Complete the following:
NaOH(aq) + ______ `to` NaCl(aq) + `H_(2)O(l)`

Explanation

To complete the reaction NaOH(aq) + ______ → NaCl(aq) + H₂O(l), we need to identify the missing reactant.

1. **Identify the components**: We have sodium hydroxide (NaOH), which is a strong base, and we need to find an acid that will react with it to form salt and water. The products given are sodium chloride (NaCl) and water (H₂O).

2. **Understand the reaction type**: This is a neutralization reaction where an acid reacts with a base to produce a salt and water. The general reaction can be represented as:
\[ \text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water} \]
