B,C Correct answer
Explanation

Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions. Acid rain pollutes water and soil. It can have harmful effects on plants, aquatic animals and infrastructure.

How individuals can help to prevent acid rains?

  1. By using public transportation

  2. Using the electrical energy efficiently

  3. Simply walking wherever possible

  4. All

D Correct answer
Explanation

All the above activities result in the less use of fossil fuels, and hence less release of acid rain causing oxides.


Hence the correct option is D.

The pollutants in the air are:              

  1. melting white marbles of Taj Mahal.

  2. discoloring white marbles of Taj Mahal.

  3. forming cracks in the marbles of Taj Mahal.

  4. all of above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Since the area in which Taj Mahal is located is surrounded by many industries and factories, they emit a great amount of pollutants into the atmosphere, They even release toxic and acidic components in the near by water bodies. The pollutants in air are discoloring the white marbles of Taj Mahal due to acidic corrosion (caused by the oxides of non-metals like sulfur and nitrogen).

Acid rain can be prevented by:

  1. use of cleaner fuels

  2. attaching devices known as scrubbers in the chimneys

  3. both A and B

  4. none of above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

One of the most fundamental acid rain solutions is to utilize fuels that burn more cleanly or to burn coal more efficiently. This will greatly reduce the possibilities of acid rain developing in the atmosphere.

 As far as industrial power plants are concerned, the best solution is to attach devices known as scrubbers in the chimneys of these plants. These scrubbers reduce the amount of sulfur produced in the smoke by 90-95%.

Industries like Mathura Oil Refinery produce pollutants like:

  1. sulphur dioxide

  2. nitrogen dioxide

  3. both a and b

  4. hydrochloric acid
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The industries located in and around Agra like rubber processing, automobile, chemicals and especially Mathura Oil Refinery have been responsible for producing pollutants like sulphur dioxide and nitrogen dioxide, which contaminate the environment by producing dissolved acids in the air.

The major threat to Taj Mahal is:

  1. acid rain.

  2. hydrogen peroxide.

  3. Both a and b.

  4. None of the above.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. 

Acid rain corrodes the marble (calcium carbonate) of Taj Mahal. It causes damage to this wonderful structure, causing yellowing of marble.

Carbon monoxide is naturally produced by oxidation of   X  , a gas present in swamp area while it can be produced by   Y     of fuels containing carbon.

  1. X - $CO _{2}$, Y = complete combustion
  2. X - $CH _{4}$, Y = incomplete combustion

  3. X = C, Y = oxidation
  4. X = $CH _{4}$, Y = complete combustion
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Carbon monoxide is basically formed when an object is burned. Methane, which is a natural gas produces  CO after oxidation. Methane, produces less CO as compared to other units of gas. Incomplete combusion results in creation of poisonous CO. It occurs when supply of oxygen is poor.

Green plants during day time absorb :

  1. $O _{2}$
  2. $CO _{2}$
  3. $CO$
  4. $N _{2}$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A plant, like an animal, needs energy. Plants have a process called photosynthesis to transform light energy into chemical energy (glucose sugar). Plants produce oxygen during photosynthesis, the oxygen is derived from the water it intakes and not from the carbon dioxide. 


The hydrogen from water, the carbon from carbon dioxide, and the oxygen from carbon dioxide go into the glucose compound  (C$ _6$H$ _{12}$O$ _6$)

Hence, the correct option is $\text{B}$
