Question 1

Which gas is the main contributor to the formation of acid rain?

Accepted Answer

Sulfur dioxide (SO₂)

Answer

Carbon dioxide (CO₂)

Answer

Oxygen (O₂)

Answer

Nitrogen (N₂)

Question 2

Which gas listed below is a major cause of acid rain formation?

Accepted Answer

Sulfur dioxide (SO₂)

Answer

Ozone (O₃)

Answer

Methane (CH₄)

Answer

Carbon dioxide (CO₂)

Question 3

If a city reduces its sulfur dioxide (SO₂) emissions by 40% while all other emissions remain the same, what is the most likely effect on the average pH of rain that falls in that city?

Accepted Answer

The average pH of the rain will increase (become less acidic) because less sulfuric acid will be formed.

Answer

The average pH of the rain will stay the same because sulfur dioxide does not influence rain acidity.

Answer

The average pH of the rain will decrease (become more acidic) because the remaining SO₂ will react more efficiently with water vapor.

Answer

The average pH of the rain will become unpredictable because other pollutants will dominate the acidity.
