6. Write any 2 uses of natural gas.


7. Use of fossil fuels is harmful to our environment. Explain.

plz give me the correct answer​

Answer 1

Answer:

1. methane

Explanation:

2)greenhousee effect caused by the atmospheric accumulation of gases

3) Chemicals called odorants are added to natural gas .

4) compressed natural gas

5) we need to conserve our natural resources because it is the main source of our daily needs .and if these resources are harmed we will have short quantity of sources for food and living remember our future generation will need also our natural resources .

6) it is it is used in heating cooking and electricity generation it is also used as a fuel for vehicles .

7).burning fossil fuels MH a number of air pollutants that are harmful to both the environment and public health primary the result of burning coal contribute to acid rain and the formation of harmful particles matter .

maybe it's helpful for you ☺️☺️☺️

Answer 2

Answer:

1. Methane (94.60%), Ethane (1.05%), Propane (0.28%), Butane (0.17%) , Nitrogen (3.88%), Carbon dioxide (0.02%).

2.Global warming, Depletion of Ozone O3 Layer, Smog, Air Pollution, Acidification Of H2O Bodies.

3.Ethyl mercaptan is added to gas, which possesses that strong odour of rotten cabbages. The smell helps us detect where there is a leak, which actually makes a lot of sense from safety and security perspective.

4. Compressed Natural Gas

5. Because Their irrational consumption and over utilisation have led to socio-economic and environmental problems.

It takes million of years for the formation of natural resources. Natural resources are available in fixed quantity and they are non – renewable.

6. (i) Natural gas is used as a source of energy for heating, cooking, and electricity generation.

(ii) It is also used as a fuel for vehicles and as a chemical feedstock in the manufacture of plastics and other commercially important organic chemicals.

7. The main reason why fossil fuels cause so much damage is due to the amount of carbon dioxide or CO2 emitted when fossil fuels are burned. This burning and release of CO2 is a huge contributor to the greenhouse effect and climate change. More CO2 in our atmosphere causes less sunlight to escape back into space, causing the planet to warm. When fossil fuels are burned, CO2 isn't the only gas released. Other harmful gases such as nitrogen and sulfur oxides. Burning fossil fuels causes air pollution and smog.
