In acid rain_____oxides and ____dioxide will react with the tiny droplets of water in clouds. The rain from these clouds then falls as acid rain.

Options

A. sulphur, nitrogen
B. carbon, oxygen
C. sulphur, sulphate
D. ozone, oxalate

Answer

To solve the question regarding acid rain, we need to identify the oxides that react with water to form acids. Here’s a step-by-step solution:

### Step 1: Identify the oxides involved in acid rain
In acid rain, two specific oxides are known to react with water droplets in the atmosphere. These are sulfur oxides and nitrogen oxides.

**Hint:** Think about the common pollutants that can lead to acid formation in the atmosphere.

### Step 2: Specify the oxides
The two oxides are:
1. Sulfur dioxide (SO₂)
2. Nitrogen dioxide (NO₂)

**Hint:** Recall the chemical formulas of the oxides that are commonly associated with acid rain.

### Step 3: Reaction with water
When these oxides react with water, they form acids:
- Sulfur dioxide reacts with water to form sulfuric acid (H₂SO₄).
- Nitrogen dioxide reacts with water to form nitric acid (HNO₃).

**Hint:** Consider what happens when these gases dissolve in water.

### Step 4: Formation of acid rain
The resulting acids (sulfuric acid and nitric acid) mix with rainwater, leading to the phenomenon known as acid rain.

**Hint:** Remember that acid rain has a lower pH due to the presence of these acids.

### Final Answer
In acid rain, **sulfur oxides** and **nitrogen dioxide** will react with the tiny droplets of water in clouds.

### Summary
- Sulfur dioxide (SO₂) forms sulfuric acid (H₂SO₄).
- Nitrogen dioxide (NO₂) forms nitric acid (HNO₃).
- Together, these contribute to acid rain.
