Elements, Compounds & Mixtures Day 2 fall 2012

  1. 1. You Will Need: 1. Pencil, Red Colored pencil 2. Elements, Compounds and Mixtures – Picked up yesterday
  2. 2. Test #3 Retakes 1. 1 opportunities remainUpdate Log #4 1. Assignment Log #4 – Update w/new assignment
  3. 3. 1. What families make up the Transition Metals?2. Where would I find the Halogens on the P.T.?3. What is the valence of Silicon?4. What subatomic particle determines the charge of the atom?5. When an atom is “charged”, what do we call this particle?
  4. 4. 6. How are Elements and Compounds different?7. How are Elements and Compounds the same?8. Why are mixtures not “pure”?9. Name any 3 ways to separate a mixture?10.What does having a “set ratio” mean for compounds?11.If I am looking at B10, B11 and B12, how do I know the atom is Boron?
  5. 5. 13.If I have dissolved 3.5 mL of HCl in a solution containing 165 mLof H2O, which component of this mixture is the solute and which is the solvent? How do you know?14.Give an example of a heterogeneous mixture.15.Give an example of a homogeneous mixture.16.How are these two types of mixtures similar?
  6. 6. 17.KNO3 = element, compound or mixture?18.Bronze = element, compound or mixture?19.Hamburger = homogeneous or heterogeneous mixture? Why?20.What is the valence of Na and what family does this element belong to?21.What is the valence of Barium?22.Which family is the most reactive nonmetals on the P.T.? Why?
  7. 7. Pg.1 of Elements, Compounds & MixturesDraw a RED line between COMPOUND and MIXTURE
  8. 8. Look at the particles for each type of matter….Why did we draw a red line to separate the left from the right side of the chart?
  9. 9. Compound
  10. 10. Mixture
  11. 11. In Charge of Leading Discussion 1. Log into Learning Point 2. Daily Assignments 3. This Week 4. Open “Elements, Compounds and Mixtures” slide share 5. Use your abbreviation skills 6. R & R on pgs. 1,2 & 3
  12. 12. Elements are pure substances made of only one kind of atom.As we have learned, atoms are tiny structures found in all matter.Most substances contain many different atoms. It is how those atoms are arranged that determine whether you have an element, compound or mixture.
  13. 13. 1. One kind of atom2. Pure (because all particles are the same)3. Smallest particle to retain identity of the element4. Separated only in nuclear reactions
  14. 14. Particles look like: Every atom looks8 exactly the same 8 w/ the same 8 number of protons Oxygen 1 1 1 Hydrogen
  15. 15. Example: Aluminum: Every atom of aluminum in this can is exactly the same Your Example?
  16. 16. 1. Two or more kinds of atoms chemically bonded2. Pure (because all particles are the same)3. Smallest particle to retain the identity of the compound (SET RATIO of particles) CO4. Separated or rearranged in chemical reactions 2
  17. 17. Particles look like: Every compound looks exactly the same w/ the same set ratio Carbon Dioxide – CO2 Sodium Chloride - NaCl
  18. 18. Example: Salt: Every molecule of the compound NaCl is exactly the same Your Example?
  19. 19. 1. Two or more elements and/or compounds blended together physically2. Not pure (because all the particles are not the same)3. Separation through distillation, magnetic, evaporation, density, or particle size4. No set ratio
  20. 20. Particles look like: Each particle keeps its own identity….they are just “blended” together Mixture #1 Mixture #2
  21. 21. Examples: Heterogeneous: Different components are easy to see in this type of blending Homogeneous: Different components are difficult to see because they are evenly distributed Your Examples?
  22. 22. Categorize as either Atom, Element, Molecule or Compound
  23. 23. A solution is a mixture where all the components blend together to look like one substance.A solution is a homogeneous mixture that appears to be a single substance.The solution is composed of particles of two or more substances that are distributed evenly among each other and have the same appearance and properties throughout.
  24. 24. 1. In solutions, the SOLUTE is the substance that is being dissolved and usually is the smaller quantity in the mixture.2. The SOLVENT is the substance in which the solute is dissolved and usually is the larger quantity in the mixture.3. It is the SOLVENT that is doing the dissolving.
  25. 25. • Homogeneous: 2 or more things evenly blended and disappear into each other.• Solute – Smaller quantity by %• Solvent – Larger quantity by %• Solution – a homogeneous mixture
  26. 26. Have you ever put sugar into lemonade and seen the grains of sugar sink to the bottom and not dissolve?This is because the lemonade (solution) is supersaturated. In other words, there is not enough water (solvent) to completely dissolve the sugar (solute).Temperature and Pressure can affect saturation levels.
  27. 27. Saturation Level What does this What does this look mean? like? (color)Unsaturated •Mixture contains more solvent than solute •Able to dissolve more soluteSaturated •Mixture contains the % of solute completely dissolved by solvent •No able to dissolve more soluteSupersaturated •Mixture contains the % of solute unable to be dissolved by the % of solvent at the given temp. High temp usually = higher solubility
  28. 28. • Heterogeneous: 2 or more things put together and still can be seen.• No set RATIO.
  29. 29. Discuss and Generate 3 bullets ofinformation.Turn to pgs 144-145 in your text book.There you will find a chart with examples ofdifferent solutions having different states.Complete the chart.When coming up with your example, youmay discuss as a group and use thesame example .
  30. 30. 1. We now know the definition of Element, Compounds & Mixtures2. What do their particles look like?
  31. 31. 1. Elements, Compounds & Mixtures - To be “on-time” Pgs. 1-42. Have a good weekend!
