Name the structure of the product formed when formaldehyde reacts with semicarbazide `(NH_(2)CONHNH_(2))`.

Explanation

To determine the structure of the product formed when formaldehyde reacts with semicarbazide, we can follow these steps:

### Step 1: Identify the Reactants
- **Formaldehyde (HCHO)**: This is the simplest aldehyde with the structure:
\[ \text{H}_2C=O \]
- **Semicarbazide (NH₂CONHNH₂)**: This compound has the structure:
