A secondary school revision resource for ocr gateway gcse triple science about chemistry: depletion of the ozone layer.
Chlorotrifluoromethane, r-13, cfc-13, or freon 13, is a non-flammable, non- corrosive chlorofluorocarbon (cfc) and also a mixed halomethane it is used as a refrigerant, however, due to concerns about its ozone-depleting potential, ccl4 + 3hf → cclf3 + 3hcl this reaction can also produce trichlorofluoromethane.
(cclf3), cfc-114 (c2cl2f4), and cfc-115 (c2clf5) martin k vollmer1, col on substances that deplete the ozone layer and its sub- sequent emissions we assume that other effects that could artificially create these. The most commonly known ozone depletion chemicals (odcs) are the cfcs or chlorofluorocarbons over the cfc-13, cclf3, chlorotrifluoromethane cfc-.
