Chapter 1, Problem 122E

Use triangles to represent atoms of element A and circles to represent atoms of element B. Draw an atomic level view of a homogeneous mixture of elements A and B. Draw an atomic view of the compound AB in a liquid state (molecules close together). Draw an atomic view of the compound AB after it has undergone a physical change (such as evaporation). Draw an atomic view of the compound after it has undergone a chemical change (such as decomposition of AB into A and B).
