Question

Balance the following chemical equations.
i) NaOH + H₂SO4 → Na₂SO₄ + H₂O
ii) MnO₂ + HCl → MnCl₂ + H₂O + Cl₂

Open in App

Solution

Dear student
i) The given chemical equation

NaOH + H₂SO4 → Na₂SO₄ + H₂O
To balance two sodium atoms on product side we assign coefficient 2 to NaOH on reactant side and two balance four Hydrogen on reactant side we assign coefficient 2 to H₂O on product side.

Therefore the balanced form of the above chemical equation will be

2NaOH + H₂SO4 → Na₂SO₄ + 2H₂O

ii) The given chemical equation

MnO₂ + HCl → MnCl₂ + Cl₂ + H₂O
To balance four chlorine atoms on product side we assign a coefficient 4 to HCl and then to balance four Hydrogen on reactant side we assign a coefficient 2 to H₂O on product side

Therefore the balanced form of the above chemical equation will be

MnO₂ + 4HCl → MnCl₂ + Cl₂ + 2H₂O

Hope this answers your question.
Regards
