2. How is coal formed ?

3. How is destructive distillation of Coal carried out ? What are the products formed and what are their main uses ?
​

Answer 1

Answer:

1.If a resource is renewable, it can still get exhausted. ... Answer: If we use renewable resources faster than they are renewed or if we disturb the natural method of their renewal, then most renewable resources get exhausted. For example: Groundwater is used faster than it is renewed

2.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

3. Destructive distillation of coal is carried out by heating coal strongly to 1000 °C in the absence of air. It yields various useful organic and inorganic products. ... Coal tar: used to make pesticides, explosives, perfumes, etc. Ammonium compounds: making nitrogenous fertilizers.

Answer 2

Explanation:

1. Question: If a resource is renewable, it can still get exhausted. Discuss with two examples.
3. Answer: If we use renewable resources faster than they are renewed or if we disturb the natural method of their renewal, then most renewable resources get exhausted. For example:
5. Groundwater is used faster than it is renewed.
7. Forest is a renewable resource provided we don’t disturb their natural growth.
