Matter

Mixture

Can it be separated physically?

A blend of two or more kinds of matter, each which retains its own identity and properties.

Page 5: Classification of Matter BHS - Chemistry. Matter

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.

Page 7: Classification of Matter BHS - Chemistry. Matter

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.

Page 9: Classification of Matter BHS - Chemistry. Matter

Homogeneous

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

Page 10: Classification of Matter BHS - Chemistry. Matter

Examples

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