The reaction that will occur with water and a metal depends on the valence electron configuration of the metal. Group 1 alkali metals react with water vigorously and sometimes explosively. This reaction produces a metal hydroxide and hydrogen gas. For group to alkaline earth metals, beryllium does not react. Magnesium burns in steam to produce magnesium oxide and hydrogen gas. It also reacts in cold water to form magnesium hydroxide and hydrogen gas. Further down group 2 the metals react increasingly with water to form the metal hydroxide and hydrogen gas. For the most part transition metals do not react with water. Mn (IV) will form MnO2 with water. Vanadium 4+ or 5+ forms VO2+ with water. Cr(VI) reacts with water to from the chromate and dichromate ions.
Metallic hydroxides are formed when a metal reacts with water or a base to produce a metal cation and hydroxide anion (OH-). For example, when sodium metal reacts with water, it forms sodium hydroxide and hydrogen gas. The metal hydroxide then dissociates in solution to release hydroxide ions.
When a metal oxide reacts with an acid, a salt and water are formed as products. Additionally, carbon dioxide gas may be produced if the metal oxide is a carbonate.
When a metal carbonate reacts with an acid, the products formed are a salt, carbon dioxide gas, and water. The metal from the carbonate combines with the acid to form a salt, carbon dioxide gas is released as a byproduct, and water is also produced in the reaction.
When a metal oxide reacts with a dilute acid, it forms a salt and water. The metal in the oxide replaces the hydrogen ion in the acid to form the salt.
The product formed when benzoic acid reacts with ethanol is ethyl benzoate, along with water. This reaction is an esterification process, where the -OH group of the benzoic acid reacts with the -OH group of ethanol to form the ester and water as a byproduct.
A cation is formed.

When a metal oxide reacts with water, it forms a metal hydroxide. This reaction typically involves the metal oxide releasing hydroxide ions when it reacts with water molecules. Metal hydroxides are basic compounds that can dissociate in water to form metal cations and hydroxide anions.
A metal oxide reacts with water to produce a metal hydroxide.
When a metal oxide reacts with an acid, it produces a salt and water. The metal oxide will neutralize the acid by forming water, and the metal ion in the oxide will combine with the non-metal ion from the acid to form the salt. For example: iron(III) oxide reacting with hydrochloric acid produces iron(III) chloride and water.
