  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A traditional car wax formula usually consists of a blend of carnauba wax, mixed with other waxes, such as beeswax, natural oils, and will sometimes also include petroleum distillates. Carnauba wax is a hard wax obtained from the leaves of a Brazilian palm tree which produces a glassy shine. Carnauba based waxes must be reapplied frequently in order to maintain shine. Beeswax is a durable wax found in honeycombs and used in car wax formulas to provide a protective barrier. Natural oils, such as linseed oil, are emollients use to provide added shine, luster, and protection, to the painted surface. Petroleum distillates are solvents derived from crude oil that make the wax easier to spread and to clean the paint.

So, the correct answer is option D.

Which of the following products obtained by destructive distillation of coal, is not properly matched?

  1. Coal tar - dyes, explosives, paints

  2. Coal gas - fuel

  3. Coke - drinking purposes

  4. Ammoniacal liquor - fertilizers
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Coke obtained by destructive distillation of coal is not used for drinking purposes. But it is largely used as a reducing agent in the extraction of metals from their ores.

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

  1. coal gas

  2. natural gas

  3. water gas

  4. petroleum
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

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.

  1. (i) and (ii)

  2. (ii) and (iii)

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

  4. All are correct
Reveal answer Fill a bubble to check yourself
C Correct answer
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.

c. needs very high pressure and high temperature.
d. causes air pollution.
Select the correct alternative.

  1. a, c and d

  2. b and d

  3. c and a

  4. d and c
Reveal answer Fill a bubble to check yourself
A Correct answer
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.
