  1. WARM - UP • Update your Table of Contents • Write your homework – leave it to be stamped • Get your Review Packet out to be checked! • Quiz each other on the vocab list while you wait to be checked!

  2. Surface Area Increasing the surface area (by breaking something into multiple pieces) increases the reaction rate…HERE’S WHY: Wrap-Up: • Greater surface area = greater chance for collisions • More collisions = more/faster reactions taking place

  3. Temperature Increasing the temperature, increases the reaction rate…HERE’S WHY: Wrap-Up: • Higher temperature makes particles speed up = more collisions • More collisions = more/faster reaction taking place

  4. Pressure Increasing thepressure, increases the reaction rate…HERE’S WHY: Wrap-Up: • Particles have less space to move in = more collisions • More collisions = more/faster reactions taking place

  5. Concentration Increasing the concentration (amount of a substance) increases the reaction rate…HERE’S WHY: Wrap Up: • Putting MORE of a substance into the same amount of space = more collisions • More collisions = more/faster reactions taking place

  6. Catalysts Adding a catalyst increase the rate of reaction…HERE’S WHY: Wrap-Up: • Catalysts act as a “matchmaker” to jump start a reaction or make it faster • Catalysts are not affected or used during the reaction

  7. Does your class data table confirm these results?

  8. 1st Block Data Table (A-day)

  9. 3rd Block Data Table (A-day)

  10. 4th Block Data Table (A-day)

  11. 1st Block Data Table (B-day)

  12. 3rd Block Data Table (B-day)

  13. 4th Block Data Table (B-day)

  14. Ted Talks – Reaction Rates • http://ed.ted.com/lessons/how-to-speed-up-chemical-reactions-and-get-a-date • Answer the final question under Ted Talks – Reaction Rates

  15. Last Chance to Balance • Balance the 5 equations on the sheet – if you get them correct you will be using the Chromebooks for the remainder of class to complete the “Study Buddy Review” • If you get them incorrect you will be on the carpet in the front with me practicing how to balance equations.

  16. REVIEW • You can work with a PARTNER, as some games require 2 players • Play the review games listed on the sheet given to you and your partner…if you get through all of them ONLY then can you search for alternate CHEMISTRY RELATED sites

  17. EXPECTATIONS • I expect you and your partner to play only what you are supposed to without being disruptive in any way!! • When you are working with me you are expected to complete the equations

  18. Equation 1 - Balance Box Answer P + O P₄O₁₀

  19. Equation 2 - Balance Box Answer Cl₂ + NaBr NaCl + Br₂

  20. Equation 3 - Balance Box Answer Cs + N₂ Cs₃N

  21. Equation 4 - Balance Box Answer CuCl₂ + H₂S CuS + HCl

  22. Equation 5 - Balance Box Answer Al + HCl AlCl₃ + H₂

  23. Balancing Equations Practice Homework • Find the Balancing Equations Practice Homework or take another sheet – we will work on a few together, and then you can practice on your own.

  24. Na + MgF2 NaF + Mg Lets Practice: Part D - #1

  25. Cl2 + KI KCl + I2 Lets Practice: Part D - #2 IMPORTANT: Cl = Chlorine K & I are 2 separate elements

  26. HCl + NaOH NaCl + H2O Lets Practice: Part D - #3

  27. Na + NaNO3 Na2O + N2 Lets Practice: Part D - #4

  28. PbBr2 + HCl HBr + PbCl2 Lets Practice: Part D - #5

  29. REVIEW • Try 6, 7 & 8 on your own, and then check the answer key

  30. Na3P + CaF2 NaF + Ca3P2 Lets Practice: Part D - #6

  31. AlBr3 + K KBr + Al Lets Practice: Part D - #7

  32. CaF2 + Li2SO4 CaSO4 + LiF Lets Practice: Part D - #8
