What is an example of a single-displacement reaction?
gpt
Zn + 2HCl → ZnCl2 + H2
Explanation: A single-displacement reaction is a type of chemical reaction where one element displaces another element from a compound, often resulting in the formation of a new compound. In this example, zinc (Zn) displaces hydrogen (H) from hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and hydrogen gas (H2).
