Neither, it is water a neutral substance.
When zinc oxide reacts with hydrochloric acid, it forms zinc chloride and water. This is a typical acid-base reaction in which the hydroxide ions from the zinc oxide react with the hydrogen ions from the hydrochloric acid to form water.
Hydrogen oxide is neither an acid nor an alkali. It is water, which is a neutral substance.
When you mix metal oxide and acid, you typically get a salt and water. The metal in the metal oxide reacts with the acid to form a salt, while the oxygen in the metal oxide combines with hydrogen from the acid to form water.
Acid
acid.
Aluminum oxide is classified as a metal oxide. Specifically, it is known as an amphoteric oxide, meaning it can react both as an acid (when combined with a base) and as a base (when combined with an acid).

metal + acid -> salt + water metal + oxygen -> metal oxide metal oxide + acid -> salt + water metal + water -> metal hydroxide + hydrogen Metal + Steam -> Metal Oxide + Hydrogen Metal + Acid -> Metal salt + Hydrogen
When a metal oxide neutralizes an acid, it produces a salt and water. This reaction is a type of acid-base reaction where the metal oxide acts as a base and the acid acts as an acid. The salt formed usually contains the metal cation from the metal oxide and the anion from the acid.
The oxide of fermium is not known.
Oxygen oxide is not a real substance.
