CFCs have been replaced by HCFC swhich have less environmental impact. Propane , nitrogen, and air are now routinely used in many applications where CFCs were used as propellants in aerosol and refrigerant containers. Freon (a fire fighting chemical) is still widely used but with stricter controls on losses in non fire situations.
What else can I help you with?
What can each one of us do to save the ozone layer?
In order to save the ozone layer,we have to curb the use of CFCs. These CFcs are the ones that help in the destruction of ozone.
How do cfcs affect air heath?
By the CFCs being sorced into the air, the sun is Breaking them down into the earth.
What kind of effect do CFCs - chlorofluorocarbons - have on the atmosphere?
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.
What can companies that now produce CFCs do to replace money lost when CFCs are banned?
Make something else BUT this time check that the products they are making are not harmful. They aught also to pay towards the environmental harm that CFCs have caused.
What human-made gas can affect the Earth's ozone layer?
CFCs
What class of molecules has CFCs replace?
CFC's are ozone depleting substances. HCFC's are an alternative to CFC's.
What effect do CFCs have on the Earth's stratosphere?
CFCs (Chlorofluorocarbons)What type of substance is it?CFCs are a class of man-made chemicals, generally non-toxic, non-flammable, chemically unreactive, colourless liquids or gases that evaporate easily. They are a group of ozone depleting substances. They damage the Earth's ozone layer, which protects the earth's surface from harmful ultra-violet radiation. CFCs are also powerful greenhouse gases which contribute to global warming.How is it released?Release to the atmosphere is primarily from CFC-containing aerosols, refrigeration equipment and some foams. There are no natural sources of CFCs.
Do chlorofluorocarbons helps create water pollution?
No, CFCs are a type of halogenated hydrocarbon in which both chlorine and fluorine atoms replace some of the hydrogen atoms. This has no effect on water, but it does bring about a thinning of the Earth's ozone shield. If you didn't know, thinning the Earth's ozone shield is bad.
Which element in chlorofluorocarbons (cfcs) are responsible for destroying the earth's ozone layer?
Chlorofluorocarbons (CFCs) contain chlorine and bromine atoms, which are primarily responsible for the destruction of the Earth's ozone layer. When CFCs are released into the atmosphere, ultraviolet (UV) radiation breaks them down, releasing chlorine atoms. These chlorine atoms then catalyze the breakdown of ozone (O₃) molecules, leading to the depletion of the ozone layer that protects the Earth from harmful UV radiation.
Why save earth?
save earth because we are living on it.
What substitutes for CFCs came into being after scientists discovered that CFCs were harming the atmosphere?
After discovering the harmful effects of CFCs on the atmosphere, scientists developed substitutes such as hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) to replace CFCs in various applications like refrigeration and air conditioning. These alternatives have lower ozone-depleting potential and are less harmful to the environment than CFCs. Additionally, advancements in technology have led to the development of more environmentally friendly alternatives like natural refrigerants such as ammonia, carbon dioxide, and hydrocarbons.
Which substance is considered to be a factor affecting Earth's ozone layer?
Chlorofluorocarbons (CFCs) are substances that have been identified as a major factor affecting Earth's ozone layer. When released into the atmosphere, CFCs break down and release chlorine atoms that can destroy ozone molecules.
