Weekly Quiz Competition

Question 1
1 / -0

Rocket fuel is:

A
Ammonium phosphate

B
Liqiud oxygen

C
Liqiud ammonia

D
Solid $$KCl$$

Solution

Liquid -fuel rockets most commonly use liquid oxygen and either kerosene or liquid hydrogen. These combinations work well in space and down closer to the ground.
Question 2
1 / -0

Naphthalene balls used to repel moths and other insects are obtained from X. These days Y, a petroleum product is used in place of X for metalling the roads. What are X and Y respectively?

A
Coke, coal

B
Coal, coke

C
Bitumen, coal tar

D
Coal tar, bitumen

Solution

Naphthalene balls used to repel moth and other insects are also obtained from coal tar. These days bitumen, a petroleum product is used in place of coal tar for metalling roads.

Hence, X is coal tar and Y is bitumen.
Question 3
1 / -0

All are the mixtures of various organic compounds except:

A
petrol/diesel

B
octane

C
vaseline

D
kerosene

Solution

All of the given substances are mixtures of various organic compounds except octane. Because octane is a pure saturated hydrocarbon containing $$8$$ carbon atoms.
Question 4
1 / -0

Paraffin wax is used for making:

A
vaselines

B
candles

C
ointments

D
all of the above

Solution

Paraffin wax is derived from petroleum, coal and consist of a mixture of hydrocarbon molecules between 20-40 carbon atoms.
Paraffin wax is used in the manufacturing of vaseline, ointments, candles, electrical insulation.
Question 5
1 / -0

Choose the incorrect statement among the following.

A
Many useful substances are obtained from petroleum and natural gas. These are termed as 'petrochemicals'

B
Hydrogen gas obtained from natural gas is used in the production of fertilizers

C
Due to the great commercial importance of petroleum, it is also called 'black gold'

D
Natural gas is stored under low pressure as compressed natural gas (CNG)

Solution

CNG is made by compressing natural gas (which is mainly composed of methane, CH₄ stored at high pressure), to less than 1 percent of the volume, it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of 20–25 MPa (2,900–3,600 psi), usually in cylindrical or spherical shapes.
Thus they are stored under high pressure.
Question 6
1 / -0

Which of the following is used for refining of petroleum?

A
Steam distillation

B
Distillation under reduced pressure

C
Solvent extraction

D
Fractional distillation

Solution

Fractional distillation is used for the refining of petroleum.
Petroleum is a mixture of various compounds having small differences in their boiling point. Fractional distillation is very useful in this case because it can separate all the components of the mixture (like petrol, diesel, kerosene, etc.)
Hence, option $$D$$ is correct.
Question 7
1 / -0

Which of the following represents the foul smelling, black, thick, viscous liquid obtained from destructive distillation of coal?

A
Coke

B
Coal tar

C
Coal gas

D
None of these

Solution

Coal tar is the foul smelling, black, thick, viscous liquid obtained from destructive distillation of coal.
Question 8
1 / -0

The compound obtained from coal is/are:

A
coke

B
coal tar

C
coal gas

D
all of the above

Solution

Coal is a fossil fuel. When coal is processed in industries, coke, coal tar, and coal gas are obtained. Hence the correct option is D.
Question 9
1 / -0

Coal is a fossil fuel and it cannot be prepared in a laboratory or industry. Because of the formation of coal:
a. is a 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 alternatives.

A
a, c and d

B
b and d

C
c and a

D
d and c

Solution

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 get converted into fossil fuels. If it burns in large quantity, it causes air pollution.
Question 10
1 / -0

The fraction of petroleum used as jet fuel is:

A
petrol

B
kerosene

C
diesel

D
alcohol

Solution

Jet fuel is a clear to straw colored fuel based on either an unleaded kerosene or a naphtha kerosene blend. It is similar to diesel fuel and can be used in either compression ignition engines or turbine engines.
