  1. black gold

  2. yellow gold

  3. green gold

  4. blue gold

Show answer
Correct Option: A
Explanation:

Petroleum is also called as the black gold because it is the important source of energy. Byproducts of petroleum are very valuable and expensive.

Thus, option $A$ is correct.

Anaerobic fermentation is a process which helps in the formation of:

chemistry rocks and minerals coal petroleum non-renewable sources of energy

  1. coal gas

  2. natural gas

  3. water gas

  4. petroleum

Show answer
Correct Option: B
Explanation:

Natural gas is formed by the action of anaerobic bacteria on the plants or vegetation thousand of years ago.Over the years under high temperature and pressure, methane gets converted to natural gas.

Petroleum is soluble in water.

  1. True

  2. False

Show answer
Correct Option: B
Explanation:
It is lighter than water and insoluble in water. So answer is B.

Petroleum is a renewable fossil fuel

chemistry rocks and minerals coal petroleum non-renewable sources of energy

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Petroleum is a fossil fuel which is formed deep under the earth's crust in thousands of years which is a non renewable resource which once depleted cannot be replenished back.It cannot be made artificially in the laboratories.

Natural gas mainly consist of:

chemistry rocks and minerals coal petroleum non-renewable sources of energy

  1. $C _2H _6$

  2. $CH _4$

  3. $C _3H _3$

  4. $C _4H _{10}$

Show answer
Correct Option: B
Explanation:
Natural gas is naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly includes varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide or helium.
So answer is B.

Select the incorrect statements among the following.
(i) Bitumen is used for metalling the roads.
(ii) Some inexhaustible natural resources like coal, petroleum and natural gas formed from the dead remains of living organisms are known as fossil fuels.
(iii) Many useful substances are obtained from coal (commercial importance), so it is also called as 'Black gold'.
(iv) Natural gas is used as starting material for the manufacture of a number of chemicals and fertilizers.

chemistry rocks and minerals coal petroleum non-renewable sources of energy

  1. (i) and (ii)

  2. (ii) and (iii)

  3. (ii),(iii) and (iv)

  4. All are correct

Show answer
Correct Option: C
Explanation:

1) Bitumen is the one of the component of petroleum which is used for metalling / surfacing the roads.

2) Coal, petroleum and natural gases are exhaustible natural resources. Hence, this option is wrong.
3) Petroleum is called as 'Black gold' because it gives many useful substances.Hence,this is wrong.
4) Coal is used as starting material for the manufacture of a number of chemicals and fertilizers. Hence option 4 is incorrect.

Coal is a fossil fuel and it cannot be prepared in a laboratory or industry because the formation of coal :
a. is very slow process.
b. needs very low pressure and low temperature.
c. needs very high pressure and high temperature.
d. causes air pollution.
Select the correct alternative.

chemistry rocks and minerals coal petroleum non-renewable sources of energy

  1. a,  c and d

  2. b and d

  3. c and a

  4. d and c

Show answer
Correct Option: A
Explanation:

Coal is a fossil fuel derived from organic matter. We get coal deep inside the Earth's crust in coal mines. When dead plants got buried into the bottom of the soil. Due to high pressure and temperature plants gets converted into fossil fuels. If it is burn in large quantity it causes pollution.
