Tin is extracted from tin stone by heating it in a furance with

Options

A. `CaCO_(3)`
B. Coal
C. CaO
D. Steam

Explanation

### Step-by-Step Solution:

1. **Identify the Ore**:
- The ore from which tin is extracted is called tin stone, which is chemically represented as SnO₂ (tin(IV) oxide).

2. **Understand the Extraction Process**:
- The extraction of tin from its ore involves a reduction process. In this case, SnO₂ is reduced to tin (Sn) using a reducing agent.

3. **Select the Reducing Agent**:
- The reducing agent used in this process is carbon, which is typically in the form of coal or coke.

4. **Write the Chemical Reaction**:
- The reduction reaction can be represented as:
\[ \text{SnO}_2 + \text{C} \rightarrow \text{Sn} + \text{CO}_2 \]
- Here, carbon (C) reacts with tin(IV) oxide (SnO₂) to produce tin (Sn) and carbon dioxide (CO₂).

5. **Temperature of the Process**:
- The extraction process is carried out at high temperatures, approximately 2500 degrees Fahrenheit (which is around 1371 degrees Celsius).

6. **Conclusion**:
- Therefore, tin is extracted from tin stone by heating it in a furnace with coal.

### Final Answer:
Tin is extracted from tin stone (SnO₂) by heating it in a furnace with coal.
