They were already present in nature. They were just discovered by scientists.
Some common gases that contain oxygen include carbon dioxide (CO2), ozone (O3), and nitrogen dioxide (NO2). These gases contain oxygen in various chemical compositions and play important roles in atmospheric processes.
The atomicity of oxygen in ozone is 3. This means that each molecule of ozone contains three oxygen atoms.
Most of the oxygen in the atmosphere is O2, at any altitude. It's true that ozone molecules, O3, are heavier than regular oxygen gas O2, but mixtures of gases do not layer out by mass or density -- they thoroughly mix. In the stratosphere, however, the higher levels of ultraviolet radiation produce fresh ozone from diatomic oxygen, so ozone concentrations remain higher in this region.
Ozone consists of three oxygen atoms (symbol is O3).
Ozone can be separated into oxygen by using ultraviolet light or by heating it to a high temperature, which breaks the ozone molecule into oxygen molecules. This process is called ozone cracking and it helps to convert ozone back into oxygen.
The ozone layer is comprised of a number of gases, in proportions similar to the rest of the atmopshere. It contains about 78% nitrogen, 21% oxygen, the usual complement of trace gases, and about 0.0009% peak ozone in the lower stratosphere (the ozone layer). So no, it is not entirely oxygen, nor is it entirely ozone. But it does contain both gases.
Ozone is destroyed by the CFC gases. CFC converts ozone to oxygen.
Ozone on reaction with CFC gases decomposes into oxygen. It is responsible for ozone layer depletion.
There is only one gas. Ozone which is a type oxygen.
Ozone hole is constantly changing due to release of CFC gases. They convert ozone to oxygen.
The gases that come from humans that deplete ozone are many. CFC's are one of the most dangerous of them.
Chlorofluorocarbons (CFCs) and halons are particularly damaging to the ozone layer. These gases break down ozone molecules in the stratosphere, leading to ozone depletion. Reducing the use and production of these gases has been a key strategy in protecting the ozone layer.
Ground level ozone is one kind of gas. Ozone. Three gases are required make ozone in the presence of violet or more energetic light from the Sun: oxygen, NOx and VOC (unburned fuel).
CFC gases are responsible for the depletion of ozone layer. CFC convert ozone to oxygen and make it useless for the absorption of UV radiation.
The hole in the Ozone Layer is a region of the atmosphere where the concentration of ozone is significantly depleted. It is primarily located over Antarctica. This depletion is caused by the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances into the atmosphere.
Ozone depletion is depletion of ozone is in atmosphere. CFC gases which are pollutants are responsible for the depletion of ozone layer. CFC convert ozone to oxygen and make it useless for the absorption of UV radiation.
Oxygen when came in contact with UV broke down. It then reacted with more oxygen to form ozone.
