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...

Masters degree with Distinction from Imperial College London, first degree in Chemistry from University of Central Lancashire. Zinc + Hydrochloric acid is a basic metal acid reaction. When the Zinc is added to the acid, the zinc dissolves and reacts with the acid, forming hydrogen gas and the salt Zinc Chloride. These sorts of reactions (metal + acid) will always result in a salt (in this case, zinc chloride) and hydrogen gas. The observations from this experiment would be white-gray solid is added to colorless liquid. Solid dissolves and a colorless, odorless gas is formed.
