Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
In this reaction, solid zinc (Zn) reacts with hydrochloric acid (HCl) in an aqueous solution to produce zinc chloride (ZnCl2) in the form of an aqueous solution and hydrogen gas (H2). The reaction involves a transfer of electrons from zinc to hydrogen ions, resulting in the formation of zinc ions and hydrogen gas. The equation is balanced to ensure that the number of atoms of each element remains the same on both sides.
