SO(2) as pollutant can be controlled by ...

`SO_(2)` as pollutant can be controlled by
(I) using solar energy , nuclear energy, hydroelectric energy.
(II) low sulphur fuels , natural gas.
(III) desulphonation of high-sulphur coal and oil before burning by `FGD`.
(IV) using water under high pressure.

A

Both I and II

B

Both I and III

C

I,II and IV

D

I,II and III

Text Solution

Verified by Experts

The correct Answer is:
D
`SO_(2)` in the atmosphere is due to burning of sulphur containing fossil fuel, `S+O_(2) rarr SO_(2)` and
from smelting and roasting of sulphides.
`CuFeS_(2)+O_(2) rarr Cu_(2)O+FeO+SO_(2)`
`SO_(2)` content can be controlled by using alternate source of energy for burning, as nuclear energy , solar energy , hydroelectric energy.
Fuels containing sulphur are desulphonated before burning by `FGD` (fuel Gas Desulphuristion).
If `H_(2)O` under high pressure is used , it will dissolve `SO_(2)` and will lower `pH` of the soil and thus fertillity is decreased.

Renewable energy is energy produced from sourece that do not deplete or can be replenished within a human's life time. The most common examples include wind, solar, geothermal, biomass, and hydroelectric power. This is in contrast to non-renewable sources such as fossil fuels. Most renewable energy is derived direcetly or indirectly from the sun. Sunlight can be captured directly using solar technologies. The sun's heat drives winds, whose energy is captured with turbines. Plants also rely on the sun to grow and their stored energy can be utilized for boienergy. Not all renewable energy sources rely on the sun. For example, geothermal energy utilizes the Earth's internal heat, tidal energy relies on the gravitational pull of the moon, and hydroelctric power relies on the flow of water. Why will energy from fossil fuel be over soon?

The energy which we obtain from the sun is called solar energy or radiant energy. The sun's energy is stored in coal, natural gas, water and wind. Coal, oil, and natural gas are known as fossil fuels. Fossil fuels were formed over millions of years ago when the remains and fossils of prehistoric plants and animals sank to the bottom of swamps and oceans. These animal and plant remain were slowly covered and crushed by layers of rock, mud, sand, and water. The pressure of all those layers caused the plants and animals to break down and change into coal, oil and natural gas. We use the energy in these fossil fuels to make electricity. As of the year 2019, most of the energy we use comes from fossil fuels. However, fossil fuels are known as non-renewable sources of energy. They cannot be used over and over again. This means that one day they will run out! The energy source that uses collectors to heat water or air in buildings is
