1. The Science of Matter Chapter 1

2. Chemistry
The science that investigates and explains the structure and properties of matter.

3. Matter & Mass Matter: Anything that takes up space and has mass.
Mass: The measure of the amount of matter that an object contains.

4. Properties
Properties of matter describe the characteristics and behavior of matter, including the changes matter undergoes.
Ex: Properties of Iron
rusts magnetic turns to a liquid

5. Macroscopic & Microscopic
Macroscopic: Matter that is large enough to be seen without a microscope.
You can touch, feel, taste and see these properties.
Microscopic: Objects seen with a microscope.
Atoms

6. Classifying Matter Qualitative:
An observation that can be made without measurement. Involves the analysis of data using words (heavy, blue, short, etc.)
Quantitative:
An observation that uses measurement.
Ex: Temperature = 71C
Mass = 15kg
Time = 24 seconds

7. Mixture: A physical blend of two or more substances that are not chemically combined.
Pure Substance: Matter with the same fixed composition and properties.

8. Pure Substance Mixture

9. Properties and Changes
Physical Change: A change in matter that does not involve a change in the identity of the substance.
Boiling, melting, dissolving,
Physical Properties: Characteristics of matter that can be observed or measured.
Freezing point, density, color, conductivity, physical state, etc

10. Heterogeneous Mixture: Does not have uniform composition and the individual substances remain separate.
Homogenous Mixture: Are the same throughout.

11. Mixtures Heterogeneous Homogenous Stainless Steel Gatorade Granite
M & M s

12. Homogenous Mixtures (Solutions)
Some solutions are solids.
Alloys are solid solutions that contain different metals.
Gold Jewelry GW Bridge

13. Solutions Solute: the substance being dissolved
Solvent: The substance that dissolved the solute
Final Product =

14. Methods of Separation of Mixtures
Distillation
Filtration
Magnetism

15. Distillation: -separate dissolved solids from a liquid -uses boiling and condensation.

16. Filtration: separates a solid from a liquid in a heterogeneous mixture

17. Example: Separate iron filings from sulfur using a magnet.

19. Elements, Compounds & Formulas
The simplest form of matter.
Cannot be broken down any further into simpler substances.
Ex: Ca, N, Fe, Ag, Br
Compounds:
A chemical combination of two or more different elements chemically joined together in a fixed proportion.
Ex: NaCl, H2O
Formula:
A combination of chemical symbols that shows what elements make up the compound and the number of atoms of each element.
