Question
**Understanding Chemical Reactions: Sulfuric Acid and Water Interaction**

Consider the following chemical reaction and the fact that H\(_2\)SO\(_4\) (sulfuric acid) is a strong acid:

\[ \text{H}_2\text{SO}_4 + \text{H}_2\text{O} \rightarrow \text{HSO}_4^- + \text{H}_3\text{O}^+ \]

If 0.0005 moles of H\(_2\)SO\(_4\) react with water, how many moles of H\(_2\)SO\(_4\) remain?

### Options:

- ∘ 0
- ∘ 0.0005
- ∘ 0.001
- ∘ 1

### Explanation:

In this reaction, H\(_2\)SO\(_4\) dissociates completely in water, as it is a strong acid. Therefore, the number of moles of H\(_2\)SO\(_4\) that react would be completely converted into HSO\(_4\)⁻ and H\(_3\)O\(^+\). Thus, 0.0005 moles of H\(_2\)SO\(_4\) will be entirely used up in the reaction, leaving 0 moles remaining.

Understanding this complete dissociation is crucial for solving similar problems in chemistry, highlighting the nature of strong acids in aqueous solutions.
