Chapter 3, Problem 3.75PAE

3.75 The following pictures show a molecular-scale view of a

chemical reaction between the compounds AB₂ and B₂. (A

atoms are shown in blue and B atoms in white). The box

on the left represents the reactants at the instant of mixing,

and the box on the right shows what is left once the reac-

tion has gone to completion. Write a balanced chemical

equation for this reaction. As usual, your equation should

use the smallest possible whole number coefficients for all

substances.
