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? Mixture Pure Substance 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? Mixture Pure Substance 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 Mixture Pure Substance Homogenous Mixture Heterogeneous Mixture
Can it be separated physically? Mixture Pure Substance 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 Heterogeneous 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

Matter Can it be separated physically? Mixture Pure Substance 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? Homogenous Mixture Heterogeneous Mixture Compound Examples: Air Sugar in water Stainless steel Examples: Granite Wood Blood

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

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

Classification of Matter
Matter. What is matter? – Anything that has volume (takes up space) and has mass. So… what is mass? – Amount of matter that something contains Difference.

Classification of Matter. Pure Substances  every sample has the same characteristic properties & composition  ELEMENTS  one type of atom Ex: iron.
