Contact me at

Please put "chem 101" in the subject line of your e-mail to me. I answer student e-mail first and the others go into junk mail, so your messages will go to junk without chem 101 in the subject line! I only ck junk every couple of weeks or so!



**EXAM 2 was on Friday 10/19!! We are waiting for the class average and individual grades on the MC. The Short Answer (SA) will come a bit later .This covered Molecules, Bonding, and Geometry. Expect 14 MC questions worth 77 pts and a multiple part short answer part worth 23 points.

**Check out "frequently asked questions" Check this section out for a number of worksheets with answers for more practice.

**Want to rehear the lectures? See the protected homepage. The total lectures for Bonding and for Geometry are up, along with the last part of Molecules.

**Due Dates- check these carefully as some are due at 11pm to make the assignments show up in the same order as lecture:

**What are my recorded grades??? See your grades on ecampus.

**How do I calculate my MIDTERM grade???
Click here! At midterm, we had 172 points possible (E1 = 100 pts, Hw 1-2 = 20 pts, Assign 1-4= 16 pt, and Pre-course module 36 pts) NOTE: clicker points will not be in Midterm grades, nor will anything be dropped. This is NOT midway of the 716 pts possible in the course. I believe that MidTerm Grades are misleading!!

**How do I calculate my FINAL grade???
Click here for an excel file that will download to your computer. This file is TENTATIVELY correct as of 10/23. Let me check it out during the next week. On Page 2, you can enter your grades for exam 1-4, homework, clickers, assignments and it will tell you what you need on the final. On Page 1, you can enter all grades (the ones you have earned from ecampus and estimate the remaining grades).
Click here! Print this out. Fill in your grades from ecampus leaving the final blank. Add your points up. This is your points without the final. You can subtract the points you have from the lowest number needed for a letter grade to see what you will have to make on the final for that letter grade. As a bonus, you can replace your lowest hourly exam with the % of your final.

**Is there any extra credit?  NO EXTRA CREDIT. (This is the policy for most college-level courses.) Only the credit offered on assignments, clickers, homework, exams is available.

**The ALEKS course is institutional from the assoc chair/director of first year chem. Instructors are only given a percent for the student. I will take the percent, divide by 100, then multiply by 36 to get your number of points out of 36. Your ALEKS percentsAND course points are posted on ecampus.

PAID Individual Tutoring
See me during office hours for ideas about individuals who will tutor for hire in one-to-one sessions.

PAID Group Tutoring
**I don't really recommend any tutoring agency. I think you can pick it up yourself or with the free help available (the SI, the IA, the 406 HELD help desk, the tutor zones, MindTap reviews, my office hours, the sample exams, and reviews movies!). I think the problem with these tutoring agencies is that they teach: 1) methods other than what I do, so students get confused and remember about 1/2 of each so mess up the exams and 2) shortcuts that only work in certain circumstances, so students miss it when I give questions. Use the free tutoring if possible; but if you insist on group tutoring see me, as some a MUCH better than others!

You will have 7 sets of homework assignments, worth 10 pts each. When you miss a problem your online homework will show you how to work it or give you hints about how to work it. Then you will be given a similar, but different problem on your next attempt. You will have 5-10 attempts to get the problems correct.

Only the required assignments MUST be done. The others are for your study. You only need to do the required number of questions (e.g., 2 of 3). No extra credit for doing 3 of 3.

No difference in credit by attempts. You get the same credit if you complete the assignments on the first try or on the last try. No deductions for the number of tries it takes you to get to the required number of questions. Scroll to see all assignments in MindTap when in the weekly view

For 502 AND 506 using MindTap or Young, Vining, et al. MindTap General Chemistry: Atoms First book: Credit is given for the number of assignments (tutor questions and interactive questions) and mastery exercises that are mastered by the due date. Things like the Review, Challenge, and Study Guide are usually for your practice. I recommend these for study AFTER we have finished a chapter.

So if you master all that are assigned, you should receive full credit (10 homework points). The total possible is the addition of the numbers for all graded assignments. For each set, if you did all or at least 95% you will get 10 pts. If you get 90% of them, you will get 9 pts, 80% = 8pts, 70% = 7 pts, 60% = 6 pts, 50% = 5pt, 40% = 4 pts, below 40% = 0 pts.

If you have computer or connection issues, please note that there are computers in the student computing center, which you can use for homework, etc.  You will need your netID and password.

Use this website to login after you are registered in the course: Login from this address, NOT from the ecampus link! Ecampus is down too often!

** See to buy your homework/textbook systen from this website to get the TAMU prices. This deal will ONLY be available from our TAMU link. The publisher offers a 14-day free trial that can be used until you purchase your access code. If you want to take this option, see under To Register below.

**To Purchaseyour textbook bundle go to when you click on chem 101/102, then our section, and purchase, you now have a number of options.

