Question

Balance the following reaction: Zn+HCl→ZnCl₂+H₂ .

a) Zn + 2HCl → ZnCl₂ + H₂
b) Zn + HCl → ZnCl₂ + 2H₂
c) 2Zn + HCl → ZnCl₂ + H₂
d) Zn + 3HCl → ZnCl_2 + H_2

Answer 1

The balanced equation for the reaction between zinc and hydrochloric acid is Zn + 2HCl → ZnCl₂ + 2H₂.

Step-by-step explanation:

The balanced equation for the reaction between zinc (Zn) and hydrochloric acid (HCl) is:

Zn + 2HCl → ZnCl₂ + 2H₂

In this reaction, one zinc atom combines with two hydrochloric acid molecules to produce one zinc chloride molecule and two hydrogen gas molecules.
