What are chlorine atoms in the stratosphere?
They break down ozone into oxygen atoms.
How the chlorine atoms are formed in the ozone layer?
CFC's i.e Chloro Fluorocarbon which are released from deodorants, refrigerants are carried upwards towards the atmosphere where in presence of the high energy ultraviolet rays these break down into molecules of chlorine and fluorine molecules which further deplete ozone.
Which element has the largest atomic radius out of fluorine chlorine or bromine?
Bromine is farther down the group and has more electron shells, making it an element with a lager atomic radius.
How are humans contributing to the problem?
Humans are doing things that make more ozone in the troposphere, where it damages plants, animals and humans. Primarily, this is done by combusting fuels in air, which produces NOx. NOx can be converted into ozone, and either is bad. Humans are doing things that make for less ozone between us and Earth's surface, which lets more UV-B reach Earth's surface, damaging the DNA of all surface life on Earth. There are many human-sourced causes, including adding water vapor to the air, warming the thermocline that should keep water vapor out of the ozone layer, and adding chemicals that contain chlorine and bromine to the air (they are so stable only the intense radiation of the ozone layer can break them down, and they help destroy ozone then).
What is the hazard associated with using both chlorine and bromine to sanitize a pool?
Yes, bromine levels should be kept between 3-5. When they get higher you can add neutralizer to bring it down. High bromine levels will dry out your skin, bleach your suits, and it is unhealthly to swim in.
Why CFC break down chlorine atom?
CFC's are unstable. they break down to deplete ozone.
What are chlorine atoms in the stratosphere?
They break down ozone into oxygen atoms.
How does bromine react with ozone?
Bromine is oxidized by ozone, so the ozone is broken down.
How is ozone produced in the stratosphere depleted?
Ozone depletion in the stratosphere is primarily caused by the release of certain chemicals known as ozone-depleting substances (ODS), such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). These chemicals contain chlorine and bromine atoms that are released into the atmosphere through human activities. When these molecules reach the stratosphere, they are broken down by ultraviolet (UV) radiation, releasing chlorine and bromine atoms that can then catalytically destroy ozone molecules. This process leads to the depletion of ozone in the stratosphere.
Which moleculer damage ozone layer?
Lots of different molecules can damage the ozone layer.Water vapor is the biggest one, and anything that contains chlorine or bromine in the molecule will also damage ozone.
What is the advantage of ozone over chlorine in public pools?
Ozone is rarely used as a primary pool treatment. If ozone is used, bromine is the steriliant of choice, since you only need to add it a few times a year (lower vapor pressure than chlorine). Ozone reactivates the bromine, and is destroyed in the filter. Ozone is hazardous for lungs. Using ozone tends to reduce the THM and HAA that chlorine can form in pool water. It can also reduce the amount of water "blown down", since fewer chemicals need to be used. And fewer chemical deliveries. When you turn power off, ozone is gone. Chlorine stays, and stays hazardous.
How chlorofluorocarbon affect ozone layer?
It turns ozone into oxygen gas, which destroys the ozone layer.
Are CFC's good to the ozone layer?
No...CFC's are the ones which are bad for ozone layer i.e. they deplete it. CFC are actually Chlorine and Florine containing compounds which when come in contact with harmful ultraviolet rays and break down into chlorine and fluorine and thus react with ozone to form compounds which deplete ozone.
How is ozone layer depleted in nature?
Ozone depletion is the process where ozone holes are created in the ozone layer. It is caused due to the action of chloro-floro-carbons on the ozone molecule to break it down to oxygen.
What layer of atmosphere do the CFC's destroy?
When CFCs are present in the stratosphere they reacted on by ultra violet light to release a chloride ion. The ion breaks down an ozone molecule to create an oxygen molecule and ionic oxygen. The ionic oxygen releases more chloride ions to break down more ozone and CFCs The end result is the ozone is converted to oxygen quicker than natural processes can replace it
Gases will react with the ozone layer and break it down?
CFC's are the gases that react with ozone to break it down. They deplete the ozone.
What if ozone started to break down?
Ozone has started to break down. It has caused UV to enter the earth's surface.
