Question

when sulphur dioxide reacts with water and oxygen in air, it results in the production of -
1. snow
2. acid rain
3. nitrogen oxide
4. carbon dioxide​

Answer 1

Answer:

sulphuric acid

Explanation:

Sulphuric acid is produced when sulphur dioxide reacts with oxygen and water in the presence of a catalyst according to the reaction: 2SO2(g)+O2(g)+2H2O(l)⟶2H2SO4.

Answer 2

2. Acid rain is formed by the reaction of sulphur dioxide.

• Acid rain is the precipitation containing hazardous compounds.
• These compounds are acids when harmful gases like nitrogen oxide and sulphur dioxide reach the atmosphere.
• In the atmosphere, the gases react with available moisture and oxygen resulting in acid formation.
• The acids thus formed reaches the earth mixed with rain, causing dangerous consequences.
