1. Carbon dioxide is the constituent of air which is present 0 . 02 % . It is consumed by plants during photosynthesis. 2. Argon in the air is inert or unreactive. It is mainly used in electric bulbs. 3. Oxygen is the constituent in air which is non-combustible, but supports combustion. It is also required for respiration. 4. Sulphur dioxide in air is responsible for acid rain. On reaction with water, it forms sulphuric acid. 5. The main gas present in air is nitrogen after which comes oxygen. Nitrogen is an inert gas.
