Non-Renewable Sources of Energy

Kazakhstan produces $41\%$ of the world's total industry-grade uranium but has only one operational nuclear reactor for power generation. Give TWO limiting factors that could be likely reasons for the above fact.

Biomass is the organic material of plants and animals. It can be treated and used as fuels called biofuels. State one major advantage in the use of biofuels over fossil fuels

${}^2\mathrm{H} {+}^2\mathrm{H} \to \mathrm{X}+\mathrm{n}$

What is the formula for X in the given reaction?

Mention any two disadvantages of fossil fuels.

List the uses of compressed natural gas.

The non-renewable source of energy amongst the following is

The energy released when $3 \mathrm{g}$ of material is completely converted into energy during a nuclear reaction is (given, speed of light = $3\times {10}^8 \mathrm{m}/\mathrm{s}$):

 Read the following statements about the use of coal and petroleum as energy sources.

(i) These are energy sources formed from biomass.

(ii) Inexhaustible energy sources when used continuously.

(iii) On combustion release oxides of sulphur and nitrogen.

(iv) Clean and eco-friendly sources of energy.

Correct statements are:

For a nuclear reactor $48 \mathrm{KJ}$ of energy is produced per minute. If the energy released per fission is $3.2\times {10}^{-11} \mathrm{J}$ then the number of fissions which would be taking place in a reactor per second is

The amount of material that releases $4.5\times {10}^{14} \mathrm{J}$ of energy when it is completely converted into energy during a nuclear reaction. [Given speed of light = $3\times {10}^8 \mathrm{m}/\mathrm{s}$]
