  • In PS6.8 there is a typo in the formula of Fe(NO3) it should be Fe(NO3)2 in the chemical equation. Fe(NO3)2 is the iron(II) species referred to in the problem statement.
  • Here is some video from Monday evening's Help Session. Looks like I will not get the second half compressed tonight. I have capture the video twice and each time my computer has crash (*$%@#*). It is after midnight and I'm too tired to try to solve this problem tonight. I'll look at it tomorrow. Do not expect the 2nd half of the Help Session by tomorrow morning....sorry!

    • Sample problem like PS6.9 from the Help Session on Monday, September 25, 2000.

    Here is some help for PS6.7 from the Help Session on Monday, September 25, 2000.

    Sample problem like PS6.2 from the Help Session on Monday, September 25, 2000.

    Here is some help for PS6.1 from the Help Session on Monday, September 25, 2000.

  • PS7 is now available. Fix PS7.6d...

    • it reads HC2H3O2(aq) + HClO4(aq) --->

    it should read HC2H3O2(aq) + KOH(aq) --->

  • If you are using a 56K modem to connect to our Web Site here is a digital lecture from September 18, 2000 which I have compressed for play at that speed. Check it out and let me know what you think.
  • Here are some digital video of portions of lectures from the past week which may be helpful when you are working on PS6.

    Here is some help on formation reactions for PS6.1 from lecture on Friday, September 15, 2000.

    Here is some help on combustion reactions for PS6.1 from lecture on Friday, September 15, 2000.

    Here is some help for PS6.4a from lecture on Friday, September 22, 2000.

    Here is some help for PS6.4b from lecture on Friday, September 22, 2000.

    Sample problem like PS6.5 - PS6.8 from the 1:30 pm lecture on Friday, September 22, 2000.

    Sample problem like PS6.5 - PS6.8 from 3:30 pm lecture on Friday, September 22, 2000.

    Sample problem like PS6.9 from lecture on Friday, September 22, 2000.

  • In PS6.5 disregard the statement at the end of the problem (Use the chemical equation in 5.3) the chemical equation for PS6.5 is given.
  • In PS6.6 the word neutralize means completely reacts with so the problem could be re-worded to say, 'Calculate the volume of 0.360 M NaOH required to completely react with 27.0 mL of 0.820 M HCl? The chemical reaction you should use is;

    • NaOH(aq) + HCl(aq) ---> NaCl(aq) + H2O(l)

  • I've added some sample Real audio files of some sample stoichiometry and sample limiting reagent problems at the Real Audio/Video link. You must have the Real Player (different from the QuickTime Player) to view/listen to these files. Check it out.

  • The exam average 67. FANTASTIC! I was shooting for a 65! The highest exam in each section is a 97. OUTSTANDING! Come to class on Friday and see all the swag the student with the highest grade receives!
  • Kelly Ganzel left his chemistry textbook in the B023 (Chemistry resource Center) around 4:00 pm on Tuesday. Did anyone pick up his book thinking it was their own? Do you now have two books when you thought you only should have one? Contact dr. g.
  • If you are in the 3:30 pm lecture section and have not yet located a laboratory manual you can go to the BookTrader on Hall of Fame, east of Duck on the north side of the road. They were contacted this morning and they still have lab manuals.
  • I've listed the room each section will take their exams this semester at the Exams link. Check it out. If you arrive late to the exam because you get lost and can not find the correct room I am under no oligation to give you the same amount of time to do the exam as those students who arrived on time. (Not that this will be a problem!)
  • Some new stuff to memorize
    •

    Tables 2.3 (p 67), 2.4 (p 69), 2.5 (p 69) and 2.7 (p 73). I'll give you some tricks to make Tables 2.3 and 2.4 real easy to remember, but Table 2.5 and 2.7 have to be memorized. I promise the first exam will have some nomenclature questions.

  • Here is an example of just one of the talents of Robert Sleezer, one of our CHEM 1314 student. If you have a skill that needs to be shared with the world on video, see dr. g.
  • I just had a talk with the Director of the General Chemistry Laboratories and it was agreed that ALL students must wear eye protection in the laboratories. So all students, including HBL, must get eye protection.
  • The tutoring schedule is now available at the Tutoring link. The TA's in red are CHEM 1314 TA's.
  • I've got an initial version of a digital lecture on Wednesday, August 23rd on the QuickTime/Real Lectures link so check it out. Send me an email and let me know what happens or if you have any problems. Welcome to the future!
  • I've listed some recommended problems from Chapters 1 and 2. The list can be found in the Problem Set link at the bottom of the page.
  • If you would like to practice and test your knowledge on significant figures here is some software which will randomly generate questions. There are more of these types of randomly generated questions at our Problem Set link. Just scroll down the page a little to get to the link.
  • In order to post grade information (scores on problem sets, laboratory's and exams) I need your permission. Go the SID#/Name link and enter a number, name or combination unique to you. I will post grade information using your SID# or SIDName. You do not HAVE to have an SID#/Name if you do not want to. There are some additional questions that I would like you to answer for some EXTRA CREDIT.
  • One of the more popular periodic tables on the web is at http://www.shef.ac.uk/~chem/web-elements/. Check out if you need to find some physical properties for any particular elements.
  • Start memorizing..avoid the rush!
  • Things to memorize;

    names and symbols of the first 20 elements and 20 common elements;
    the formula and phase of all of the elements in the periodic table;
    the common prefixes for SI units;
    .

  • Need some extra money? Love computers and like to do Web stuff? Anyone looking for some parttime work writing HTML for a campus project? Check with Dr. G or see Steve Hall in LSE208. You will need to have a resume describing your work/computer experience.
  • I've generated a short Self-Test which has a few questions to provide me with some feedback as to how much you might recall from your past chemistry experience. The Self-Test has six questions. It is not graded, I'd just like to get some information prior to Wednesday's class. Give it a try, see what you can remember. Go to the Self-Test link in the left frame.
