Question 4

What products form when zinc reacts with dilute hydrochloric acid?

A Zn(OH)₂ and H₂ B ZnCl₂ and H₂ C ZnCl₂ and Cl₂ D ZnCl and H₂

The right answer is the one marked above.

ZnCl₂ and H₂. Zn + 2HCl → ZnCl₂ + H₂.

Zinc is divalent, so the formula is ZnCl₂, not ZnCl. The hydroxide forms with water, not with an acid.
