Collect
In-Class Assignment
Take some time to finish the “Chemical
Formulas and Equations” worksheet in class.
Side 329: #1-14
Side 330: #21-30
The worksheet is due TODAY!
Section 8.3 Quiz
“Classifying Chemical Reactions”
You may use your book and your guided notes
to complete the quiz on your own.
When you finish,
turn it in, pick
up the lab handout
and start reading it
through…
Lab: “Classifying Chemical
Reactions”
Get together with your 3:00 lab partner…
Lab: “Classifying Chemical Reactions”
First, make a new “Table of Contents” page for
your lab folder.
Table of Contents
Title of Lab

Lab #

Lab: “Classifying Chemical Reactions”
Hints
You don’t have to do the Pre-Lab questions.
(you’re welcome!) 
You will NOT be doing the optional “Classifying
Chemical Reactions Worksheet” mentioned in
item #3 on the very last page…at least not
right now…
Lab: “Classifying Chemical Reactions”
Discussion
This lab consists of 7 separate reactions that
you will conduct and analyze.
Reactions will be set up at the lab tables and
you will rotate through. (Just like when you did
the flame-test lab in Chem 1)
Read the lab carefully, especially the
background information and safety
precautions.
Lab: “Classifying Chemical Reactions”
Changes to Materials List:
1. Delete “ammonium carbonate”.
2. Change “bunsen burner or laboratory
burner” to bunsen burner and striker.
3. Change “forceps or crucible tongs” to
crucible tongs.
4. Change “heat-resistant pad” to wire gauze.
5. Change “pipets, Beral-type” to dropper.
 Everything else stays the same…
Lab: “Classifying Chemical Reactions”
Changes to Procedure
1. You WILL NOT be doing Reaction #3.
 Ammonium carbonate needs to be used in
the hood but the hood will have Reaction
#8 set up in it.
2. However, you still need to answer the postlab question associated with Reaction #3 on
the back page of the lab handout.
**Hint: products are ammonia (NH3),
carbon dioxide (CO2), and water.**

Write-Up
The lab write-up is a little different this year:
1. Title
2. Purpose
3. Hypothesis
4. Materials
5. Procedure
Reflection Statement
 Should be the last paragraph in your lab.
Reflection Statement
The reflection statement is a paragraph statement
that you’ll write after the completion of the lab.
 In it, the following items should be addressed to
receive full credit:
1. Was your hypothesis correct?
2. What were some possible sources of error in the lab?
3. How could these sources of error be reduced in
future trials?
4. Did this lab help you understand the material we’ve
been covering?

Write-Up
You have the remainder of the class period to
work on your lab write-up.
You may work with your lab partner if you’d
like.
Write-ups will be checked for completion prior
to the lab.
This is a great lab to reinforce the different
types of chemical reactions we talked about.
Looking Ahead
Thursday/Friday is lab day, no flip-flops!
NO SSA = NO LAB!
Chapter 8 test/concept review due:
Friday, Sept. 20th: “A” Day
Monday, Sept. 23rd: “B” Day
