Welcome
to Chemistry 1B. This course in the second half of the General Chemistry course offered at
RCC. This semester we will cover the topics: rates of reaction, chemical equilibrium, acid
-
base
chemistry, thermochemistry(entropy and free energy), electrochemist
ry, transition, organic
and nuclear
chemistry. The first 5 topics we will cover in detail the last two will not be covered extensively but we you
will be exposed to major concepts.




Course Schedule:

Required Textbooks:

• Lecture:
Chemistry: A Molecular Approach
,
1st ed
., by Nivaldo J. Tro.

• Laboratory:
Experiments in General Chemistry
, by Amrich et.al.

Required:

Periodic Table, Scientific Calculator with Exponential and Log functions
(You
may NOT use a programmable calculator or a cell phone on the tests.)

You will need to bring a pencil, paper and calculator to class each day
.

If you
are not willing to do the practice problems in class you will be asked to leave.


Objectives
.

We are going to work on being logical, thinking critically and applying knowledge in a
broader manner. You will need to be able to use the information y
ou learned in chemistry 1A as well as
knowledge from this class to answer questions. By the end of the class you will take the initiative in
learning, You will do your homework, come to see me and use the computer and school tutorials without
prodding. Yo
u will learn to actually think about what you are doing in the laboratory and whether your
answers make sense before you turn in your work. You are becoming scientists it is time to start thinking
like one.


Learning Outcomes
:

Upon successful completion o
f the course, students should be able to:

1.

Solve multi
-
step problems (using formulae and unit
-
analysis) relating to kinetics, equilibria,
thermodynamics, electrochemistry, and other course content.

2.

Collect and analyze data from chemical experiments,
including graphing, calculations, and qualitative
understanding of how data relates to the concept studied.

3.

Construct and manipulate equipment to secure reasonably accurate

measurements.

4.

Describe

and apply chemical concepts of kinetics, equilibria, thermod
ynamics, and electrochemistry.

5.

Describe and apply a chemical vocabulary of approximately
300

words
and apply IUPAC
nomenclature.

Homework and Quizzes
: Homework will be assigned but not collected.

There will be 6 quiz
z
es during
the semester. Questions will be taken directly from Tro 1st edition.



Handouts

Handouts are group work
. These will be included in with your quiz grades

Exams

There will be
2

exams during the semester each worth 100 points and a comprehensive f
inal that
will be
55
% from the material from the last exam and 50% material from the beginning of the semester

on
the last day of class worth 200 pts
. NO EXAM GRADES WILL BE DROPPED
. Exams are multiple
choice, fill in, true/false and any other kind of que
stions I find interesting.

Missed work
: Missed quizzes and Handouts CANNOT BE MADE UP. If you miss an exam
you must
make up the exam the next class period and you must have a doctor's note
. If you miss more than 1
exam I suggest you drop the class becaus
e
that exam cannot be made up. NO

MATTER WHAT THE
CIRCUMSTANCES.

Homework schedule

Summer

12

Chemistry 1B is a 5 unit class. This means that you are expected to do 2
-
3 hours of studying for each 1
hour of lecture. Do as many problems as possible. Homework is very likely to show up on quizzes and
exams. I recommend you form study groups, make f
riends you can call when you are struggling with a
problem. Homework problems are at the back of each chapter. The answers to the blue questions are in
the back of the book.
