2. They are gases composed of

Oxygen and argon

Nitrogen and carbon dioxide

Nitrogen and oxygen

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.

3. What colour is sulfur dioxide?

Brown

Red

Reddish brown

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.

4. Name some harmful effects these gases cause

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. Name two such gases that causes air pollution

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.
