Question

For the following reaction identify the products formed and balance the equation.

MnO₂ + HCl ⇢?

Answer 1

• The balanced chemical equation is an equation where the number of atoms of different elements on the reactant side is equal to the number of atoms of the elements present on the product side of the reaction.
• It provides quantitative information about that reaction.
• It also indicates the molecular proportion of substances in the reaction.
• In the given equation MnO₂ + HCl$\to$
• Manganese dioxide(MnO₂) reacts with hydrochloric acid (HCl) to produce manganese(II) chloride (MnCl₂)along with the evolution of chlorine gas(Cl₂) and water(H₂O).
• The balanced equation is

MnO₂ (s)+ 4HCl(aq) ⇢ MnCl₂ (s)+ 2H₂O (aq) + Cl₂(g)

Hence the products are manganese(II) chloride (MnCl₂)along with the evolution of greenish yellow chlorine gas(Cl₂) and water(H₂O).
