Name the regions of the atmosphere where global warming and ozone depletion phenomenon occur.

Name the zone of the atmosphere where ozone layer is present.

Ozone depletion is occurring due to

Name the different regions of the atmosphere alongwith their altitudes and temperature ranges.

The chemistry of corrosion of iron is essentially an electrochemical phenomenon. Explain the reactions occurring during the corrosion of iron in the atmosphere. Suggest two materials other than hydrogen that can be used as fuels in fuel cells. The molar conductivity of 0.025 "mol L"^(-1) , methanoic acid is 46.1 scm^(2)"mol"^(-1) . Calculate its degree of dissociation and dissociation constant.

Global warming of the atmosphere due to trapping of long infrared radiations is called :

What are the reactions involved for ozone layer depletion in the atmosphere ?

How does Nitric oxide emitted from the exhaust of Supersonic jet aeroplanes deplete the ozone layer in the upper atmosphere ?

Chlorofluroocarbons are responsible for ozone depletion but do not play any role in global warming.
