How to boron obtained from borax ? Give chemical equations with reaction conditions. Write the structure of `B_(2)H_(6)` and its reaction with `HCl`.

Explanation

To obtain boron from borax, we follow a series of chemical reactions. Below is a step-by-step solution to the question, including the necessary chemical equations and structures.

### Step 1: Understanding Borax
Borax is chemically known as sodium tetraborate decahydrate, with the formula:
\[ \text{Na}_2\text{B}_4\text{O}_7 \cdot 10\text{H}_2\text{O} \]

### Step 2: Heating Borax
When borax is heated, it loses water and decomposes to form sodium metaborate and boron trioxide:
