  1. Classification of Matter BHS - Chemistry

  2. Matter

  3. Matter

  4. Matter Can it be separated physically? Mixture A blend of two or more kinds of matter, each which retains its own identity and properties.

  5. Mixture • A blend of two or more kinds of matter, each which retains its own identity and properties. • In this example: • Piña colada still retains piña colada identity • Blueberry still retains blueberry identity • Can be separated into distinct parts

  6. Matter Can it be separated physically? Pure Substance Mixture A blend of two or more kinds of matter, each which retains its own identity and properties. Has a fixed composition with exactly the same characteristic properties.

  7. Pure substance Has a fixed composition with exactly the same characteristic properties. Example: Sugar (sucrose) - A sugar molecule always has 12 Carbon, 22 Hydrogen, and 11 Oxygen atoms bonded together

  8. Matter Can it be separated physically? Pure Substance Mixture A blend of two or more kinds of matter, each which retains its own identity and properties. Has a fixed composition with exactly the same characteristic properties. Is the composition uniform? Homogenous Mixture

  9. Homogeneous • Both “homogeneous” (ho-mo-gee-nee-us) and “homogenous” (ho-mah-gen-us) are acceptable pronunciations

  10. Examples • Air • Sugar in water • Stainless steel – carbon, chromium, nickel

  11. Matter Can it be separated physically? Pure Substance Mixture A blend of two or more kinds of matter, each which retains its own identity and properties. Has a fixed composition with exactly the same characteristic properties. Is the composition uniform? Heterogeneous Mixture Homogenous Mixture • Examples: • Air • Sugar in water • Stainless steel

  12. Heterogeneous • Heterogeneous: • Both acceptable: (het-er-uh-gee-nee-us) (het-er-uh-gee-nyus)

  13. Examples • Granite • Quarts • Mica • Feldspar • Wood • Blood

  14. Wood • Wood • Cellulose • Hemicellulose • Lignin

  15. Blood • Blood • White cells, • Red cells • Platelets • Plasma

  16. Matter Can it be separated physically? Pure Substance Mixture A blend of two or more kinds of matter, each which retains its own identity and properties. Has a fixed composition with exactly the same characteristic properties. Is the composition uniform? Can it be decomposed by ordinary chemical means? Heterogeneous Mixture Homogenous Mixture Compound • Examples: • Air • Sugar in water • Stainless steel • Examples: • Granite • Wood • Blood

  17. Compound • Examples: • Water (H2O) • Sodium chloride (NaCl) • Sucrose (C12H22O11)

  18. Matter Can it be separated physically? Pure Substance Mixture A blend of two or more kinds of matter, each which retains its own identity and properties. Has a fixed composition with exactly the same characteristic properties. Is the composition uniform? Can it be decomposed by ordinary chemical means? Heterogeneous Mixture Homogenous Mixture Compound Element • Examples: • Air • Sugar in water • Stainless steel • Examples: • Granite • Wood • Blood • Examples: • Water • Sodium chloride • Sucrose

  19. Element • Examples: • Gold (Au) • Aluminum (Al) • Oxygen (O) • Chlorine (Cl)
