Two models of the same compound are shown. A top line labeled Model A saying C subscript 2 H subscript 4 O subscript 2. A bottom image with 2 C's connected by 1 black line. The left C has 3 H's connected to it by 1 black line each and the right C has 2 Os attached to it, the top O by two black lines and the bottom O by 1 black line. The bottom O also has an H attached to it by 1 black line.
