The salt produced from zinc oxide (ZnO) plus hydrochloric acid (HCl) is zinc chloride (ZnCl₂).

Here's the balanced chemical equation for the reaction:

ZnO + 2HCl → ZnCl₂ + H₂O

This is a classic acid-base reaction where:

* Zinc oxide (ZnO) acts as a base.

* Hydrochloric acid (HCl) acts as an acid.

* Zinc chloride (ZnCl₂) is the salt formed.

* Water (H₂O) is the other product.
