Classification of Matter BHS - Chemistry
Matter Can it be separated physically? Mixture A blend of two or more kinds of matter, each which retains its own identity and properties.
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
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.
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
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
Homogeneous • Both “homogeneous” (ho-mo-gee-nee-us) and “homogenous” (ho-mah-gen-us) are acceptable pronunciations
Examples • Air • Sugar in water • Stainless steel – carbon, chromium, nickel
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
Heterogeneous • Heterogeneous: • Both acceptable: (het-er-uh-gee-nee-us) (het-er-uh-gee-nyus)
Examples • Granite • Quarts • Mica • Feldspar • Wood • Blood
Wood • Wood • Cellulose • Hemicellulose • Lignin
Blood • Blood • White cells, • Red cells • Platelets • Plasma
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
Compound • Examples: • Water (H2O) • Sodium chloride (NaCl) • Sucrose (C12H22O11)
