Solution Steps

Step 1: Understanding Single-Replacement Reactions

A single-replacement reaction, also known as a single-displacement reaction, occurs when an element reacts with a compound and takes the place of another element in that compound. The general form of a single-replacement reaction is: \[ A + BC \rightarrow AC + B \] where \( A \) is an element and \( BC \) is a compound. In this reaction, \( A \) replaces \( B \) in the compound, forming a new compound \( AC \) and releasing element \( B \).

Step 2: Analyzing Each Reaction

Let's analyze each given reaction to determine if it fits the pattern of a single-replacement reaction:

  1. \(\mathrm{HCl}(\mathrm{aq})+\mathrm{NaOH}(\mathrm{aq}) \rightarrow \mathrm{NaCl}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}\)
    This is a neutralization reaction between an acid and a base, not a single-replacement reaction.

  2. \(\mathrm{AgNO}_{3}(\mathrm{aq})+\mathrm{NaCl}(\mathrm{aq}) \rightarrow \mathrm{AgCl}(\mathrm{s})+\mathrm{NaNO}_{3}(\mathrm{aq})\)
    This is a double-replacement reaction, where the ions in the reactants exchange partners.

  3. \(2 \mathrm{HCl}(\mathrm{aq})+\mathrm{Zn}(\mathrm{s}) \rightarrow \mathrm{ZnCl}_{2}(\mathrm{aq})+\mathrm{H}_{2}(\mathrm{~g})\)
    Here, zinc (\(\mathrm{Zn}\)) replaces hydrogen (\(\mathrm{H}\)) in hydrochloric acid (\(\mathrm{HCl}\)), forming zinc chloride (\(\mathrm{ZnCl}_{2}\)) and releasing hydrogen gas (\(\mathrm{H}_{2}\)). This fits the pattern of a single-replacement reaction.

  4. \(\mathrm{Ba}(\mathrm{OH})_{2}(\mathrm{~s})+2 \mathrm{CuCNS}(\mathrm{s}) \rightarrow \mathrm{Ba}(\mathrm{CNS})_{2}(\mathrm{aq})+\mathrm{CuOH}(\mathrm{s})\)
    This is a double-replacement reaction, where the ions in the reactants exchange partners.

  5. \(\mathrm{HCH}_{3} \mathrm{COO}(\mathrm{aq})+\mathrm{NaHCO}_{3}(\mathrm{~s}) \rightarrow \mathrm{NaCH}_{3} \mathrm{COO}(\mathrm{aq})+\mathrm{CO}_{2}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{l})\)
    This is a reaction between an acid and a carbonate, resulting in the formation of carbon dioxide, water, and a salt. It is not a single-replacement reaction.

Final Answer

The reaction that is an example of a single-replacement reaction is: \[ \boxed{2 \mathrm{HCl}(\mathrm{aq})+\mathrm{Zn}(\mathrm{s}) \rightarrow \mathrm{ZnCl}_{2}(\mathrm{aq})+\mathrm{H}_{2}(\mathrm{~g})} \]
