Matter
Matter
Matter
Mixture
Can it be separated physically?
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
Mixture Pure Substance
Can it be separated physically?
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
Mixture Pure Substance
Homogenous
Mixture
Can it be separated physically?
Is the composition uniform?
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.
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

Mixture
Can it be separated physically?
Is the composition uniform?
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.
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
