2. Matter and Metrics Unit 1; Notes #2

3. What is Chemistry?

4. The study of the composition of substances and the changes they undergo.  Organic  Physical  Analytic  Biochemistry  Inorganic

5. Organic Chemistry The study of living system molecules: carbohydrates lipids nucleic acids proteins

6. Physical and Analytical Chem Highly focused on experimental data Upper level college chemistry

7. Biochemistry Where chemistry meets biologyWhere chemistry meets biology The chemistry of living systemsThe chemistry of living systems

8. Inorganic Chemistry Study of elements and compounds States of matter Reactions This IS high school chemistry!

9. Pure versus Applied Science Pure science is neither “good” nor “bad”, knowledge for fun of it Applied science = technology and engineering

10. Matter Anything that has volume and mass.

11. Volume: takes up space

12. Weight is a measure of gravity! Mass: measure of amount of matter, does not change with location

13. States of matter- Solids Have definite shape Have definite volume

14. States of matter-Liquids Fixed volume Pours or flows Takes shape of container In Swedish: Kvicksilver

15. States of matter-Gases Takes the shape of container Volume and density change with temperature

16. Periodic Table The elements can exist alone or bonded. Elements can be an atom or molecule. Compounds are molecules that are bonded elements.

17. Atom or Molecule? H 2 Mg F 2 S 8 Cu Molecule: two or more atoms chemically bonded Atom: smallest package of matter, single symbol

18. Element or Compound? O 2 NaCl CO 2 Pt H 2 O He Elements are the purest form of matter, only one type of atom. Compounds are two or more types of atoms chemically bonded to form a pure substance. Which of the above are atoms? Molecules?

19. Metric System SI = uniform system based on units of 10 Base units = defined unit on an object or event in physical world Quantity vs. Number 10,000 Base unitQuantity KilogramMass LiterVolume MeterDistance

20. Metric Conversions Kilo k Hecto h Deca da Meter m Gram g Liter L Deci d Centi c Milli m

21. Metric Equivalents mm daL kg dm cc L Millimeter Decaliter Kilogram decimeter cubic centimeter cm 3 = mL liter = dm 3
