The size of particulates of `H_(2)SO_(4)` fog lies in the range.

Options

A. 5-100 nm
B. 100-500 nm
C. 500-1000 nm
D. 1000-10,000 nm

Answer

To determine the size range of particulates of sulfuric acid (H₂SO₄) fog, we can follow these steps:

### Step 1: Understand the Composition of H₂SO₄ Fog
Sulfuric acid fog consists of tiny droplets of sulfuric acid suspended in the air. These droplets are formed from the condensation of water vapor in the presence of sulfuric acid.

**Hint:** Consider the nature of fog and how it forms from vapor.

### Step 2: Identify the Size Range of Particulates
Research indicates that the size of particulates in H₂SO₄ fog typically falls within a specific range. For H₂SO₄ fog, the particulates are generally found to be between 500 to 1000 nanometers in diameter.

**Hint:** Look for reliable sources or scientific literature that discusses the size of aerosol particulates.

### Step 3: Analyze the Options Given
If the question provides multiple-choice options (A, B, C, D), we can compare the identified size range (500 to 1000 nm) with the options provided.

- Option A: Incorrect
- Option B: Incorrect
- Option C: Correct (if it states 500 to 1000 nm)
- Option D: Incorrect

**Hint:** Cross-check the options with the size range you have determined.

### Step 4: Conclude the Correct Answer
Based on the analysis, the correct option that represents the size range of particulates of H₂SO₄ fog is the one that states 500 to 1000 nanometers.

**Hint:** Ensure to confirm the correct option before finalizing your answer.

### Final Answer
The size of particulates of H₂SO₄ fog lies in the range of **500 to 1000 nanometers**.
