Q.

What is red tide?

Q. On heating ortho-boric acid to red hot, the residue is

Q. Sulphur dioxide is one of the components of polluted air. $S{O}_2$ is also a major contributor to acid rain. The correct and complete reaction to represent acid rain caused by $S{O}_2$ is

1. $2S{O}_2+O_2+2H_{2}O\to 2H_{2}S{O}_4$
2. $S{O}_2+O_3\to S{O}_3+O_2$
3. $S{O}_2+H_2{O}_2\to H_{2}S{O}_4$
4. $2S{O}_2+O_2\to 2S{O}_3$

3. $C{O}_2$
4. $O_3$

Q. what is acid rain and ozone?

Q. What is acid rain? Give some of its harmful effects.

1. 
2. 
3. 
4. 

Q.

Sulfur trioxide reacts with water during rain to form hydrochloric acid

1. True
2. False

Q. Convectional rainfall occurs in which type of area?

1. Mountain resin
2. Equatorial area
3. Hilly area
4. All of above

Q. Write in brief about 'acid rain'.

Q.

During a thunderstorm, rain water contains nitric acid. Why?

Q.

The natural reservoir of phosphorus is?

1. Rock

2. Animal bones

3. Seawater

4. Fossils

Q. Taj Mahal marble is affected by

Q. The pair of gases responsible for acid rain are:

1. $H_2,O_3$
2. $C{H}_4,O_3$
3. $N{O}_2,S{O}_2$
4. $CO,C{H}_4$

Q. The pH of the acid rain is approximately:

1. 5 to 6
2. 6 to 7
3. >10
4. 2 to 3

Q. Acid rain is the downpour of

1. carbon dioxide in rain
2. dust in rain
3. sulphur dioxide in rain
4. oxygen in rain

Q. Assertion :Major reservoirs of phosphorus are phosphate rocks and fossil bone deposits laid down in the past geological ages. Reason: During weathering of rocks, minute amounts of these phosphates dissolve in soil solution and are absorbed by the roots of the plants.

1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
3. Assertion is correct but Reason is incorrect
4. Both Assertion and Reason are incorrect

Q. Acid rain is caused by or recent reports of acid rain in some industrial cities are due to the effect of atmospheric pollution by:

1. excessive release of $C{O}_2$ by burning of fuels like wood and charcoal.
2. excessive release of $N{O}_2$ and $S{O}_2$ in atmosphere by burning of fossil fuels.
3. excessive release of $CO$ in atmosphere
4. excessive release of $N{H}_3$ by industrial plants and coal gas.

Q. Which among the following statements is correct?

1. ${CO}_2$ gas develops more acidity in rain-water than ${SO}_{@}$
2. $H_2{SO}_3$ is less acidic than $H_2{SO}_4$
3. $H{NO}_3$ is less acidic than $H{NO}_2$
4. ${SO}_2\left(g\right)$ is reduced in the atmosphere during thunderstorm

Q. Write about acid rain.

Q. How can an acid rain effect the aquatic life?

Q. Mycorrhizal fungi, which form a mutualistic association with many plant roots, are particularly sensitive to the effects of acid rain. These fungi facilitate the absorption of water and nutrients by the plants; in turn, the plants provide sugars and amino acids without which the fungi could not survive.

1. One partner benefits from the association and the other partner is harmed
2. One partner benefits from the association and the other partner is neither harmed nor helped
3. One partner preys upon the other partner
4. Both partners benefit from the association
5. Neither partner benefits from the association

Q. What is acid rain? Mention two of its effects.

Q. The pollutant in air responsible for acid rain is carbon monoxide.

1. True
2. False

Q. The pH of acid rain water is

1. 1.2
2. 5.6
3. 3.1
4. 6

Q. How does acid rain fall?

Q. Which one of the gases is responsible for causing acid rain in atmosphere?

1. $S{O}_2$
2. $C{O}_2$
3. $C{H}_4$
4. $O_3$
