WebThe ozone gradually returns to normal levels by late November. The new results reported by the JPL researchers show unusually large amounts of chlorine nitrate, one of two molecular forms in which chlorine released from chlorofluorocarbons is stored in the stratosphere. The other reservoir is hydrochloric acid. WebClO + O = Cl + O2. The industrial production of CFCs started in the 1920’s, causing an average reduction of the ozone layer of 3 per cent. Fortunately, chlorine has “natural enemies” as well, such as methane (CH4). Thanks to them, the natural ozone layer could recover over 50 years, as long as CFCs are no longer used on a global level.
How Does Chlorine Affect the Ozone Layer? Sciencing
WebFree chlorine atoms then react with ozone molecules, taking one oxygen atom to form chlorine monoxide and leaving an ordinary oxygen molecule. The destruction of ozone, … WebAug 25, 2016 · Yes - CFCs interact with and break down ozone. CFCs are lifted by buoyancy into the stratosphere, where they are broken up by the sun's ultraviolet radiation (1), and the chlorine then reacts with ozone (2), with equation: Then that chlorine monoxide reacts with atmospheric oxygen: (4) and so the chlorine can go on to damage more ozone, again ... binod bhattarai

WebBombarded by the sun's ultraviolet energy, CFC molecules break up and release chlorine atoms. Free chlorine atoms then react with ozone molecules, taking one oxygen atom to form chlorine monoxide and leaving an ordinary oxygen molecule. Image above: Ozone destruction begins when chlorine and oxygen combine. Credit: NASA Webrine monoxide (ClO) and bromine monoxide (BrO), and chlorine and bromine atoms (Cl and Br). A large fraction of available stratospheric bromine is generally in the form of BrO, whereas usually only a small fraction of strato-spheric chlorine is in the form of ClO. In polar regions, the reservoirs ClONO 2 and HCl undergo a further conver- WebOct 23, 2024 · However, scientists have discovered that certain chemicals react with UV radiation in the stratosphere, which causes them to break apart and release chlorine or bromine atoms. These atoms, in turn, destroy ozone molecules. Ozone-depleting substances ( ODS ), which include chlorofluorocarbons (CFCs) and hydrofluorocarbons daddy books for father\u0027s day
