A reaction between an acid and a metal oxide to form a salt and water as the only products.
gold not reacts with water but reacts with Aqua regia HCl(3) : HNO3 (1)
Remember the general acid reaction eq'ns. Acid + Alkali = Salt + Water Acid + Base = Salt + Water Acid + Metal = Salt +Hydrogen Acid + Carbonate = Salt +Water + Carbon Dioxide. So if you react hydrochloric ACID with a METAL it will produce the gas HYDROGEN.
Insoluble metal oxide + strong acid ---> salt + water
Metals will react rapidly with most acids. If the acid is concentrated the reaction can be violent. To react one with the other simply drop acid onto the metal surface with an eye dropper or place the metal object into the acid (with care if the acid is strong).
A metal that does not react to acid, oxygen or water does not exist.
For example, platinum metals: Pt, Ir, Pd, Os, Rh, Ru.

Carbon dioxide is evolved along with the formation of water and metal salts.

Mercury is a metal that is liquid at room temperature and is nonreactive. Nonreactive means the metal does not react to acid or water.
Hydrogen gas is given off when metal reacts with acid. e.g. Zn + 2HCl ------> ZnCl2 + H2

A salt compound from the non-metal from the acid, and the metal from base.
Copper, silver, gold and platinum
