1. Introduction to Chemistry Matter

2. What is Chemistry? In your own words, please write down how you would define the following words: Biology Physics Chemistry

3. What is Chemistry? Biology Physics Chemistry The study of living organisms The study of forces & motion The study of matter and its reactions and properties

4. Matter

6. Elements Type of matter that cannot be broken down into simpler, stable substances and is made of only one type of atom

7. Compounds A pure substance that contains two or more elements whose atoms are chemically bonded

8. Compounds Fixed compositions  A given compound contains the same elements in the same percent by mass

9. Compounds The properties of a compound are VERY DIFFERENT from the properties of the elements they contain Ex.) Sodium Chloride (NaCl) vs. Sodium & Chlorine Sodium: http://www.youtube.com/watch?v=RAFcZo8dTcUhttp://www.youtube.com/watch?v=RAFcZo8dTcU http://www.youtube.com/watch?v=92Mfric7JUc

10. Electrolysis

11. Mixtures A blend of two or more kinds of matter, each of which retains its own identity and properties  Homogeneous  Heterogeneous

12. Homogeneous Mixtures Composition is the same throughout the mixture  Examples: salt water, soda water, brass A.k.a. a solution  Solute in a solvent (salt dissolved in water)

13. Heterogeneous Mixtures Non-uniform; composition varies throughout the mixture

14. Separating Mixtures Filtration

15. Separating Mixtures Distillation

16. Separating Mixtures Chromatography
