Equalize the equation for the following redox reaction using electronic balance: HCl + MnO₂ → MnCl₂ + Cl₂ + H₂O

The interaction of concentrated chloride acid with manganese dioxide is a laboratory method for the production of chlorine gas in small quantities. The reaction products of the interaction are manganese chloride (MnCl2), chlorine (Cl2) and water (H2O).
Let’s write the interaction equation:
MnO2 + HCl = MnCl2 + Cl2 + H2O
We level using the electronic balance method:
Mn (+4) + 2e = Mn (+2) / 2/1
2Cl (-1) – 2e = Cl2 (0) / 2/1
We get the following equation with coefficients:
MnO2 + 4HCl = MnCl2 + Cl2 + 2H2O
