What is a dangerous substance that depletes the ozone layer when released to the atmosphere?
Chlorofluorocarbons also called Freons
These chemicals were developed by General Motors in the late 1920s as "safe nontoxic" refrigerants to use in home refrigerators instead of the highly dangerous and toxic refrigerants then in use.
By the 1960s these chemicals were in use nearly everywhere, including as the propellant in all aerosol cans (e.g. hairspray, paint, deodorant).
By the late 1970s however it had been demonstrated that the chlorine in these chemicals could rapidly destroy the ozone in the ozone layer that blocks much of the UV light before it reaches the surface of earth, and it was decided to phase them out and find different chemicals for these uses.
These chemicals can now no longer be purchased, except when they have been recycled and are intended for use in old systems that cannot operate with the newer chemicals. Eventually these old systems will be replaced with new ones and the demand for recycled chlorofluorocarbons will cease and the loss of ozone in the ozone layer will stop and it will recover. But this will require decades.

What depletes ozone in stratosphere?
Chemicals such as chlorofluorocarbons (CFCs) and other ozone-depleting substances released into the atmosphere can break down ozone molecules in the stratosphere. These chemicals react with ozone, causing it to break apart and reduce the overall levels of ozone in that layer of the atmosphere.
What is a gas released into the atmosphere by combustion called?
Carbon dioxide (CO2) is the gas released into the atmosphere by combustion of fossil fuels.
How does CFC from the fridge damages the ozone layer?
CFCs released from refrigerators reach the upper atmosphere, where they break down ozone molecules. This breakdown leads to a reduction in the protective ozone layer, allowing harmful UV radiation to reach the Earth's surface. This can have severe consequences for human health and the environment.
How far does cfc cause ozone depletion?
CFCs (chlorofluorocarbons) are a major contributor to ozone depletion. When released into the atmosphere, they break down ozone molecules, particularly in the stratosphere. This destruction of ozone allows more harmful UV radiation to reach the Earth's surface, posing risks to human health and the environment.
What products in aerosol form are still dangerous to the ozone?
Products such as spray paints, hair sprays, and some aerosol cleaners that contain chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs) are still dangerous to the ozone layer. When released into the atmosphere, these chemicals can deplete the ozone layer, leading to harmful effects on the environment.
Is a 2.5pH level dangerous?
When the pH level of a substance drops down to 2.5, at that point, the substance is considered to be dangerous. When the pH level of a substance drops down to 2.5, at that point, the substance is considered to be dangerous.
What depletes ozone in stratosphere?
Chemicals such as chlorofluorocarbons (CFCs) and other ozone-depleting substances released into the atmosphere can break down ozone molecules in the stratosphere. These chemicals react with ozone, causing it to break apart and reduce the overall levels of ozone in that layer of the atmosphere.

What is a substance that store energy released by mitochondria?
ATP is a substance that stores energy released by mitochondria.
What substance are thought to be main sources of chlorine radicals in the atmosphere?
The main sources of chlorine radicals in the atmosphere are man-made chlorofluorocarbons (CFCs) and other halocarbons. These compounds are released into the atmosphere from activities such as refrigeration, air conditioning, and aerosol propellant use. Once in the atmosphere, sunlight breaks down these compounds, releasing chlorine radicals that can contribute to ozone depletion.
When was Dangerous?
Dangerous Liaisons was released on 12/21/1988.
Water carbon and nitrogen are released back into the atmosphere during what?
Water vapor is released back into the atmosphere through the process of evaporation. Carbon is released back into the atmosphere through the process of respiration and combustion. Nitrogen is released back into the atmosphere through the process of nitrogen fixation by bacteria.
