  1. What’s the MATTER Classify Matter

  2. Matter, Classify MatterAt the conclusion of our time together, you should be able to: Classify a mixture of matter based on their physical and chemical properties Characterize various types of matter

  3. Bill Gates' RulesHere is a list of 11 things that many high school and college graduates did not learn in school. In his book, Bill Gates talks about how feel-good, politically-correct teachings created a full generation of kids with no concept of reality and how this concept has set them up for failure in the real world. RULE 9 Life is not divided into semesters. You don't get summers off and very few employers are interested in helping you find yourself. Do that on your own time.

  4. Types of Matter • Pure Substance- • Matter with a fixed composition • It has distinct properties • Examples = elements compounds

  5. Types of Matter • Mixtures- • Most matter is a mixture • The composition is not fixed (changes from sample to sample) • Two Types – Homogeneous Heterogeneous

  6. Homogeneous Mixtures • Composition is uniform throughout • Solution- • Particle size = 0.01 – 1 nm • Doesn’t settle out upon standing • Can’t be separated by filtering • Doesn’t scatter light • Example = salt water

  7. Homogeneous Mixtures • Colloid- • Particle size = 1 – 1000 nm • Doesn’t settle out upon standing • Can’t be separated by filtering • Scatters light (Tyndall Effect) • Examples = milk, gelatin, smoke

  8. Heterogeneous Mixtures - Suspension • The sample varies in composition, properties and appearance • No uniformity • If a suspension: • Particle size is greater than 1000 nm • Particles settle out upon standing • Can be separated by filtration • Might scatter light • Examples = soil, trail mix, pond water

  9. Don’t Let This Stuff Bite You!!!!

  10. Let’s Look at Some Examples: • Mixtures are variable combinations of 2 or more pure substances. Heterogeneous –visibly separate phases Homogeneous – Same throughout

  11. Pure substance vs. Mixture Only ONE element has 2 or more or compound. elements/ (distilled water) compounds.

  12. Distilled Water is a compound. an element. a solution. a mixture.

  13. Things my Mother taught me… LOGIC.      "Because I said so, that's why."

  14. Air is a mixture of several gases. Name Formula amount Nitrogen N2 78 % Oxygen O221 % Argon Ar1 % Carbon CO2 0.03 % Dioxide

  15. Air is a mixture of several gases Name Formula Amount Neon Ne 0.002 % Methane CH40.0002 % Helium He 0.000524 % Krypton Kr 0.000114 % Hydrogen H20.00005 % Xenon Xe 0.0000087 % Noble (inert) Gas

  16. Atoms are NOT the same as molecules. • Air and oxygen are NOT the same. • Helium and hot air are NOT the same.

  17. Helium and hot air are NOT the same.

  18. Another Hittite Innovation A Better Porta-Pot

  19. What’s the MATTER Classify Matter Let’s Put it All Together in a Chart!!

  20. MIXTURE PURE SUBSTANCE Yes No Is the composition uniform? Can it be chemically decomposed? No Yes Suspensions MATTER No Yes Can it be physically separated? Homo-geneous Mixture (solution) Hetero-geneous Mixture Compound Element Colloids

  21. Solution Solvent Solute H2O NaCl

  22. O E R SolVentSolUte The chemical The chemical in a solution in a solution that makes up that makes up the greatest part. the least part. N D E R

  23. Interesting Answers to Catholic Elementary School Bible Questions: The seventh commandment is: “Thou shalt not admit adultery.”

  24. Solvent Concentration the amount of solute dissolved in a solvent. Solute Low------------------- High dilute dy loot concentrated

  25. Solubility -how likely it is for a solute to dissolve in a solvent. insoluble soluble Low High

  26. Solvent Solute Crystal The Solution Process Legend Cation Anion Salt Water

  27. Several Types of Solutions • Salt in water • 3M HCl • Seltzer water • Alloys • Air • Humid air • Solid/liquid • Liquid/liquid • Gas/liquid • Solid/solid • Gas/gas • Liquid/gas

  28. I don’t feel so stupid now…

  29. Matter, Classify MatterLet’s see if you can: Classify a mixture of matter based on their physical and chemical properties Characterize various types of matter

  30. Putting sand and salt together makes a compound. an element. a mixture. a solution.

  31. Pure Water is a compound. an element. a solution. a mixture.

  32. Tap Water is a compound. an element. a solution. a mixture.

  33. Familiar Saying A beholden vessel never exceeds 212 degrees Fahrenheit. A watched pot never boils!

  34. An atom is to an element, as a molecule is to a metal. nonmetal. metalloid. compound.

  37. Which of the following illustrations represents a pure substance?

  38. To: Santa Re: Where Are My Gifts?!Actual E-mails to EmailSanta.com • I’m sorry, but I don’t have a chimney…I’ll leave the cat flap unlocked for you, but please watch out for the litter box! • Jon, 4

  39. Salt (NaCl) is a common substance. Salt is which of these? atom element compound mixture
