Syllabus for CHE-122

GENERAL CHEMISTRY II WITH LABS


COURSE DESCRIPTION

Chemistry is a science that deals with the composition, structure, and properties of substances and with the transformations that they undergo. It is the "study of change."

In this course, the second of a two-semester general chemistry sequence with labs, our emphasis is on chemical equilibrium, acid-base chemistry, and energy changes in chemical reactions. We also focus on chemical thermodynamics, kinetics, intermolecular forces and the physical properties of solutions, coordination compounds, and electrochemistry.

At the atomic and molecular level, chemistry is a very abstract subject, but the study of atoms and molecules is fundamental to understanding life itself, since all matter is made up of atoms and molecules. Through practical examples and applications, we hope to explain not only the abstract concepts of chemistry but also how we come to know and understand those concepts in real-life contexts.


Advisory: It is advisable to have knowledge in a course equivalent to CHE-121 General Chemistry I with a grade of C or better to succeed in this course.

COURSE OBJECTIVES

After completing this course, you should be able to:

  1. Differentiate intermolecular forces and relate these forces to the physical properties of liquids, solids, and solutions (boiling point, freeze/melt point, and vapor pressure).
  2. Describe the solution process and the properties of solutions.
  3. Calculate concentrations of solutions (molarity, molality, mass percent, and mole fraction).
  4. Summarize the concepts of chemical kinetics and interpret chemical reactions from kinetic data.
  5. Explain the concept of chemical equilibrium and the effect of Le Châtelier’s principle on equilibrium.
  6. Relate the properties and characteristics of acid-base solutions to reactions involving acids and bases.
  7. Calculate the pH of strong and weak acid solutions and mixtures involving buffers.
  8. Apply chemical equilibrium concepts to solubility.
  9. Discuss how the principles of chemical thermodynamics apply to processes of chemical and physical change.
  10. Apply oxidation-reduction reactions to electrochemical reactions.

ASSESSMENT METHODS

For your formal work in the course, you are required to participate in online discussion forums, complete written assignments and laboratory assignments, take unproctored module quizzes, and take two proctored online examinations: a midterm exam and a final exam. See below for details.

Consult the course Calendar for due dates.

Discussion Forums

You are required to participate in four (4) graded discussion forums, worth 10 percent of your course grade,  as well as an ungraded Introductions Forum. The online discussions are on a variety of self-selected topics associated with the course modules.

Communication among fellow students and with the mentor is a critical component of online learning. Participation in online discussions involves two distinct activities: an initial response to a posted question (discussion thread) and subsequent comments on classmates' responses. Meaningful participation is relevant to the content, adds value, and advances the discussion. Comments such as "I agree" and "ditto" are not considered value-adding participation. Therefore, when you agree or disagree with a classmate, the reading, or your mentor, state and support your agreement or disagreement. You will be evaluated on the quality and quantity of your participation. Responses and comments should be properly proofread and edited, professional, and respectful

For posting guidelines and help with discussion forums, please see the Student Handbook located within the General Information page of the course Web site.

Laboratory Assignments

General Chemistry II with Labs includes ten (10) laboratory assignments, worth 20 percent of your course grade. Each laboratory assignment asks you to complete experiments from an eScience lab (paying close attention to the instructions provided in the eScience Lab Manual) and then to submit a written Laboratory Report to the mentor for grading.

Laboratory Report assignment sheets, with all sections and questions typed out in advance for you, are provided. Be sure to include your name at the top of the paper, as well as the course name and code and the semester and year in which you are enrolled. Click General Instructions for guidelines on completing laboratory assignments.

Written Assignments

General Chemistry II with Labs has ten (10) written assignments, worth 20 percent of your course grade. The written assignments draw mostly on on odd-numbered questions and problems from the textbook. Answer all assigned questions and problems, and show all work. 

Assignment sheets, with all questions typed out in advance for you, are provided. Be sure to include your name at the top of the paper, as well as the course name and code and the semester and year in which you are enrolled. To receive full credit for your answers, you must show all work and include complete solutions.

For help regarding preparing and submitting activities, see the Student Handbook located within the General Information page of the course Web site.

Quizzes

You are required to take ten (10) module quizzes, worth 10 percent of your course grade. Each quiz consists of multiple-choice questions based on your textbook and lab manual reading and problems. Quizzes are open book but time restricted (30 minutes). You may take them multiple times both during and after the quiz period but will be graded only on attempts made by the due date (consult the course Calendar), at which time your last recorded score will become your grade on the quiz.

A quiz link is available within each module of the course Web site. While the quiz is active, you will not be able to ask for help on specific quiz questions; however, after the due date and after you have received your quiz grade, you may address private questions to the mentor.

To prepare for the quiz, be sure to complete the written assignment, laboratory assignments, and readings in your textbook and lab manual and to review all study materials listed in the Study Materials section.

