Matter+and+Measurement

The first picture shows that the matter does not have uniform properties. There are two different kinds of matter in the picture, small red circles and large gray circles. The mixture is hetero-geneous because there are different kinds of matter mixed in it. The second picture shows that the matter does not have a fixed composition, the circles are different and they are grouped in pairs separately. Therefore, it is a solution. The last picture shows that the first graphic is not chemically decomposable because, it is an element, and the second graphic is chemically decomposable because it is a compound. I prefer the first graphic because I think it is the easiest to understand. It very clearly shows that the mixture is hetero-geneous.
