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 Concept of Particulates
Particulates refer to tiny particles or droplets that are suspended in the air. They can be solid or liquid and include various substances such as dust, salt, and acids like sulfuric acid.

**Hint:** Remember that particulates can be both solid and liquid, and they are measured in terms of size.

### Step 2: Identify the Specific Substance
In this case, we are focusing on sulfuric acid (H₂SO₄) fog. This refers to the tiny droplets of sulfuric acid that can be found in the atmosphere, especially in polluted air.

**Hint:** Focus on the specific chemical compound mentioned in the question, which is sulfuric acid.

### Step 3: Research the Size Range
The size of particulates can vary widely. For sulfuric acid fog, it has been established that the size of the particulates typically falls within a specific range.

**Hint:** Look for reliable sources or studies that provide information on the size of sulfuric acid droplets in the atmosphere.

### Step 4: State the Size Range
Based on the information gathered, the size of particulates of sulfuric acid fog lies in the range of 500 to 1000 nanometers (nm).

**Hint:** Remember to specify the unit of measurement (nanometers) when stating the size range.

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