You can purchase the materials for one semester with both electronic and a hardcopy of the book (epack) this should cost you $64, but if you don’t want the hardcopy, then it is $45. These are for 6 months of access. If you are part of the very small group, whose major only requires chem 101, but NOT chem 102, then you want to buy the $64 or $45 6-month version. See below for comments about the hardcopy book.

If you are required to take both chem 101 and 102 for your major, then the cheapest is to buy a 24 month access, where the epack version with the hardcopy of the book is $85 (epack), or you can get the 24 month code without the hard copy of the book for $90 (yes it is higher). In the event that you take chem 102 with a prof who uses OWL instead of MindTap AND you purchased a 24 month code, Cengage will trade codes for free.

You will get immediate access to electronic things and if you purchased a hard copy, the 3-hole punched, color hard copy of the textbook will be shipped to you. The copy of the textbook may be backordered but they will mail it to you when it is ready. The homework system is really embedded in the e-book, such that you read a short section of the book on screen, then have questions right below it….. so unlike some homework systems the etext and the question are in the same screen. Last term, only about 1/2 of my students wanted the print copy (others wanted a print copy available after the code you can decide which one to buy.

If you purchased your materials for more $$ than listed, I would recommend that you take them back for a refund, then purchase them on-line (the bookstore charges $133 for the $85 bundle*?!).

**When ordering your MindTap materials: It won’t matter that the bundle is out of stock, if you are ordering online from l You will get immediate access to the MindTap homework-ebook mix. It is just that Cengage will mail you the hardcopy when it comes into stock, which is usually pretty quickly. You should go ahead and complete the purchase! You will get immediate access to the ebook-homework and the hardcopy will be mailed later. (Quite a number of my students really don't use the hardcopy book.)

**To Register: You can click on register from our class on You will be asked to sign in as a returning student or as a new student. If you just purchased your book using the steps above, use the email and password you set up with Cengage brain as a returning student. If you purchased the book from the bookstore, you will choose new student, set up the account, and enter the access code that will be on a card inside the book. You can also opt to set up a 14-day free trial. You could wait until the Homework help desk opens during the first week. The dates and times it is open will be posted. The TA here can help you through buying and registering your code. Since homework is due on 9/3, you need to get this taken care of soon after school begins if you wait for the helpdesk.


**9/10/18- reports of graphics not displaying in 3.2a. Try to switch to another browser. Firefox, Safari, Chrome, etc. A number of those reporting issues were using Chrome. Firefox or Safari may be better options.

**If you have trouble with the buttons not appearing on the screen for a homework assingment, try another browser like FIREFOX. Chrome seems to have an issue with this.

**9/12/ 18 THERE IS AN ERROR IN THE CONVERSION TABLE ON 1.4A. 1 cm is NOT equal to 2.54 inches!! 1 inch = 2.54 cm. This has been turned into Cengage to be fixed!!

**THERE ARE SOME REPORTS OF 4.1 MASTERY and 4.4 Mastery SHOWING UP as not submitted or as review only, but it has the correct score. This is usually fixed when the due date/time go by.

**On 4.2 Mastery, you must choose a number for the last 2 quantum numbers. So for 3p, say the QN would be 3,1,1,+1/2, which would be just as correct as 3,1,0,-1/2--don't say that the spin number is +1/2, -1/2 choose one!!

**Students cannot use calculators that are programmable or have alpha-numeric capabilities for the exams. This means no TI-eighty anything. You CAN NOT use a TI-83 since it has alphabetic memory. You need a TI 30 or 36 or its Casio equilivent. The calculator cannot have alphabetic memory. It should cost $9-15. Be sure to buy one with the keystrokes you like. For example: TI-83 requires that you put in log then the number. If you want this same keystroke for your lower calculator, then at the store, hit the log button. If the calculator gives you an error, this calculator will require that you put in the number, then hit log. If the calculator says log and is ready for the number, this calculator has the same keystrokes as your TI-8X.

There are 10 points in the syllabus for the essay assignment. 

Want a copy of the yellow sheet that was passed out in class on 10/30 that describes how to logon to Click here for a pdf of the sheet.

From the handout:
Once your essay is uploaded and processed, any part of your text in color can be considered by me to be plagiarized. We know that your references, a common set of words or a common list will be colored or flagged. These do not matter or count as plagiariam.
  Since this is a causal paper, you really shouldn't use quotes. As listed on the bottom of your handout sheet.

-1 or -2 for low word count
-1 for copied sentence or not citing a quote (multiple sentences = multiple deductions)
-1 for each of the 3 references you were missing (remember 1 had to be a written source)
-4 or -8 for problems with originality that were not references, technical terms, or quotes.

** If you think there was an error in grading your exam after you compare the score you get with grading duing the key and the grade posted on ecampus. go to 412 HELD, fill out a regrade form, and turn it in. They will make a copy of your scan, hand grade it, and tell you when you can pick up the form and copy.

**If you want to see your exams, come in during office hours (IA's or mine). You may only visit your exam until the next exam. You can rework the problems, but NOT copy the questions down.

