# MnO2 + HCl = MnCl2 + Cl2 + H2O – Chemical Equation Balancer

Or you want a quick look: Instructions

MnO2 + 4HClMnCl2 + Cl2 + 2H2O

Manganese Dioxide + Hydrogen Chloride = Scacchite + Dichlorine + Water

## Instructions

To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

• Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
• Ionic charges are not yet supported and will be ignored.
• Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
• Compound states [like (s) (aq) or (g)] are not required.
• You can use parenthesis () or brackets [].

`Balance The Equation: MnO2 + HCl = MnCl2 + Cl2 + H2O 1. Label Each Compound With a Variable aMnO2 + bHCl = cMnCl2 + dCl2 + fH2O 2. Create a System of Equations, One Per Element Mn: 1a + 0b = 1c + 0d + 0f O: 2a + 0b = 0c + 0d + 1f H: 0a + 1b = 0c + 0d + 2f Cl: 0a + 1b = 2c + 2d + 0f 3. Solve For All Variables a = 1 b = 4 c = 1 d = 1 f = 2 4. Substitute and Verify Result MnO2 + 4HCl = MnCl2 + Cl2 + 2H2O L R Mn: 1 1 ✔️ O: 2 2 ✔️ H: 4 4 ✔️ Cl: 4 4 ✔️`
