Explanation:
Chemical equation:
Zn + HCl → ZnCl₂ + H₂
Balanced chemical equation:
Zn + 2HCl → ZnCl₂ + H₂
There are two atoms of hydrogen one atom of zinc and 2 atoms of chlorine on both side of equation.
The common oxidation state of zinc is +2 while tat of chlorine is -1 that's why two chlorine atoms combine with one atom of zinc to accept two electrons.
Zn⁺²Cl₂²⁻ negative and positive charges are equal in magnitude that's why over all compound is neutral.
While two atoms of hydrogen combine with each other through covalent bond by shearing the electrons.
The oxidation state of zinc is increased from 0 to +2 so it gets oxidized while that of chlorine is -1 to -2 is chlorine gets reduced.
