Chapter 22.4, Problem 21.4.2PE

Interpretation Introduction

Interpretation: The balanced equation for the reaction between ${\text{Br}}^{-}$ and ${\text{Cl}}_{\text{2}}$ is to be stated.

Concept introduction: According to the law of conservation of mass, the mass of the reactants that take part in a chemical reaction is equal to the mass of the products formed in the reaction.

The balancing of a chemical equation involves making the number of atoms on the reactant side and the product side equal.

The oxidizing power of elements decreases while moving down the group in a periodic table.

To determine: The balanced chemical equation for the reaction of ${\text{Br}}^{-}$ and ${\text{Cl}}_{\text{2}}$ .
