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
