Answer 2

(b) $SO_{2}$ is  the following can be called contaminant .

• $SO_{2}$can create tiny particles when it reacts with other substances in the environment. Particulate matter (PM) pollution is caused by these particles. Small particles can go deep into the lungs and cause health issues if there are enough of them.
• Sulfuric acid is formed when sulphur dioxide reacts with water and air, and it is the major component of acid rain. Acid rain has the potential to induce deforestation. Acidification of streams is harmful to aquatic life.
• Sulphur dioxide ($SO_{2}$) is a pollutant in the air that is detrimental to both plants and people. It is made up of sulphur and oxygen atoms. $SO_{2}$forms acid rain when it dissolves in rainwater. In the presence of moisture,$SO_{3}$is transformed to $H_{2} SO_{4}$, which is then released as acid rain.
