Give the balanced equations for the following reactions .
Ethyne reacts with hydrobromic acid .

Explanation

To balance the equation for the reaction of ethyne with hydrobromic acid (HBr), we will follow these steps:

### Step 1: Write the chemical formulas
Ethyne is represented as C₂H₂, and hydrobromic acid is represented as HBr.

### Step 2: Identify the reaction
When ethyne reacts with HBr, it forms an intermediate product. The reaction can be represented as:
\[ \text{C}_2\text{H}_2 + \text{HBr} \rightarrow \text{C}_2\text{H}_3\text{Br} \]
