What are the gasses in the ozone layer?

Ozone is a gas made up of three oxygen atoms (O3). It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Ozone protects life on Earth from the Sun’s ultraviolet (UV) radiation.

Which gas affects most ozone layer?

Bromine is many times more effective at destroying stratospheric ozone than chlorine. See ozone depleting substance. (used in fire extinguishers), and methyl chloroform. Methyl chloroform is used as an industrial solvent.

How is ozone gas made?

Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere.

Which gas does not harm ozone layer?

F-gases include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). These gases do not deplete the ozone layer, but they are greenhouse gases.

Does co2 affect the ozone layer?

Carbon dioxide has no direct effect on ozone, unlike CFCs and HFCs.

What is ozone gas used for?

It is used for purifying air and drinking water, in industrial waste treatment, oils, bleaching and waxes, and to make other chemicals. Some examples of workers at risk of being exposed to ozone include the following: Outdoor workers in areas with high levels of ozone.

Which gas does not affect ozone layer?

So, the correct answer is ‘Cl2’.

Where is ozone gas found?

the stratosphere
Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth’s surface (see the figure below). Ozone is a molecule that contains three oxygen atoms. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere.

How is ozone gas formed?

What is HFC and CFC?

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun.

Is CFC a greenhouse gas?

HFCs, CFCs and HFCs are a subset of a larger group of climate changing gases called greenhouse gases (GHGs). Taken together greenhouse gases are expected to warm the planet by 2.5 to 8 degrees Fahrenheit by the end of century.

Which of the following gas is depleted to the ozone gas?

Both chlorine and bromine contribute significantly to overall ozone depletion.

Does CO2 affect the ozone layer?

Which gas is maximum in atmosphere?

Nitrogen (N2)
The most abundant naturally occurring gas is Nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas Argon (Ar) is the third most abundant gas at . 93%.
