Mixtures can be heterogeneous or homogeneous. Give two examples of each type. Explain why you classified each example as you did.
Chem 131 (10/24/16-11/4/16) Intro: here are the notes I’ve taken during Prof. Ondov’s lecture and from the textbook Chemistry: Structure and Properties 6th e ition by Nivaldo J. Tro Chapter 8: Chemical Reactions 8.1 chemical change- original substance transforms and matter of composition changes (eg. iron rusting, sugar burning, photosynthesis) ➢ Chemical Properties: corrosiveness, flammability, toxicity, acidity, etc. ➢ Usually indicated by temperature or color change physical change- original substance alters state of matter, not composition (eg. ice melting) ➢ Physical Properties: odor, taste, color, appearance, melting point, boiling point, etc. ➢ Usually indicated by change in state of matter or physical condition of matter 8.2 Chemical Equations stoichi
