Any reaction between a chloride and HCl.
2HCl + Zn(OH)2 ---->ZnCl2 + 2H2O
The reaction is:Zn + HCl = ZnCl2 + H2The volume of hydrogen ia 1,7 L.
Sodium will react violently with dilute hydrochloric acid.
When dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.
When zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2.

It forms copper chloride and water.
The net ionic equation is Zn + 2H+ --> Zn2+ + H2
When zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2.
Hydrogen is produced, as illustrated with the metal zinc: Zn + 2 HCl -> ZnCl2 + H2.
Many metals including alkali metals, alkali earth metals, chromium, nickel and zinc react with dilute hydrochloric acid.
When HCl and Zn react they form two entirely new substances (H2 and ZnCl2). The change cannot be reverse by physical means.
when the penny is reacted with HCl, there must be somesort of area where the copper on the outside of the penny is removed so that the HCl can react with the zinc inside because HCl does not react with copper. Once the HCl reacts with the Zn inside, it will dissapear and therefore become less dense then the ZnCl2 that is formed which causes the penny to float
Zn + 2HCl --> ZnCl2 + H2
