Everything we know about molecules:
Statement A: All molecules of one substance are exactly the same, and they are different from molecules of any other substance.
Statement B: The properties of the molecules of a substance do not change.Read the explanation for this model below and review the diagram of the model on the next page. 2. Turn to pages 28–29, Evaluating Chromatography Models, and discuss each question with your partner. • On page 28, circle Ye s or No for each question to indicate if it does or does not explain what you observed in chromatography and what you know about molecules.
