Carborundum is obtained when silica is heated at high temperature with

Options

A. carbon
B. carbon monoxide
C. carbon dioxide
D. calcium carbonate

Answer

To solve the question about how carborundum is obtained, we can follow these steps:

### Step 1: Identify the components involved
We need to know what carborundum is and what materials are involved in its production. Carborundum is also known as silicon carbide (SiC).

### Step 2: Understand the reaction
Carborundum is produced by heating silica (SiO2) with carbon (C) at high temperatures. This is a well-known chemical reaction.

### Step 3: Write the balanced chemical equation
The reaction can be represented as:
\[ \text{SiO}_2 + 3\text{C} \rightarrow \text{SiC} + 2\text{CO} \]

### Step 4: Analyze the reaction
In this reaction:
- Silica (SiO2) reacts with carbon (C).
- The products of the reaction are silicon carbide (SiC) and carbon monoxide (CO).

### Step 5: Conclusion
From the above analysis, we conclude that carborundum (SiC) is obtained when silica is heated at high temperature with carbon.

### Final Answer
The correct answer is: **Carbon**.
