I'm not sure if the links are supposed to the be the same or not but the midterm link seems to be the same as the old midterm questions we had gone over in class.
Question 25 of the Fall Midterm. We have learned about boiling points in class, but not melting points. Phenol as the highest melting point makes sense due to hydrogen bonding. I would put toluene 2nd and benzene 3rd as the shapes are the same, with an added CH3 group adding extra molecular weight to toluene. Does a compounds melting point have additional factors, and do we need to know how to determine melting points if so?
Why is CF2Cl2 always polar when it perhaps could my wrong thought be symmetrical with the flourines on one axis and the chlorines on the other? Which one is correct? This exact example is straight out of the later notes, though. The b. Resonance structures seem ambigious.
If we can draw a single dominant structure then do we assume theres only 1 structure? Does so3 have 1 resonance structure or 4? What wiuld we put on a test. I was was wondering if we would be able to have scrap paper for the midterm, because the papers are double sided with small margins.
SO3 has even more than 4, actually, since by expanding the octet you can have 1, 2 or 3 double bonds. Use the back of the data sheet. For question 14 on the midterm, Would the best LS for SO3 be: S with each O connected to S by double bonds because this would make the formal charge O for each of the atoms and S can expand its octet because it's in the 3rd row of the periodic table?
Wouldn't this mean that there isn't resonance because this is the best LS? I'm just a bit confused by this. Are there going to be questions on enthalpy or lattice energy, since these were covered in Midterm 1? On the upcoming midterm, could we ask for blank papers from the invigilator? It would be a lot easier if we can draw lewis structures on a separate piece of paper rather than on the sides of our testpaper.
The 3 Lewis structures with just one double bond are good in that they obey the octet rule, but are not so good in that formal charge is high. In such cases, it is difficult to know which is best, so it's safest to assume that they're all contributing to the overall bonding picture.
Note that the other four options don't allow you to draw any other Lewis structures, so you can eliminate them from consideration.
Professor McIndoe, this might not be the right place to ask this, but is it all right if I come in during your office hours and ask you some questions not pertaining to the Chem course material? Specifically, the questions have to do with spectrophotometry. Are you the right person to ask, or should I find someone else to help me? I'd avoid visiting my office hours this week with that question everyone else there will have questions about the midtermbut in general, sure.
My research expertise does not lie in spectrophotometry, but once I find out a bit more I can at least point you in the right direction. Question 2 of the Midterm I understand why C isn't a valid resonance structure. There should only be one double bond with N and an O. It has 26 valence electrons, which means it would have a lone pair on Cl.Header search input. Study Resources.

CHEM 102 Midterm: exam 1 review
This subject matter builds on the chemical principles encountered in CHMwhich, in turn, were found to underpin and describe, on a microscopic scale, the world around us.
Relevant material from the following chapters of Chemistry: A Molecular Approach will be discussed during lectures see misc. Independent study assignments will not be collected for grading. Copies of the solution manual are available in the library reserve room, or a copy may be viewed in my office E See the final section of this document for some additional important details regarding HWK assignments. Since CHM is a continuation of CHMstudents are assumed to possess a solid background in and an appropriate mastery of subject matter previously covered in CHM The laboratory sequence has also been designed so that students encounter a variety of chemically significant processes and so, in turn, develop an understanding of the fundamental chemical principles that describe them.
Thus, the lab assignments of chemistry often provide illustrative examples of the principles covered in class. All experimental procedures, and well as their respective pre and post-lab assignments, may be found within the Chemistry lab manual or downloadable files.
Lab sessions will take place during the last class period of the week, unless otherwise specified. A written description of what is required to successfully complete each lab write up will be distributed during the first lab session.College Algebra Introduction Review - Basic Overview, Study Guide, Examples & Practice Problems
These values will be used, in conjunction with quiz and exam scores, to calculate final course grades see below. Students will complete laboratory assignments in groups possessing either two or occasionally four members.
Students must wear approved safety goggles, be appropriately dressed, and adhere with all safety regulations at all times when in the laboratory. Safety rules and regulations will be reviewed during the first lab session. Any student who is pregnant or may become pregnant during the course of the semester is strongly advised to consult their doctor before enrolling in this course.
Students must make up any and each missed lab assignment within one week of their absence s from the laboratory. Lab make ups may NOT be completed during the last week of class or Finals week.
Students that do not make up missed laboratory assignment s will receive a score of zero for that assignment s. Any student who misses more than 3 laboratory periods and does not make them up will have a full letter grade deducted from their final course grade. If you miss a lab be sure to see Dr.
Mills as soon as possible for details on times and dates for making up the missed work. On time lab check-in first week and check-outs last week count towards lab attendance and points totals. The final course grade is based on a preliminary quiz 15 points3 midterm quizzes 25 points each2 midterm exams points each and a comprehensive ACS standardized final exam points featuring material from both CHM and CHM A maximum of points will also be awarded for laboratory work.
A maximum score, before extra credit, of points may be earned during the course. The final course grades will be based on a normal or "curved" statistical distribution of the cumulative scores for all graded work i.Everything went very smoothly and we highly recommend to friends and family that you are the place to go for their Nordic Travel. Thank you so much. I have already been telling everyone what a great experience we had and sending people your way.
We couldn't have had one of our best and most memorable holidays without you. It was just stressfree and fabulous. We are United Staters, we have been all over country including to Alaska back country twice and we have been to Ireland, England, Wales, ItalyFrance and Greece.
I have enjoyed any of them as much as enjoyed Iceland. The whole process from start to finish was very clear, Petra was very helpful and we would happily book another tour with you. Everything went very well on our tour. There were no issues with bookings and the hotels used were well located and good. We had a wonderful time in Norway thanks to Sara and your company. The service provided by Sara made it a very straight forward holiday. The tour provided us with an excellent overview of Norway and we departed with very happy memories.
I really like that I have an assigned agent for my trip booked with Nordic Visitor. As our plane arrived late at Copenhagen airport, I didn't see the limousine drive holding a sign with my name and got worried.

I sent an email to my agent, and was informed right away that she had called the limousine service and told me the exact location the drive was waiting. I found the driver and started to relax and enjoy my first trip to Scandinavia. The upgrade to the first class train ride from Stockholm to Copenhagen really enhanced the journey. The detailed itineraries reminded us things to do and suggested attractions to visit.
The overall experience with Nordic Visitor is simply awesome. Everything about our trip was perfect. Our guesthouses were exceptional. Maria went above and beyond for us. Thank you so much. Overall the trip was terrific and Hanna specially was exceptional. Everything that was provided was very detailed and top notch.
She was also very patient with all our questions and changes that we requested. I would highly recommend Nordic Visitor and Hanna would be our go to person on any future trips.
I have already recommended Nordic Visitor to all my friends, family and colleagues. Our flight departure was delayed an entire day and we were concerned about losing out on our first day activity, airport transportation and accommodation.Remember you can try to beat Lawro by playing the BBC Sport Predictor game. Last week, Lawro got four correct results, including one perfect scores, from 10 matches, for a total of 70 points.
He beat England cricket captain Joe Root, who got five results correct but with no perfect scores, for a total of 50 points.
