Here's the balanced chemical equation for the reaction:
CuO (s) + 2HCl (aq) → CuCl₂ (aq) + H₂O (l)
Explanation:
* Copper oxide (CuO) is a basic oxide.
* Hydrochloric acid (HCl) is a strong acid.
* When a base reacts with an acid, a salt and water are produced.
* The copper(II) ion (Cu²⁺) from copper oxide combines with the chloride ion (Cl⁻) from hydrochloric acid to form copper(II) chloride.
* Water (H₂O) is also formed as a byproduct.