Examinations

You are required to take two (2) proctored online examinations: a midterm exam and a final exam. Both exams require that you use the College's Online Proctor Service (OPS). Please refer to the "Examinations and Proctors" section of the Online Student Handbook (see General Information area of the course Web site) for further information about scheduling and taking online exams and for all exam policies and procedures. You are strongly advised to schedule your exam within the first week of the semester.

Online exams are administered through the course Web site. Consult the course Calendar for the official dates of exam weeks.

Midterm Examination

The midterm exam is a closed-book exam, worth 20 percent of your course grade. It is two hours long and covers all topics and material from Modules 1–5 of the course. The exam consists of multiple-choice questions like those on the module quizzes.

A periodic table, formula bank, list of conversion factors, and tables of common polyatomic ions, common acids and bases, and solubility rules for common ionic compounds in water at 25o will be provided with the exam. But check the "Study Notes" in each module to see which formulas you need to know and which ones will be provided. You may use a scientific (nongraphing) calculator only; programmable calculators are not permitted in examinations.

Final Examination

The final exam is a closed-book exam, worth 20 percent of your course grade. It is two hours long and primarily covers all topics and material from Modules 6–10 of the course, while also drawing on cumulative knowledge gained from earlier modules. The exam consists of multiple-choice questions like those on the module quizzes.

A periodic table, formula bank, list of conversion factors, and tables of common polyatomic ions, common acids and bases, and solubility rules for common ionic compounds in water at 25o will be provided with the exam. But check the "Study Notes" in each module to see which formulas you need to know and which ones will be provided. You may use a scientific (nongraphing) calculator only; programmable calculators are not permitted in examinations.

Statement about Cheating

You are on your honor not to cheat during the exam. Cheating means:

If there is evidence that you have cheated or plagiarized in your exam, the exam will be declared invalid, and you will fail the course.

GRADING AND EVALUATION

Your grade in the course will be determined as follows:

STRATEGIES FOR SUCCESS

First Steps to Success

To succeed in this course, take the following first steps:

Study Tips

Consider the following study tips for success:

ACADEMIC INTEGRITY

Students at Thomas Edison State College are expected to exhibit the highest level of academic citizenship. In particular, students are expected to read and follow all policies, procedures, and program information guidelines contained in publications; pursue their learning goals with honesty and integrity; demonstrate that they are progressing satisfactorily and in a timely fashion by meeting course deadlines and following outlined procedures; observe a code of mutual respect in dealing with mentors, staff, and other students; behave in a manner consistent with the standards and codes of the profession in which they are practicing; keep official records updated regarding changes in name, address, telephone number, or e-mail address; and meet financial obligations in a timely manner. Students not practicing good academic citizenship may be subject to disciplinary action including suspension, dismissal, or financial holds on records.

Academic Dishonesty

Thomas Edison State College expects all of its students to approach their education with academic integrity—the pursuit of scholarly activity free from fraud and deception. All mentors and administrative staff members at the College insist on strict standards of academic honesty in all courses. Academic dishonesty undermines this objective. Academic dishonesty takes the following forms:

Academic dishonesty will result in disciplinary action and possible dismissal from the College. Students who submit papers that are found to be plagiarized will receive an F on the plagiarized assignment, may receive a grade of F for the course, and may face dismissal from the College.

A student who is charged with academic dishonesty will be given oral or written notice of the charge. If a mentor or the College official believes the infraction is serious enough to warrant referral of the case to the academic dean, or if the mentor awards a final grade of F in the course because of the infraction, the student and the mentor will be afforded formal due process.

If a student is found cheating or using unauthorized materials on an examination, he or she will automatically receive a grade of F on that examination. Students who believe they have been falsely accused of academic dishonesty should seek redress through informal discussions with the mentor, through the office of the dean, or through an executive officer of Thomas Edison State College.

Plagiarism

Using someone else’s work as your own is plagiarism. Although it may seem like simple dishonesty, plagiarism is against the law. Thomas Edison State College takes a strong stance against plagiarism, and students found to be plagiarizing will be severely penalized. If you copy phrases, sentences, paragraphs, or whole documents word-for-word—or if you paraphrase by changing a word here and there—without identifying the author, then you are plagiarizing. Please keep in mind that this type of identification applies to Internet sources as well as to print-based sources. Copying and pasting from the Internet, without using quotation marks and without acknowledging sources, constitutes plagiarism. (For information about how to cite Internet sources, see Online Student Handbook > Academic Standards > “Citing Sources.”)

Accidentally copying the words and ideas of another writer does not excuse the charge of plagiarism. It is easy to jot down notes and ideas from many sources and then write your own paper without knowing which words are your own and which are someone else’s. It is more difficult to keep track of each and every source. However, the conscientious writer who wishes to avoid plagiarizing never fails to keep careful track of sources.

Always be aware that if you write without acknowledging the sources of your ideas, you run the risk of being charged with plagiarism.

Clearly, plagiarism, no matter the degree of the intent to deceive, defeats the purpose of education. If you plagiarize deliberately, you are not educating yourself, and you are wasting your time on courses meant to improve your skills. If you plagiarize through carelessness, you are deceiving yourself.
