WebStep 2. Equalize the changes in oxidation number. Each Zn atom has lost two electrons, and each H atom has gained one electron. You need 2 atoms of H for every 1 atom of Zn. This gives us total changes of +2 and -2. Step 3. Insert coefficients to get these numbers. 1Zn + 2HCl → 1ZnCl2 +1H2. The balanced equation is.
