Organic Chem Quiz
Translating/Balancing Quiz
I am going to do a Re-Do session on Monday for
the Translating/Balancing Quiz. If you come,
you may take a NEW quiz on Tuesday, after
school, or before school by Tuesday.


If you can’t come to the Monday Re-Do session, you
MUST come before school two days for help.
You MUST let me know that you’re interested by
Thursday!!!!
Types of Reactions
Research

You have been assigned a type of chemical
reaction. You have done research to define and
get important information about that reaction.

Next, you will meet with a group and share your
information.

Then, your group will come up with an analogy
to explain the different types of reactions.

Types of Reactions –
Analogies

Your group will come up with an analogy to
explain the different types of reactions.

Let’s share some!
Types of Reactions
Assessment
A + B  AB
Synthesis
A free element reacts with a
compound to form a new
compound and to release one
of the elements of the original
compound
Single Replacement
(Single Displacement)
3 CaCl2 + 2 AlN 
2 AlCl3 + Ca3N2
Double Replacement
(Double
Displacement)
2 KI + Cl2  2 KCl + I2
Single Replacement
Synthesis
Two ionic
compounds react to
form two new ionic
compounds;
“switching partners”
AB + CD  AC + BD
Double Replacement
(Double
Displacement)
AB + C  AC + B
Single Replacement

ONE compound breaks down into simpler
substances

General Equation: AB  A + B
Decomposition

Practice

pg. 14 – Types of Reactions

Using your notes, balance the equation and then
predict the type of reaction that the equation
represents.
Exit Ticket

Identify the type of reaction:


C10H8 + 12 O2 10 CO2 + 4 H2O
Mg + 2 H2O  Mg(OH)2 + H2
2 H2O  2 H2 + O2
8 Fe + S8  8 FeS
PbNO + 2 KI  PbI + 2 KNO
