  • 1. Welcome to Chemistry II – Day VIIIPortland Evening ScholarsMr. Treothe Bullock – Instructor Reaction TypesHave worksheet done – NotesJigsaw Chapter 8 ReviewShould be completed and ready tosignWe will go over Potential Energy Diagrams andChemical ReactionsPractice reading diagrams We will start Unit 9 Stoichiometry nextweek Final Project PresentationsBegin Tonight! Email a copy of your presentationto tbullock@pps.net Complete a self scoring on therubric and have ready to turn inbefore starting Thomas, Ryan, George, Hai,Weiton Net Ionic Equations for doublereplacement reactions Powerpoint notes and practice Solubility rules and how they helppredict reactions Absolute Zero
  • 2. ? What are thepossible ways thatchemicals can reacttogether?
  • 3. ?Who gets first dibs whenchemicals have a chance tohook up?Why would any element haveto surrender to another?
  • 4. Test RecoveryIf you scored under 90% and would like to improve your gradefollow the steps below. 89% is the highest grade allowed onrecovered tests. ½ Credit is given for all questions corrected asinstructed. I. State what yourmistaken question andanswer were. II. Explain the thinkingerror that caused you tomiss the question. III. State the correctanswer. IV. Justify your answerwith a reference in thetext. Show any worknecessary to solve theproblem.
  • 5. Tutorial Extra Credit – 15 points I. Prepare questions you have for tutor – aminimum of 1 question from each of the 3levels. II. Take at a minimum of 1 page of notesfrom tutorial session. III. Have a signature from the tutorconfirming your work with them.
  • 6. Types of Chemical Reaction Synthesis Reactions A + X  AX Elements with Oxygen andSulfur Reactions of Metals withHalogens Synthesis Reactions withOxides Decomposition Reactions AX  A + X Binary compounds Metal Carbonates Metal Hydroxides Metal Chlorates Acids Single ReplacementReactions A + BX  AX = B Or Y + BX  BY + X Replacement of A Metal in Compound byanother Metal Hydrogen in Water by aMetal Hydrogen in an Acid by aMetal Halogens
  • 7. Types of Chemical Reaction Double Replacement Reactions AX + BY  AY + BX Formation of a Precipitate Gas Water Combustion Reactions – A substancecombines with Oxygen releasing a largeamount of energy in the form of light andheat
