Matter

1
Matter

• Has Mass and Takes Up Space

2
Mixture

• Varying composition
• Not Chemically Combined
• Retain properties of original substance
• Separate by physical means

3
Mixture

• Homogeneous
• Uniform throughout
• Examples
• ice tea
• stainless steel
• brass
• jar of peanuts
• gold jewelry

4
Homogeneous Solutions

• Solution
• Mixture in which particles are so small they
  cannot be seen and will not settle to the bottom
  of their container.
• Examples
• ice tea
• Windex
• Kool-Aid
• Coca Cola
• vinegar

5
Mixture

• Heterogeneous
• Not Uniform throughout
• Examples
• trail mix
• concrete
• dirt
• wood
• milk

6
Heterogeneous Colloids and Suspensions

• Colloid
• Mixture in which a beam of light can be seen as
  it passes through
• Examples
• Fog
• Milk
• gelatin

• Suspension
• Liquid heterogeneous mixture in which visible
  particles settle
• Examples
• muddy water
• Pepto Bismol
• chocolate in milk

7
Pure Substance

• Constant composition
• Chemically Combined
• Separated by chemical means

8
Pure Substances

• Elements made of one type of atom

9
Pure Substance

• Compounds fixed proportion of 2 or more elements

10
Physical Propertiescan be observed without
changing the composition of the substance
11
Physical Property Means of Separation

• viscosity (fluidity) ex. syrup v. wateruse
  decanting to separate

12
Physical Property Means of Separation

• conductivity ex. metal v. plasticuse electric
  charge to separate

13
Physical Property Means of Separation

• density ex. bowling ball v. basket ball use
  decanting chromatography to separate

14
Physical Property Means of Separation

• solubility ex. sugar v. pepper use
  dissolving evaporation to separate

15
Physical Property Means of Separation

• magnetism ex. iron v. wood use magnetic
  separation to separate

16
Physical Property Means of Separation

• melting/boiling point ex. water v.
  copperuse distillation to separate

17
Physical Property Means of Separation

• particle size ex. Sand v. boulders use
  filtering or screening to separate

18
Chemical Property

• If a substance will or will not undergo a change
  that will alter the composition of the original
  substance.

19
Chemical Properties

• Combustibility/Flammabilityhow easily a
  substance will burn

20
Chemical Property

• Oxidation - Combines with Oxygenex. Iron rusting

21
Chemical Property

• Corrode - to deteriorate due to the action of
  water, air, or an acid

22
Chemical Property

• Decomposition a compound broken into its
  elementsex. Hydrogen peroxide to water hydrogen

23
Chemical Properties

• React with Acidsex. Copper with nitric acid

24
Chemical Property

• Non-reactiveex. Gold, noble gases
