Question

What would happen if all the oxygen present in the environment is converted to ozone?
A. We will still be able to breathe
B. It will be poisonous and will kill living forms.
C. Ozone is not stable, hence it will be toxic.
D. It will help harmful sun radiations to reach earth and damage many life forms.

Answer 1

Hint: The ozone layer is present above the earth's surface formed by the combination of three oxygen atoms. The ozone layer is present in the stratosphere region and is also known as the ozonosphere. The ozone molecules in the ozone layers degrade under the action of UV rays that come from the sun and form molecular oxygen and the layer of the ozone is degraded.

Complete answer:
Exposure to the ozone gas irritates and inflames the lining of the respiratory tract hence can be considered as a highly toxic gas to be inhaled by humans or any living beings resulting in death.
Hence option B is the correct answer.

If all the oxygen present on the earth is converted to ozone then no oxygen will be present for breathing,
hence option A is incorrect.

Ozone is an unstable gas and will degrade into three molecules of oxygen.
Hence the option C is incorrect.

The ozone layer present above the earth's surface prevents us from the UV rays of the sun hence if more ozone will be formed the ozone layer depletion can be overcome serving greater protection to the earth.
Hence option D is incorrect.

Note:
The symptoms of the toxicity of ozone include irritation in the eyes, nose, and throat region, while some can also experience shortness of breath, cardiac symptoms, chest pain, and wheezing. The lung function of the individual can be changed with the feeling of tiredness and lacking energy, extreme cases can lead to death.
