COURSE GOALS AND STUDENT OUTCOME OBJECTIVES: This course will seek to develop a strong foundation of the basic concepts in chemistry. In particular, we will examine how physical properties of substances depend on their chemical structure and how these influence chemical reactions. This will require us to understand intermolecular forces, descriptions of solutions and models describing ions, acids and bases. We will also learn about thermodynamics and how these models can help us to predict energy flow for a reaction and whether or not it is possible for a reaction to occur spontaneously. The study of kinetics, the rate of chemical reactions, will not only help us to understand how fast, but will also help us to understand how reactions occur. An understanding of equilibrium will allow us to predict the amounts of reactants and products for a chemical system.
Demonstrate the proper use of the following:
a. The intermolecular forces and their effect on the physical properties of a compound or molecule.
b. How to make mixtures and solutions to a desired concentration using units of % mass, molarity, molality and mole fraction.
c. Properties of solutions including concentration units, principles of solubility and colligative properties.
d. Principles of heat flow, measurement of heat flow and calorimetry, enthalpy and enthalpies of formation, thermodynamic equations, bond dissociation energies, the first law of thermodynamics, and free energy.
e. Reaction rates and concentrations, reactant concentration and time and reaction mechanisms.
f. Equilibrium, the equilibrium constant expression, determination of equilibrium constants, applications of the equilibrium constant to problem solving, and the effects of changes in conditions upon an equilibrium system.
g. Acid-base theories, water ionization constant and its affect of pH and pOH, weak acids and weak bases and their affect on the pH of aqueous solutions, and the acid-base properties of salt solutions.
h. Buffer solutions and their affect on the pH of aqueous solutions, acid-base indicators, acid-base titrations, and polyprotic acids.
i. Precipitate formation, use of the solubility product constant (Ksp) to predict solubility, dissociation of precipitates, and qualitative analysis.
j. Electrochemistry, voltaic and electrolytic cells, effect of concentration on cell voltage, standard cell potentials, and batteries.
COURSE CONTENT:
We will cover chapters 10-19 of the text. Topics covered are intermolecular forces, solutions, equilibrium, kinetics, thermodynamics, electrochemistry and nuclear chemistry.
GRADING:
● Assignments (15%)
For each Chapter, homework assignments will be assigned through saplinglearning.com Assignments must be completed by the due date. . Do not wait until the last minute to start the assignment!
● Clicker questions (5%)
For each lecture, there will be 1-5 clicker questions. Each student will start the course with 15 bonus clicker points.
● Examinations (60%)
There will be three in-class exams-100 points each. These will occur on Sept. 20, Oct. 16 and Nov. 17. The lowest exam score will be dropped.
● Final (20%)
The final will be comprehensive with 20% over material covered after Exam 3 on Dec. 7th, from 8:00 – 10:00 a.m.
GRADING SCALE:
A = 90-100; B = 80-89; C = 70-79; D = 60-69; F< 60; P = 70 or above.
ATTENDANCE POLICY: Mandatory.
MAKE-UP POLICY: NONE
ACADEMIC HONESTY POLICY: Cheating or scholastic dishonesty will not be tolerated. In cases of academic dishonesty the instructor may dispose of the matter by invoking a maximum sanction of immediate expulsion from the course and the issuance of a failing grade. You work in groups for the experiment, but you write individual lab reports. Similar lab reports will be considered cheating.
ACADEMIC DISABILITY POLICY: If you have a documented disability that requires assistance, you will need to register with the Office of Disability Services for coordination of your academic accommodations. The Office of Disability Services is located in Peltier Hall, Room 100-A. The phone number is (985) 448-4430 (TDD 449-7002).
Classroom Behavior and Etiquette: Disruptive behavior will not be tolerated. This includes carrying on conversations with your neighbors during class. The use of cell phones during class time is prohibited. Please turn your cell phone off or silence it. If the phone rings during class time, leave the room and answer it and do not return until the next class. Cell phones must not only be off, but also put away during tests and exams. They may not be used as calculators.
Academic Grievances:
The proper procedure for filing grade appeals or grievances related to academic matters is listed in Section 5 of the Code of Student Conduct and at the following link:
http://www.nicholls.edu/documents/student_life/code_of_conduct.pdf.
Continued Learning following an Extreme Emergency:
In order to make continued learning possible following an extreme emergency, students are responsible for:
● reading regular emergency notifications on the NSU website
● knowing how to use and access Blackboard (or university designated electronic delivery system)
● being familiar with emergency guidelines
● evacuating textbooks and other course materials
● knowing their Blackboard (or designated system) student login and password
● contacting faculty regarding their intentions for completing the course
Faculty are responsible for:
● their development in the use of the Blackboard (or designated) software
● having a plan for continuing their courses using only Blackboard and email
● continuing their course in whatever way suits the completion of the course best, and being creative in the continuation of these courses.
● making adjustments or compensations to a student’s progress in special programs with labs, clinical sequences or the like only in the immediate semester following the emergency.

How to succeed in this chemistry class
1. Pre-read the reading assignment before class. Even if you only skim through the material you will benefit. Study key concepts, define key words and equations. These can be found at the end of each chapter.
2. Go to Class. Be prepared with questions to ask!
3. Before the next class, review the previous lecture. Take note of any questions or difficulties that you might have with the material covered.
4. If you have questions, make sure that they are answered before the next lecture. Come by and discuss these with me or with someone else.
5. Do all of the assignments before the due date! Print out the questions and work the out on paper before entering the answer on-line.
6. You should expect to spend at least six or more hours outside of class for this course. Plan your schedule accordingly!
