**Chemical Compounds and Their Associated Names**

The table below provides information about the formulas of various chemical compounds along with their molecular and acid names. This is a useful reference for students looking to understand the nomenclature of different compounds.

| Formula | Molecular Name | Acid Name |
|---------|-----------------|-----------|
| HCN     |                 |           |
| HF      |                 |           |
| H₂S    |                 |           |

- **Formula**: The chemical formula representing the compound.
- **Molecular Name**: The name of the molecule in its neutral, non-ionized form.
- **Acid Name**: The name of the compound when it acts as an acid in aqueous solution.

### Explanation:
- **HCN (Hydrogen Cyanide)** - Typically studied under organic and inorganic chemistry, its molecular form is known as hydrogen cyanide, which, when dissolved in water, forms hydrocyanic acid.
- **HF (Hydrogen Fluoride)** - Known in molecular form as hydrogen fluoride, it becomes hydrofluoric acid in aqueous solution.
- **H₂S (Hydrogen Sulfide)** - In molecular form, it is hydrogen sulfide, and in water, it forms hydrosulfuric acid.

For educational purposes, it is important to be able to identify the molecular and acid names for various compounds as this understanding forms the foundation for more advanced topics in chemistry.
