Which product is seen when industrial chemicals combine with condensing water vapour ?

Options

A. Ozone depletion
B. Acid rain
C. Global warming
D. Greenhouse effect

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the product formed when industrial chemicals combine with condensing water vapor.

2. **Identifying Industrial Chemicals**: Industrial chemicals often include various gases released during manufacturing processes. Two common types of these gases are nitrogen oxides (NOx) and sulfur oxides (SOx).

3. **Combining with Water Vapor**: When these gases (NOx and SOx) come into contact with condensing water vapor in the atmosphere, they can undergo chemical reactions.

4. **Formation of Acids**: The combination of nitrogen oxides with water vapor can lead to the formation of nitric acid (HNO3), while sulfur oxides can react with water vapor to form sulfuric acid (H2SO4).

5. **Resulting Products**: Therefore, the products seen when industrial chemicals, specifically nitrogen oxides and sulfur oxides, combine with condensing water vapor are nitric acid and sulfuric acid.

6. **Conclusion**: The primary products formed are oxides of nitrogen and sulfur, which can contribute to acid rain and other environmental issues.

**Final Answer**: The products seen when industrial chemicals combine with condensing water vapor are oxides of nitrogen and sulfur.
