A certain type of coal is found to have 75% carbon in it. Which type of coal could this most probaly be?

Options

A. Peat
B. Lignite
C. Anthracite
D. Bituminous coal

Answer

To determine which type of coal contains approximately 75% carbon, we can analyze the carbon content of different types of coal. Here’s a step-by-step solution:

### Step 1: Understand the Types of Coal
There are several types of coal, each with a different percentage of carbon content. The main types include:
- **Peat**: Contains less than 60% carbon.
- **Lignite**: Contains about 65-70% carbon.
- **Bituminous Coal**: Contains about 70-86% carbon.
- **Anthracite**: Contains about 86-92% carbon.

### Step 2: Analyze the Given Percentage
The question states that the coal in question has 75% carbon. We need to find which type of coal falls within this range.

### Step 3: Compare the Carbon Content
- **Peat**: Less than 60% carbon (not applicable).
- **Lignite**: 65-70% carbon (not applicable).
- **Bituminous Coal**: 70-86% carbon (this range includes 75%).
- **Anthracite**: 86-92% carbon (not applicable).

### Step 4: Conclusion
The only type of coal that has a carbon content that includes 75% is **Bituminous Coal**. Therefore, the answer to the question is that the coal with 75% carbon is most likely **Bituminous Coal**.

### Final Answer:
**Bituminous Coal**
