CFCs
it is commonly known as freon.
They come from various sources. AC's, deodorants etc are some examples.
CFC's react with ozone. They decompose it to deplete the layer.
United States is the lead producer of CFC's. These deplete the ozone layer.
CFC's are very reactive chemicals. They react with ozone to decompose it and deplete it.
Yes, CFCs can destroy the ozone layer. They react with ozone present in ozone layer and decompose it.
CFC's may be harming the ozone layer. They do it by depleting the ozone, decomposing into single atoms.
From the presence of the element fluorine, the molecules are spelled chlorofluorocarbons (CFCs).(*fluorine shares this "UO" spelling with the words fluorescent and fluorescence)
There are many gases that cause "greenhouse effects". Water Vapour Carbon dioxide Methane Nitrous Oxide Ozone Chloroflourocarbons (CFC's) are just a few.
The propellant is usually Butane, which took over from ChloroFlourocarbons, to save the ozone layer.
it is because when they deplete the ozone layer they attributes to the increasing of the ozone hole and allow the ultraviolet rays to reach the earth. due to ozone depletion, not only temperature increases but also level of water that result into floods.
Although today's aerosol hairspray does not contain chloroflourocarbons, there are still some which are more environmentally friendly available in the USA currently. Pantene Pro-V is one of the brands listed as being environmentally friendly.
