Untitled DocumentWed Sep 3: Ch1 [13,16,18,29,31]Thu Sep 4: Ch1 [33,36,37,39,40,45,46]Fri Sep 5:Ch1 [54,55, 63, 71,72 ]Several items on the homework for the 3rd included the start up of some "bad habits" which would make the more difficult problems especially difficult. I allowed students to turn in those problems on Monday if they wished. Fridays problems would have the same issues so those would be due on Monday as planned. We ended the 2nd period with some demonstrations of reactions.
Mon Sep 8: Ch1 [75, 77,78,84,86]Let me emphasize that as I grade the homeworks being turned in I see a lot of focus on the answer with out emphasis on the technique used to obtain the answer. These are not worth much. I need clear and well ordered solutions which include units and must be legible and labeled. This is not a math class. Math without any explanation will win you NO credit on exams questions. There are usually 3 parts to consider : 1) number 2) units 3) what you are talking about . For examples: 3 grams Helium or 4.5 moles NaCl or 1.25 M NH3. When student just copy the answer in the back of the book, that is not going to be scored as homework credit. You must show all work used to obtain that solution.Tues Sep 9: Ch1 [88, 89, 94,95,96,106]Wed Sep 10: Ch2 [10, 12 , 13, 41, 42, 47]Thu Sep 11: APPR pretest in class. Today we will waste 1 of the 163 days of instruction on proving that I am instructing properly. Hopefully it won't last the whole period and we can talk about Ch2 problems and topics.Fri Sep 12: Ch2 [51, 54, 57, 60, 63,64]

Mon Sep 22 : Test in Ch3 class Today on items covered to date. Reference tables will include names and periodic table , polyatomic ion and charges.Tues Sep 23 (fall equinox) :Ch3[62,63,65,66] Meet for period 8 in computer lab to work on how to write up and turn in lab work.Today we intended to spend some time on lab write up. Many just finished the test and didn't get a lot of lab time.Wed Sep 24 :Ch3 [68,70,76,77,80,81]Thu Sep 25 :Ch3 [82,83,84,85,86] We were supposed to meet in the computer room but I forgot. Dang. Well we did begin limiting and excess reactants with % yield. Its a very difficult topic for most students and takes practice and organization to get it right.Fri Sep 26 :Ch3 [87,88,89,92] We will work again on homework problems with the following comments:
- There is a strong trend establishing itself. Students either routinely do the homework or routinely do not. This is almost a guarantee of results. You CANNOT expect to get results in a course that builds on itself when you don't have the foundations built well. For the same reason anything fails because of weak foundations, its just not possible. You either keep up or begin to feel like you are not capable. Everyone is capable but there is no short cut through the work
- Student homework is generally 2 pages. You can make it shorter if you don't write everything down but when you do that, you miss the format that helps both you and the grader understand what you are doing. Remember to write things out in order and with detail allows the grader to find the most credit in your answers. This is also true of all tests and will remain true throughout your career.
- Many students are getting lazy about writing out full units. 44.01 g CO2 is not the same thing as just writing 44 and gives almost no clue when you just write 28 because you forgot to add the other oxygen and the grader can't assume that's what you did.
Mon Sep 29 :Fri Sep 26 :Ch3 [93,94,95] SEveral students I know do not have a reputation for sloth. I trust the judgment of these people and attempt to make corrections so that the course runs well for everyone. Some of you have bad habits that need to be addressed. Some need tutoring. Such as after school in the library till about 4. Others just need to keep working diligently and let me know when the homework is over kill. Of course no one wants to think they are doing something wrong. But smart people consider the possibility and adjust if the situation calls for it. I have adjusted homeworks this week to smaller amounts to allow for catch up and completion of this topic I consider fundamental. As you can see I moved the CH3 test as well. Lets get all the lab work together and handle all the fundamentals. Keep giving me advice and things to laugh about. Learning together can be, and should be, fun.Tues Sep 30 :Ch3 [99,100,101]Link to how to set up Text Alerts HEREWed Oct 1: Ch3 [102,103]Thu Oct 2: Ch3 [109,110,112]Fri Oct 3:Ch3 [114,115]We ended the week with the mass percentage of copper in Brass lab. your write up for this lab should first include the calibration of the the spectrometer. describe how you make solutions of a know concentration and measure the specs response to these know concentrations. You then dissolved the brass as if it were copper in nitric acid and added enough water to make it 0.5 moles per liter in concentration if it was all copper. If the mass spec shows a lower percentage, it is because the brass is not only copper. You should show the result and the associated mass percentage of copper.
Mon Oct 6 :Ch3 summary problems samples attached HERE.Tues Oct7 :Chapter 3 test including limiting / excess reactants, balance, ratios, mole amounts. This is a very important and central topic.Several of you performed great on this test. Please make yourselves available to help others who did not do as well. Some of you know what your doing but have to work on labeling and organization to present your solutions. Some of you know parts of the exam but completely bombed others. Make sure you figure out any weak areas. Some of you just did absolutely atrocious. If you are in that category, plan on meeting with me regularly after school on Monday or during advisement / excused period. You really must get the fundamentals down or you will suffer for it all year. When a subject slams you, accept it and push back until you are on top of the problem. Getting slammed can be demoralizing. You feel like working least when you need to work the most. Push back.Wed Oct 8:Ch4 [14,16,23,25,27] Started on Ch 4 lecture stuff today. Covered rules of solubility and molarity.Thu Oct 9:Ch4 [28, 29, 30, 35,37] Will complete the mass percentage of Cu in Brass lab today for those who haven't yet completed.Fri Oct 10:Ch4 [41,43,45,46,47,48]
Columbus day October 13 :Ch4 [51,52,58,60,63] (collected Tuesday) Probably the hardest part of this chapter will be the redox balancing. It is useful for us to know the rules of solubility. They will come in handy with Chapter 15. It is useful to learn a little about acid and base . They will come in handy in Chapter 14 and Redox will be good knowledge in Chapter 17. Introducing these basic now is an ideal time to see how reactions in solution are dealt with. Just as all reactions can be thought of as having a mass for reactant and product, these are no different. However things in solution often express amounts as molarities, NOT masses. Its important for you to know how to use these.Tues Oct14 :Ch4 [65,67,69,74,77,78] KHP titration to standardize a solution concentration.Wed Oct 15:Ch4 [79,80,82,83] Dilution of a standard solution to a known lower concentration ( 0.0500 M)Thu Oct 16:Ch4 [87,88,89,92,96] