REQUIRED MATERIALS

Text: Chemistry: The Molecular Nature of Matter and Change, 8th Ed., by Martin S. Silberberg*.

Lecture notes: Available only at the NYU Bookstore (do not mistakenly purchase the CHEM-UA 125 notes!).

iClicker lecture response device: available at the NYU Bookstore.

Scientific calculator: Your calculator must be capable of evaluating logarithms, performing exponentiation, and calculating trigonometric functions. It must have at least an eight-digit display and you must be able to switch between scientific notation and decimal notation. Most standard scientific calculators have these features and they are priced as low as $13. If you use an advanced scientific calculator, you must delete all programs and/or text related to chemistry before an exam or quiz.

*Your Chemistry course is participating in the IncludED program. This is an NYU Bookstore initiative that delivers required course materials digitally at the lowest possible price. The book, Chemisty by Silberberg, will be delivered to you digitally. You will receive an email the week before classes giving you the link to access the material. The cost of the book is $94.50, which will be added as a "book charge" to your bursar bill, this is a savings of $175.00 over the new hardcopy price. If you decide not to use this digital edition you can opt-out of the program. The deadline for opting out is June 3rd. You can find the opt-out link and more information about the program here:

LECTURES

Every topic that you need to know for this course will be either covered in lecture or specified in lecture as a reading assignment. There are topics in the book that we will skip or cover lightly. There are other cases where the book devotes little or no coverage to a topic and we will look at it in detail. To learn what is important, and what it is about it that I consider important, you need to attend the lectures. The course is the lectures. The book is a tool.

While attending lecture is important, it is not where you actually gain an understanding of chemistry. You have to take all of the information presented to you and fit it together. You have to build your own model of the (chemical) world that is consistent with everyone else's model (especially mine). That takes a lot of thought, effort, and practice. The amount of time necessary will vary from person to person. However, at a bare minimum, plan on spending at least twice as much time working outside of class as the amount spent in class. For the summer, that is a large fraction of your time. If you want to understand chemistry (and/or get a good grade), that is what it will take. I had a line in the first term syllabus that said you'd need to "eat, breathe, and sleep chemistry". As those of you from the first summer term now know, I wasn't joking.

We will generally follow the sequence of topics from the book. However, whenever the notes differ from the book, follow the notes. They may only differ in emphasis, or they may actually disagree with statements from the text. I'll usually mention when any difference arises. One chapter in which we will differ from the book is Chapter 17. I will even hand out a set of homework problems not from the book for that particular chapter.

To ensure that you have a correct version of the notes and to allow you to listen to the lectures rather than simply transcribe them, you should purchase reduced size copies of the lecture slides. These "Lecture Notes" are sold at the NYU Bookstore. Within the notes, there are some items that you'll have to fill in (generally, numerical examples) and I recommend that you use the wide margins to mark down other things that I say or to show the emphasis that I place on a particular section. I will not be putting the notes on our web page. This is not a distance learning course.

Attendance of the lectures is required and will be monitored through the iClickers. After you miss three (3) lectures, I will begin to deduct 1/2 point from your overall score for each additional absence. If you don't check in or answer a question with your device during a lecture, then you were not there (forgotten devices, arriving too late, dead batteries, etc., count as absences).

Some people like chemistry and some people don't. Most people like General Chemistry II more than General Chemistry I. I think this common preference for the second course is because the connections between various topics are easier to see (even when they appear in different chapters), you learn the truth about some points that were "oversimplified" in the first course, and you are able to generalize what you learn more effectively. By "generalize", I mean that by studying subjects like chemical equilibrium, you'll find it easier to understand some non-chemical things (if there are such things) in the world, such as traffic, the economy, life and death ... pretty important stuff.



RECITATIONS

The recitation is intended to help you to understand the course material. While it is also where you are quizzed and where you hand in your homework, you should view its primary purpose as a question and answer session where you can obtain an explanation of any course material.

Your homework will not be "corrected". You will hand it in and it will be evaluated for completeness and authenticity (i.e., is it "real", or is it just a copy of the solutions manual?). If you make a mistake, it is up to you to find that out and to find out just where you went wrong. Usually, you'll know when you're likely to have made a mistake and you can ask for help during recitation. Work with other students outside of class. Go to your instructor's office hours and ask there. It is regrettable, but the instructors do not have time to examine each homework set for errors.

