5. Heterogeneous Mixtures Type of matter consisting of at least two parts physically combined Visible parts (phases) Varying composition Impure Physically separable

6. Heterogeneous Mixture Examples DirtHeterogeneous mixtures have more than one visible phase ConcreteCar

7. How to Decide Do you see only one part? (YES/NO) NOYES Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements

8. Homogeneous Mixtures Matter that is uniform throughout Referred to as a Solution 1 visible part (uniform distribution) Constant composition throughout Even distribution of particles

9. Solution (Homogeneous Mixture) Examples Salt waterBrass (A solution of metals=alloy) GlassSolutions appear to be one part, but are actually just mixed very well

10. How to Decide Is the matter pure? (YES/NO) NOYES Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements Is the matter pure?

11. Compounds Homogeneous matter that is made of more than one type of atom Constant composition Fixed ratio Pure 2 or more different elements in formula SUGAR Pure water

12. Compound Examples Table Salt (NaCl)Compounds are pure matter that consists of two or more different elements chemically combined Carbon Dioxide (CO 2 )Silver Nitrate (AgNO 3 )

13. How to Decide Is there only 1 type of element? (YES/NO) NOYES Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements

14. Homogeneous matter that consists of only 1 type of atom Constant composition Pure Only 1 element type in formula

15. Element Examples CarbonOxygen Elements are pure matter consisting of only one type of atom Uranium

16. How to Decide NOYES Is there only 1 type of element? (YES/NO) Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements

17. The Big Picture (click 3 times) Is there only 1 type of element? Is the matter pure? Do you see only one part? NO YES Heterogeneous Mixtures Homogeneous Mixtures Compounds Elements
