Write one balanced reaction representing - nuclear fusion.

Explanation

To write a balanced reaction representing nuclear fusion, we can consider the fusion of hydrogen isotopes to form helium. Here’s a step-by-step solution:

### Step 1: Identify the reactants
In nuclear fusion, light nuclei combine to form a heavier nucleus. A common example is the fusion of deuterium (²H) and tritium (³H) to form helium (⁴He).

### Step 2: Write the unbalanced reaction
The unbalanced reaction for the fusion of deuterium and tritium is:
\[
