Zn does not reacts with water ... Elementary zinc does not react with water molecules. The ion does form a protective, water insoluble zinc hydroxide (Zn(OH)2) layer with dissolved hydroxide ions, according to the following reaction mechanism:it only reacts with boiling water forming zinc hydroxide and hydrogen...

Zinc metal does not react violently with water. It hardly oxidises under normal conditions. A coating of zinc (called galvanising) is used to protect steel from rusting.Zinc has a coating of the oxide that protects it from reaction with oxygen.It becomes vulnerable to oxidation in the presence of other substances that weaken its oxide layer. Acids will quickly dissolve zinc, as will alkalies. Acids produce zinc 2+ cations, whereas alkalies produce zincate ZnO2(2-) anions.inc has a coating of the oxide that protects it from reaction with oxygen.
