Answer 2

True & False  :- Write T for 'true' or F for 'false' for the following statements-

1) Nitrogen is widely used in the fertilizer industry and as a coolant. True

2) Carbonic acid is formed by mixing of carbon dioxide and argon. True

3) A single atom of chlorine can destroy 1,00,000 molecules of ozone. False

This breaks up the molecule and releases chlorine and bromine atoms, which then destroy ozone in a subsequent chemical reaction. Although the amount of chlorine and bromine in the stratophere is quite low, alarmingly each free chlorine and bromine atom may be capable of destroying up to 100,000 ozone molecules.

4) Volcanic eruptions release pollutant gases like helium. True

5) Nitrogen makes 21% and oxygen makes 71% of air. False

The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen

6) Carbon dioxide is required for all green plants.​ True
