Well....ozone is a chemical itself.
It is O3 but as far as the chemical composition of "air," that is several compounds.
Air is N2 O2 CO2 mostly....with a few others that are a very small percentage.
Oxygen atom is the component of ozone layer. It is made of three atoms of oxygen.
There are no components of ozone layer. Just a single layer.
The ozone layer is a complete layer. It does not contain any other components.
The ozone layer has no components. It is a layer of relatively normal atmosphere, like the rest of the atmosphere... but the ozone is increased from near zero to 9 ppm.
CFC's react with ozone. They deplete the ozone layer.
Ozone layer is being depleted. The chemical reactions involve depleting of ozone into oxygen.
Ozone layer has undergone various changes. These are the depletion of ozone molecules.
Ozone is a very important gas and chemical for it. In the ozone layer, it acts as the protective layer of the earth.
The ozone layer is a layer of ozone gas. The layer is present in stratosphere. It helps in protecting earth.
Chlorofluorocarbons damage the protective ozone layer.
There are two components. Man made substances and natural substances which deplete ozone.
CFC is destroying ozone. It is the industrial chemical.
