Consider the following:
1. Oxide: Hydrogen 2. Oxides of Nitrogen 3. Oxides of Sulphur, which of the a causes/cause acid rain ?

Options

A. 1 and 2 only
B. 3 only
C. 2 and 3 only
D. 1, 2 and 3

Answer

To determine which oxides cause acid rain from the given options, we can follow these steps:

### Step 1: Understand the components involved in acid rain
Acid rain is primarily caused by the reaction of certain oxides with water in the atmosphere. The key oxides to consider are:
- Oxides of Nitrogen (NOx)
- Oxides of Sulphur (SOx)

### Step 2: Analyze the oxides listed
1. **Oxide of Hydrogen**: This is simply water (H2O) and does not contribute to acid rain.
2. **Oxides of Nitrogen**: When nitrogen oxides (NO and NO2) are released into the atmosphere, they can react with water to form nitric acid (HNO3), which contributes to acid rain.
3. **Oxides of Sulphur**: Sulphur oxides (SO2 and SO3) can react with water to form sulfuric acid (H2SO4), which also contributes to acid rain.

### Step 3: Identify which oxides cause acid rain
From the analysis:
- **Oxide of Hydrogen** does not cause acid rain.
- **Oxides of Nitrogen** do cause acid rain.
- **Oxides of Sulphur** do cause acid rain.

### Step 4: Conclusion
The oxides that cause acid rain from the options provided are:
- Oxides of Nitrogen
- Oxides of Sulphur

Thus, the correct answer is that both the second and third options (Oxides of Nitrogen and Oxides of Sulphur) cause acid rain.

### Final Answer
The oxides that cause acid rain are:
- Oxides of Nitrogen
- Oxides of Sulphur
