Solution: Classify each of the following molecular diagrams as a pure substance or a mixture.

Problem

Classify each of the following molecular diagrams as a pure substance or a mixture. Scene A is a collection of molecules each with a black sphere combined with two red spheres. Scene B is a collection of two different molecules. One one side of the sample there are molecules consisting of black spheres combined with gray spheres, and on the other side of the sample there are molecules consisting of a red sphere bonded to two gray spheres. Scene C is a collection of two different molecules. The molecules consist of a red sphere combined with two gray spheres and the second molecule is two black spheres surrounded by six gray spheres and one red sphere. The molecules appear to be randomly distributed throughout the sample. Scene D is a collection of isolated gray spheres.