**If you missed an exam and need to sign up for the makeup exam, see or e-mail me. Makeups are granted for university reasons (or VERY good ones). Otherwise, the missed exam is the one you will replace with the final percentage.

**If you didn't like your exam 1 score, remember that your final percentage can replace your lowest hourly exam, but you don't want a second low exam, so: (1) Download the grade calculator in the grades section below. and (2) Review your exam during any office hour before exam 2 to decide on a personal strategy for improvement. Also remember that your clicker, homework, and assignments pts should be 135 pts (15 + 70 +20) on which you should have at or near 100% on. IF you are doing these, you can make a little lower on exams than the letter grade you want in the course.


Exam I = Class Average =68.9 /100 pts for the total exam for both classes.

**Why is the exam average important??? There is no extra credit. I don't curve, but will lower the points required for each grade at the end of the semester, based to a large part on the averages on the exams. Use the average to let you know both how you are doing compared to the class and how the class is doing. also remember that your exam grades can be a little lower than you want for the course, since your quizzes (36 pts) and homework (70 pts) are more than a test grade, for which you should get close to 100, in addition to the 1 exam grade that you can drop.

**I do not return exams. You can review your exam and rework the problems on your exam. You cannot copy the questions word-for-word but may take notes on the concepts that you missed. You can do this anytime during my office hours or during your IA'soffice hours. You can only review exam 1 until we have exam 2, and so forth. You will receive any short answer part back once it is graded.

**To study for the exam, do: 
1) your homework (at least some of each required section),
2) the two sample exams,
3) go over your objective sheet,
4) practice any objectives that you are weak on by doing more problems on that topic (on OWL click on 'past due assignments' to do any OLD OWL assignments for review)
5) Do a quick read of the sections that are stated on your objective sheet.
6) Finally, go over the sample exams again, this time read the question and say HOW to work the problem, then uncover your answer and see if you know how to work the problem by reading it.
7) Then get a good night's sleep!!

The university approved non-REEF iclicker2 is ISBN- 9781429280471. It costs 56.00 new or $45.90 used, plus tax for the device. Both have no cost to register your clicker into a course. We won’t use the reef polling, but you might need the new for other classes. BUT the one with reef polling will do the plain polling we will do. Once you buy the clicker, you can use it for all your courses that require i>clickers for the remainder of your time at Texas A&M. You can also resell it. There are options to rent, but if you would have to rent both semesters for chem 101 and 102, it is cheaper to buy then resell later. Two students can share a clicker as long as they are not in the same class (students in one of my sections can’t share with a student in another of my sections). You can purchase your iclicker2 at the Texas A&M Bookstore and other bookstores, We will use the iclicker everyday, BUT it will be the second week or so until we begin counting it for a grade!

Register your iclickers at This is also linked on ecampus. WHEN YOU REGISTER YOUR CLICKERS, USE YOUR TAMU UIN, no dashes or spaces! We will use iclicker classic, and TAMU uses blackboard for its learning management system.

Your clicker grades are 1 pt for each correct answer up to 3 questions + 1 for responding, which you will receive if ALL questions are wrong. This means that if there is 1 question during the lecture, it will be a 2 pt day. If there are 3 questions, it will be a 4 pt day. If there are 4 questions, it will be a 4 pt day because I will take your best 3 questions +1. Clicker pts do NOT equal course points. If you get 70% of the clicker pts, then you will get all 15 course pts, if you get 65 to 69% then you get 14, etc. as spelled out in the syllabus. The threshold is low to allow for bad batteries, university absences,dentist appts, etc. and since I have just lectured on a topic, I would expect a low C. Therefore a low C or 70% is all you need for full course credit.

**Chem 101 is the lecture course.  Chem 111 is the lab course.  These are separate courses. Chem 111 will be taught by a Teaching Assistant (a TA).  Dr. Lee and Dr. Bethel are the lab coordinators, in charge of curriculum and grades.  The instructor listed on Howdy, is only the lab apparel safety inspector! If you have questions about the lab course contact Dr. Lee at or Dr. Bethel at rbethel@chem.tamu.ed (not the safety inspector).

**Your score on the diagnostic Math test given on 8/29 is posted on ecampus. This is NOT part of your grade. What this tells you is that if you made less than 8 out of the 20 possible, you should take care with mathematical concepts. This means get help quickly if you are not understanding. Get help in office hours of mine or Ryan's, in SI, from the TA's in HELD 406 (but away from times the labs begin), in the free Tutor zones (see times/places on the homepage), study groups, or as last resort hire an individual tutor (I do have some names). You retook this Math test after a review. Those scores will also be posted when they are completed. We don't know for sure, but it seems like quite a number of students really improved with the second administration. Hopefully these will be ready to be posted within a week.**Be sure to download the excel grade calculator in the 'grades' section, so you can estimate your grade throughout the semester.
