Use the image to answer the question.
An illustration shows two cubes. The cube on the top is labeled Nitrogen (N2). Inside this cube, there are several sets of two identical balls attached to each other. The cube on the bottom is labeled carbon dioxide (CO2). Inside this cube, there are several sets of three balls attached to each other. There is one grey ball and two red balls in each set. The grey ball is in the middle.

The box on the top (labeled Nitrogen) consists of a pure substance (N2) while the box on the bottom (labeled carbon dioxide) consists of a pure substance (CO2).
The correct answer is: The box on the top consists of a pure substance (Nitrogen, N2) while the box on the bottom consists of a mixture (Carbon Dioxide, CO2).
To answer this question, let's analyze the information provided in the image. The cube on the top is labeled Nitrogen (N2) and it contains several sets of two identical balls attached to each other. This means that the cube on the top consists of nitrogen molecules (N2).
On the other hand, the cube on the bottom is labeled carbon dioxide (CO2) and it contains several sets of three balls attached to each other. Each set consists of one gray ball in the middle and two red balls. This arrangement represents the structure of a carbon dioxide molecule (CO2).
Based on this information, we can conclude that the cube on the top consists of a pure substance (nitrogen gas, N2) while the cube on the bottom consists of a pure substance (carbon dioxide gas, CO2). Therefore, the correct statement is: "The box on the top consists of a pure substance while the box on the bottom consists of a pure substance."
