2. Warm Up Interpreting Formulas
Substance
Element or Compound
# atoms of each element
Al2O3
Compound
Al=2, O=3
Na2SO4
CaSO4 Fe
C2H6 N2 O3

3. 8.P.1 Understand the properties of matter and changes that occur when matter interacts in an open and closed container. 8.P.1.1 Classify matter as elements, compounds, or mixtures based on how the atoms are packed together in arrangements.

4. Students will: Identify physical processes and properties involved in separating mixtures, plan separation procedures for several mixtures, test those procedures and assess their success.

5. p 11
Mixtures
Are made of components that are physically combined, e.g. ink, fizzy drinks, crude oil, air
The components of a mixture can be separated by several methods or techniques
Each separation technique makes use of differences in the physical properties of the components

7. Separating Mixtures What processes are used?
Compounds
Elements
Homogeneous
(solutions)
Heterogeneous
Evaporation LG
Distillation – uses the different boiling points of components to separate a solution
(evaporation followed by condensation)
Sifting
Filtering
Separate using chemical reactions
components are chemically combined
Cannot be broken down into simpler substances.

8. Separating Mixtures Mini Lab
Process used (sifting, filtering, magnetism, distillation)
Physical property exploited (boiling point, magnetism, size, solubility)
Aluminum (Al), Iron Filings (Fe)
Use magnetism  Fe sticks to magnet, Al does not
Magnetism is the physical property used
Rocks, sand
groups brainstormed and completed this process
Salt, sand
Add H2O to the mixture  Salt dissolves, sand doesn’t [physical property = solubility]
Pour mixture through filter  sand remains, salt and water go through. [physical property used = size]
Boil/Evaporate salt water  water evaporates, salt remains [physical property used = boiling point]
Salt, sand, iron filings
