Chapter 8, Problem 4E

Draw a box and then sketch five space-filling models of diatomic molecules within it, similar to those in Question 3. Draw an arrow and draw a product box to the right of your arrow. Add the remaining space-filling models necessary to depict the balanced reaction ${\text{X}}_2+{\text{Y}}_{\text{2}}\to {\text{XY}}_3$ (the reaction is not yet balanced), in which your five molecules represent the species ${\text{X}}_2$.
