1. Welcome to Chemistry II – Day VIII
Portland Evening Scholars
Mr. Treothe Bullock – Instructor
 Reaction Types
Have worksheet done – Notes
Jigsaw
 Chapter 8 Review
Should be completed and ready to
sign
We will go over
 Potential Energy Diagrams and
Chemical Reactions
Practice reading diagrams
 We will start Unit 9 Stoichiometry next
week
 Final Project Presentations
Begin Tonight!
 Email a copy of your presentation
to tbullock@pps.net
 Complete a self scoring on the
rubric and have ready to turn in
before starting
 Net Ionic Equations for double
replacement reactions
 Powerpoint notes and practice
 Solubility rules and how they help
predict reactions
 Absolute Zero

2. ?
 What are the
possible ways that
chemicals can react
together?

3. ?
Who gets first dibs when
chemicals have a chance to
hook up?
Why would any element have
to surrender to another?

4. Test Recovery
If you scored under 90% and would like to improve your grade
follow the steps below. 89% is the highest grade allowed on
recovered tests. ½ Credit is given for all questions corrected as
instructed.
 I. State what your
mistaken question and
answer were.
 II. Explain the thinking
error that caused you to
miss the question.
 III. State the correct
answer.
 IV. Justify your answer
with a reference in the
text. Show any work
necessary to solve the
problem.

5. Tutorial Extra Credit – 15 points
 I. Prepare questions you have for tutor – a
minimum of 1 question from each of the 3
levels.
 II. Take at a minimum of 1 page of notes
from tutorial session.
 III. Have a signature from the tutor
confirming your work with them.

6. Types of Chemical Reaction
 Synthesis Reactions
 A + X  AX
 Elements with Oxygen and
Sulfur
 Reactions of Metals with
Halogens
 Synthesis Reactions with
Oxides
 Decomposition Reactions
 AX  A + X
 Binary compounds
 Metal Carbonates
 Metal Hydroxides
 Metal Chlorates
 Acids
 Single Replacement
Reactions
 A + BX  AX = B
 Or
 Y + BX  BY + X
 Replacement of
 A Metal in Compound by
another Metal
 Hydrogen in Water by a
Metal
 Hydrogen in an Acid by a
Metal
 Halogens

7. Types of Chemical Reaction
 Double Replacement Reactions
 AX + BY  AY + BX
 Formation of a
 Precipitate
 Gas
 Water
 Combustion Reactions – A substance
combines with Oxygen releasing a large
amount of energy in the form of light and
heat
