On strong heating boric acid yields

Options

A. B
B. `B_(2) H_(6)`
C. `B_(2) O_(3)`
D. `BO_(2)`

Answer

To solve the question "On strong heating boric acid yields," we will analyze the decomposition process of boric acid (H3BO3) step by step.

### Step-by-Step Solution:

1. **Identify the Compound**:
- The compound in question is boric acid, which has the chemical formula H3BO3.

2. **Heating Boric Acid**:
- When boric acid is subjected to strong heating, it undergoes a decomposition reaction.

3. **First Decomposition Step**:
- Upon strong heating, boric acid (H3BO3) first decomposes to form metaboric acid (HBO2) and water (H2O).
- The reaction can be represented as:
\[ H3BO3 \rightarrow HBO2 + H2O \]

4. **Further Heating of Metaboric Acid**:
- If the metaboric acid (HBO2) is heated further, it decomposes into boric oxide (B2O3) and more water (H2O).
- This can be represented as:
\[ 2 HBO2 \rightarrow B2O3 + H2O \]

5. **Final Product**:
- After the complete process of strong heating, the final product obtained is boric oxide (B2O3).

6. **Conclusion**:
- Therefore, the answer to the question "On strong heating boric acid yields" is boric oxide (B2O3).

### Final Answer:
The correct option is **C, B2O3 (Boric Oxide)**.
