The products when Zinc metal reacts with Hcl( Hydrogen chloride ) is hydrogen gas and zinc chloride ZnCl₂ with the evolution of heat.
The reaction of Zn metal and hydrochloric acid is as follows
Zn + HCl → ZnCl2 + H2.
This is called a single replacement reaction where the metal, zinc reacts readily with hydrochloric acid,to displace the hydrogen to form zinc chloride, which is a salt and bubbles of hydrogen gas.
The reaction has a negative enthalpy due to the heat produced.
