ozone layer is recovering. Alternative fuels are unlikely to affect this recovery.
never mix these freons together---- very dangerous
Freons and other gases were used in the past. Today the most used gas is the tetrafluoromethane (code R134a).
ODS stands for Ozone Depleting Substances. These include freons, CFC's etc.
The common name is horsetails.
The common name for limestone is simply "limestone".
