What do CFCs break down into?

Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules. When sunlight returns in the spring, the chlorine begins to destroy ozone.

How are CFCs formed?

CFCs and HCFCs are usually produced by halogen exchange starting from chlorinated methanes and ethanes.

What are chlorofluorocarbons short answer?

Chlorofluorocarbon(CFC) is any of various halocarbon compounds consisting of carbon, hydrogen, chlorine, and fluorine. CFC were once used widely as aerosol propellants and refrigerants. Chlorofluorocarbons are believed to cause depletion of the atmospheric ozone layer.

What are chlorofluorocarbons?

Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.

Why are chlorofluorocarbons harmful?

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.

What are examples of chlorofluorocarbons?

Chlorofluorocarbons are refrigerants that contain chlorine. They have been banned since the beginning of the 90’s because of their negative environmental impacts. Examples of CFCs are R11, R12 and R115.

Are CFCs toxic to breathe?

Inhaling CFCs Inhalation of CFCs can also disturb the heart rhythm, which can lead to death. Exposure to large amount of CFCs could potentially cause asphyxiation, according to the Centers for Disease Control and Prevention.
