Chemical reaction between Zinc metal and Hydrochloric acid is characterised by evolution of Hydrogen gas and change in temperature ( rise in temperature )
Zinc + Hydrochloric acid => Zinc Chloride + Hydrogen gas
=> Zn ( s ) + HCl ( aq ) => ZnCl2 ( aq ) + H2 ( g )
Above reaction is exothermic as heat is released during reaction and the temperature of the reaction mixture rise....
