Synthesis Reactions: Identifying Combination Reactions with Examples
The correct answer is D) Zn + 2HCl → ZnCl2 + H2.
This reaction demonstrates a synthesis reaction because two or more substances combine to form a new substance. In this case, zinc (Zn) and hydrochloric acid (HCl) react to form zinc chloride (ZnCl2) and hydrogen gas (H2).
