Hi,
Halon is a liquefied, compressed gas that stops the spread of fire by chemically disrupting combustion.Halon is an extraordinarily effective fire extinguishing agent, even at low concentrations. A key benefit of Halon, as a clean agent, is its ability to extinguish fire without the production of residues that could damage the assets being protected.
I know a site named Halon.us which buy damaged halon extinguisher from public.
Halons are a class of chemical compounds that were historically used in fire extinguishing systems because of their effectiveness at suppressing fires. However, they have been largely phased out due to their negative impact on the environment, specifically their harmful effects on the ozone layer.
Halocarbons are a class of organic compounds containing covalently bonded fluorine, chlorine, bromine or iodine. Naming halocarbons is based on the name of the parent hydrocarbon chain and the halocarbons are simply named as substituents. For example, (using skeleton chains - absence of other hydrogen atoms
(a) C-C-C-C-F is fluorobutane (as the fluorine is attached to carbon #1 of the butane chain;
F
I
(b) C-C-C-C-C-F is 1,3,4-trifluoropentane
I
F
(keeping the numbers as low as possible and identifying all carbons that the substituents are attached to).
hope this helps

What is the concentrations that have been reduced as a result of the Montreal protocol?
The Montreal Protocol has led to the reduction of concentrations of ozone-depleting substances such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons. These substances have been phased out gradually to protect the ozone layer and mitigate the risk of harmful effects on human health and the environment.
What allotrope of this element is being depleted from earth's stratosphere?
The allotrope of oxygen being depleted from Earth's stratosphere is ozone (O3). Ozone depletion is primarily caused by human-made chemicals like chlorofluorocarbons (CFCs) and halons, which break down ozone molecules in the atmosphere. This depletion leads to the formation of the ozone hole, allowing more harmful ultraviolet (UV) radiation to reach the Earth's surface.
If the world was to ban from cfc's who would this law effect?
A ban on CFCs would primarily affect industries that use these chemicals as refrigerants, solvents, or in the manufacturing of foam products. However, it would benefit the environment by reducing ozone depletion and global warming potential associated with CFC emissions.
What are the primary greenhouse gases released to the atmosphere by humans?
The primary greenhouse gases released by humans are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These gases contribute to the greenhouse effect, leading to global warming and climate change.
What is the big hole created by the hazardous gases in the ozone layer?
The big hole in the ozone layer is a depletion of ozone gas, primarily caused by human-produced chemicals like chlorofluorocarbons (CFCs) and halons. This hole allows more harmful ultraviolet (UV) radiation from the sun to reach the Earth's surface, which can lead to increased health risks for humans and other living organisms. Efforts to reduce the production and use of ozone-depleting substances have helped to slow down the depletion of the ozone layer.
Do halons and CFC's both destroy ozone in the stratosphere?
Yes they do. Halons and CFC's both destroy ozone.
Do halons contain halogens that are highly reactive with oxygen?
Yes, halons contain halogens such as bromine, fluorine, or chlorine, which are highly reactive with oxygen. This property allows halons to be effective in fire suppression by chemically interrupting the combustion process. However, the use of halons has been largely phased out due to their ozone-depleting properties.
Which chemical are controlled by the Montreal Protocol?
Halons
How halons causes ozone depeletion?
Halons contain chlorine and bromine atoms which, when released into the atmosphere, can react with ozone molecules. These reactions lead to the breakdown of ozone molecules, causing ozone depletion. Halons are potent ozone-depleting substances and are now heavily regulated under international agreements to help protect the ozone layer.
Why is halon harmful for ozone layer?
Halons are harmful for ozone. They also react with ozone to deplete it.
What do Halons and CFC s do to the ozone A inhibit ozone formation B cause ozone formation in the troposphere C destroy ozone in the stratosphere D cause excess ozone formation in the stratosphere?
Halons and CFC s both destroy ozone in the stratosphere.
Halons contain halogens which are highly reactive with oxygen?
Yes, halons contain halogen atoms that are highly effective at disrupting chemical reactions involving oxygen, making them effective in extinguishing fires by interrupting the combustion process. However, halons contribute to ozone depletion and are no longer widely used due to their harmful environmental impact.
How much fuel does a cat 966 use per hour?
7 halons per hour
What are halans causing ozone depletion?
Halons are a class of chemical compounds that contain bromine and chlorine, which are known to deplete the ozone layer. When halons are released into the atmosphere, they can break down ozone molecules, leading to a reduction in the concentration of ozone in the stratosphere. This depletion of the ozone layer can have harmful effects on human health and the environment by allowing more harmful UV radiation to reach the Earth's surface.
Which pollutants affect the ozone layer?
Chlorine and bromine in the man-made gases like halons and freons (CFCs).
What type of things destroy the ozone?
All the things containing halons destroy it. Chlorine, Fluorine etc are the destroying elements.
What are the chemicals that are being blamed for the destruction of the ozone layer?
one of the chemicals that are being blamed for the destruction of the ozone layer are chlorofluorocarbons.and the halons
