1.

They are gases composed of
- A.
  
  Oxygen and argon
- B.
  
  Nitrogen and carbon dioxide
- C.
  
  Nitrogen and oxygen
Correct Answer
C. Nitrogen and oxygen

Explanation
The correct answer is nitrogen and oxygen. Nitrogen and oxygen are two of the most abundant gases in the Earth's atmosphere. Nitrogen makes up about 78% of the atmosphere, while oxygen makes up about 21%. These two gases are essential for supporting life on Earth, as oxygen is necessary for respiration and nitrogen plays a crucial role in the nitrogen cycle, which is important for the growth of plants and other organisms.

2.

Name two such gases that causes air pollution

Correct Answer
Nitric Oxide
Nitrogen Dioxide

Explanation
Nitric oxide and nitrogen dioxide are two gases that contribute to air pollution. Nitric oxide is produced from burning fossil fuels, particularly in vehicles and power plants. It reacts with oxygen in the air to form nitrogen dioxide, which is a brownish gas and a major component of smog. Both gases are harmful to human health and can cause respiratory problems, contribute to the formation of acid rain, and contribute to the greenhouse effect and climate change.

3.

_____ temperatures in the engine causes nitrogen and oxygen to react.

Correct Answer
High

Explanation
High temperatures in the engine cause nitrogen and oxygen to react.

Rate this question:
4.

Name some harmful effects these gases cause

Correct Answer
mental confusion
anxiety
restlessness
fatigue
lethargy

Explanation
These gases can have harmful effects on the human body, leading to mental confusion, anxiety, restlessness, fatigue, and lethargy. Exposure to these gases can disrupt brain function, causing confusion and difficulties in thinking clearly. It can also lead to feelings of anxiety and restlessness, making individuals feel on edge and unable to relax. The gases can also cause fatigue and lethargy, resulting in a lack of energy and motivation. Overall, these harmful effects can significantly impact a person's mental well-being and overall quality of life.

5.

What colour is sulfur dioxide?
- A.
  
  Brown
- B.
  
  Red
- C.
  
  Reddish brown
Correct Answer
C. Reddish brown

Explanation
Sulfur dioxide is reddish brown in color. This is because when sulfur dioxide is exposed to air, it reacts with oxygen to form sulfur trioxide, which is a reddish brown gas. Therefore, sulfur dioxide itself appears reddish brown in color.
