In the balanced chemical reaction of MnO₂, the coefficient of H⁺ is 4.
Balanced chemical reaction
The chemical equations which have the same number and same type of each atom on both sides of the equation is known as balanced chemical equation. The coefficients in a balanced equation must be always the simplest whole number ratio. Mass is always conserved in chemical reactions i.e., neither destroyed nor created.
Balanced chemical reaction of MnO₂ is given as:
5MnO₂ + 4H⁺ → 3Mn₂ + 4H₂O + 2MnO₄⁻
Hence, the coefficient of H⁺ in the balanced chemical equation of reduction MnO₂ is 4.
