3. In the reaction of solid zinc with hydrochloric acid
(HCI), the products of hydrogen gas and aqueous
zinc chloride are produced.
Which of these is the balanced equation from the
reaction?
A. Zn(s) + HCl(aq) → ZnCl₂ (aq) + H(g)
B.
2Zn(s) + 4HCl(aq) → Zn₂Cl4 (aq) + H₂(g)
C. Zn(s) + 2HCl(aq) ZnCl₂(aq) + H₂(g)
D. Zn₂ (s) + HCl(aq) → 2ZnCl(aq) + H₂(g)
