(i) Ozone is not responsible for green house effect . (ii) Ozone can oxidise sulphur dioxide present in the atmosphere to sulphur trioxide. (iii) Ozone hole is thinning of ozone layer present in stratosphere. (iv) Ozone is produced in upper stratosphere by the action of UV rays on oxygen.
Which of the following is correct about ozone?
Answer (d) Stratospheric ozone protects us from UV radiations .
Which of the following is wrong about ozone?
(i) Ozone is not responsible for green house effect . (ii) Ozone can oxidise sulphur dioxide present in the atmosphere to sulphur trioxide. (iii) Ozone hole is thinning of ozone layer present in stratosphere. (iv) Ozone is produced in upper stratosphere by the action of UV rays on oxygen.
Which layer of the ozone is bad?
“Bad” ozone is found in the troposphere , the layer nearest the ground. Tropospheric ozone is a harmful pollutant which forms when sunlight alters various chemicals emitted by humans. “Good” ozone forms in the stratosphere, the next higher layer where some jet planes fly.
Is ozone is responsible for greenhouse effect?
Ozone is technically a greenhouse gas , but ozone is helpful or harmful depending on where it is found in the earth’s atmosphere. ... The protective benefit of stratospheric ozone outweighs its contribution to the greenhouse effect and to global warming.
What is the bond angle of ozone?
| Name of molecule Ozone (O3) | No of Valence Electrons in the molecule 18 | Hybridization of O3 sp2 hybridization | Bond Angles 116 degrees | Molecular Geometry of O3 Bent |
|---|
Is ozone diamagnetic in nature?
Properties of Ozone
Ozone is diamagnetic , which means that its electrons are all paired. In contrast, O 2 is paramagnetic, containing two unpaired electrons.
What is ozone layer?
The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
What is ozone hole short answer?
The term ‘ozone hole’ refers to the depletion of the protective ozone layer in the upper atmosphere (stratosphere) over Earth’s polar regions. ... Polar stratospheric clouds create the conditions for drastic ozone destruction, providing a surface for chlorine to change into ozone-destroying form.
Is ozone is highly reactive?
Ozone is a highly reactive molecule formed by atmospheric transformation of precursors in the presence of sunlight. Because of its reactive nature, ozone does not penetrate the body beyond the lungs.
What are the 2 types of ozone?
Ozone or “O3” is a colorless gas composed of three atoms of oxygen (O3). There are two types of ozone, both “good” ozone and “bad” ozone .
What is a bad ozone?
The layer closest to the Earth’s surface is the troposphere. Here, ground- level or “bad” ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation . It is a main ingredient of urban smog.
Can you smell ozone?
Ozone has a distinctive smell that humans can detect even in small concentrations — as few as 10 parts per billion. Here are some of the ways the smell of ozone is described: Metallic. Like a burning wire.
How does ozone act as a greenhouse gas?
At top of stratosphere, 30 miles high, ozone absorbs most of the harmful ultraviolet radiation from the Sun. At the top of the troposphere, 12 miles high, ozone acts as a greenhouse gas, trapping heat . In the middle of the tropsohere, ozone helps clean up certain pollutants.
Why is ozone considered a greenhouse gas?
Tropospheric (near the surface) ozone is a powerful greenhouse gas , even in trace amounts. Strataspheric ozone or the ozone layer is opaque to UV rays coming in and it’s opaque to IR rays going out so it has both warming and cooling effects.
Why is nitrogen not a greenhouse gas?
Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light . These molecules are invisible because when you stretch one, it doesn’t change the electric field. ... In general, symmetrical molecules with only two atoms are not greenhouse gases.