Numerical answers to the homework problems will be available on the course web page (see below) shortly before the due date. You can check many of your answers before going to recitation so that if you have gotten a particular problem wrong, you'll know that you need help with it. Detailed solution methods will not be given because I believe that these would inhibit your thinking the problem through. Answers to conceptual questions will not be available on-line because, again, they would inhibit your thinking about the problem. It is a bad idea to look at complete solutions (if you should find them) because you'll learn a lot more if you figure the answers out for yourself.

The quiz will be given at the end of each recitation meeting. It will consist of a couple of problems or questions dealing with material covered in the lectures. You will always have more than 24 hours between lecture coverage and the quiz on a particular topic. However, since homework is not due until after a chapter has been collected, yet the quiz is meant to keep you current, you can be quizzed on a topic for which the homework has not been turned in. Stay up to date on topics, and you'll stay up to date for the quiz. In order to ensure equality between recitation sections, you MUST hand in your quiz when the instructor says that the time allowed has elapsed. 10 minutes is scheduled for each quiz.



HOMEWORK ASSIGNMENTS

The assigned problems have been chosen to clarify concepts that I regard as important and to give you practice in solving problems of the type commonly encountered on quizzes and exams. It is NOT possible to perform well at test time unless you have done the homework. One of the most frequent remarks I hear (after an exam) is "I really understand the material. I just can't solve the problems!" What would you do if your doctor said "I understand your illness completely. I'm just not very good at curing it!"? I'll be happy if you do understand the material. But the fact is, your grade is going to depend upon your demonstrating that you understand it. To prove it, you have to answer questions and solve problems. Responding correctly, quickly, and coherently to these problems will require practice. So ... "do" the problems. In addition to the 9 % of your grade that they earn, you will perform better at test time.

Some recommendations:



WEB COMPONENTS

There is a web page for all general chemistry courses at NYU. The URL is

http://www.nyu.edu/classes/inorg

The General Chemistry II page will contain information about this course and will be used to disseminate supplementary materials and to make announcements concerning the course. It contains a number of items and I recommend that you look at it to see what is available at your earliest opportunity. Please pay particular attention to the "Announcements" section. There you will find all important administrative notices for the course.

I will set up an NYUClasses page for the lecture section and, if your instructor requests, for your recitation section. The lecture NYUClasses page will be used by Prof. An for the laboratory portion of the course - I will be using the NYUClasses page merely to send email messages to the entire class.

A note about email: Like last semester, do not send email to me. See me in person whenever you have a question or need something from me. I have 2 hours set aside to meet with you each week and I am willing to talk with individuals at the end of each lecture. I will not reply to any email sent to me (so you will be wasting your time by sending it).





GRADING

There will be three examinations during this course. They will be held on alternate Thursdays (7/18, 8/1, and 8/15) from 9:15 a.m. to 10:55 a.m. They are not explicitly cumulative, though new chemical topics tend to build upon past topics. There will be a quiz during every recitation meeting. You must complete the homework and turn it in on the due dates. Your grade will be evaluated as
lab25%
exams18% each
quizzes12%
homework9%




STUDENTS WITH DISABILITIES

If you have a documented disability you can arrange to take quizzes and or exams at the Center for Students with Disabilities (726 Broadway, 2nd Floor). It is your responsibility to make arrangements with that office and with me before the first quiz or exam.



ILLNESS

If you miss a lecture due to illness, study the lecture notes and feel free to ask questions about them. If you miss a quiz, you must provide documentation on a physician's stationery that says that you were too ill to attend the recitation. If you are ill on the day of an exam and can provide a doctor's note, your grade will be calculated based upon the other exams and coursework. Lecture/recitation/exam documentation must be given directly to Prof. Halpin; laboratory documentation must be given to Prof. An. All documentation MUST include your name and dates to which it applies. YOU MUST attach to that a "documentation cover sheet" (downloadable in PDF format from our course web page) that shows exactly what work you missed (e.g., lecture, quiz, exam) and the section number of your recitation (if that cover sheet is missing, the documentation will not be used and the absence will go unexcused). Prof. An will provide her own documentation cover sheet for the laboratory portion of this course. ALL documentation is subject to verification. An excused quiz will not count, but you still have to complete the homework. Unexcused quizzes count as zeros. If you miss more than one of the three exams and you have a doctor's note, I will give you an incomplete (I) for the course and you can take a make-up exam during the fall 2019 semester. Any absence will put you behind in your work. At the pace of the course, it will be difficult to catch up. My advice is to avoid getting sick.



CONDUCT

Cheating in any form will result in a failing grade for this course and it will be noted in your university records. It will ruin your career. If you give information to another student during a quiz or an exam, you are both cheating. We are very good at detecting cheating. Don't try it.
