Final answer:
In this reaction, solid zinc (Zn) reacts with aqueous hydrochloric acid (HCl) to produce aqueous zinc chloride (ZnCl₂) and hydrogen gas (H₂). The balanced equation for this reaction is: Zn (s) + 2 HCl (aq) → ZnCl₂ (aq) + H₂ (g). This reaction is an example of a hydrogen replacement reaction, where the hydrogen in the acid is replaced by an active metal.
Step-by-step explanation:
In this reaction, solid zinc (Zn) reacts with aqueous hydrochloric acid (HCl) to produce aqueous zinc chloride (ZnCl₂) and hydrogen gas (H₂). The balanced equation for this reaction is:
Zn (s) + 2 HCl (aq) → ZnCl₂ (aq) + H₂ (g)
This reaction is an example of a hydrogen replacement reaction, where the hydrogen in the acid is replaced by an active metal. It is important to balance the equation so that the number of atoms of each element is equal on both sides.
