Ozone in the stratosphere is produced by the help of uv radiations. It protects us from harmful uv radiations.
Explain with chemical equation, the destruction of ozone by chloroflurocarbons causing ozone hole

Ozone in the stratosphere is produced by the help of ultraviolet radiations. It protects us from harmful ultraviolet radiations. a) Write equation for the formation of ozone in stratosphere.

Green chemistry means such reactions which (1)Produce colour during reactions. (2)Reduce the use and production of hazardous chemicals. (3)Are related to the depletion of ozone layer (4)Study the reactions in plant

Ozone acts as a shield for absorbing ultraviolet radiations from the sun. Name the region of atmosphere where ozone is seen.

Which of the following statement/s is /are wrong: (i) Nitric oxide and chlorofluoro carbons are two main ozone depleting agents. (ii) In the stratosphere CFCs undergo photochemical decomposition to produce chlorine free radical which destroy ozone layer. (iii) Ozone hole has mainly been observed in the stratosphere over Antarctica. (iv) Innon polar regions of the stratosphere, chlorine monoxide free radicals combine with NO_(2) and chlorine free radicals combine with methane, as a result the chain reaction causing ozone depletion stops v. Northern hemisphere is free from ozone depletion

As a result of stratospheric pollution the ozone layer is destructed. Write a harmful effect of ozone layer depletion.

Ozone acts as a shield for absorbing ultraviolet radiations from the sun. Write the unit used to measure ozone layer.
