CLASSIFYING MATTER • Has mass • and volume. • Made up of two • or more different • particles/ • substances • mixed together. matter • Made up of only • onetype of • particle. mixture pure substance element compound heterogeneous mixture homogeneous mixture • Made up of • all the same • particles • called atoms. • Made up of all the • same particles called • moleculeswhich are • two or more different • atoms that arecombined • in fixed proportions. • Made up of • different • particles • which blend • well and are • uniformly • distributed.

19. heterogeneous mixture • Made up of different particles which • are ______________________. NOT uniformly distributed • The different particles are so large that • they do NOT evenly mix with one • another (e.g. salt and pepper mixture) or they are chemically unable to mix with one another (e.g. oil and water). However, some appear as if they are evenly mixed even when they are not (e.g. paint).
