Answer to Problem 73AP

Cl2+2KBrBr2+2KCl is the balanced equation.

Explanation of Solution

The given equation is,

Cl2+KBrBr2+KCl

The equation is not balanced as there are two chlorine atoms in the reactant side and product has only one. The reactant side has one bromine and the product side has two bromine. This unbalanced equation is balanced by multiplying two to the potassium bromide on the reactant side and 2 on the product side of potassium chloride.

The balanced equation is given as,

Cl2+2KBrBr2+2KCl.
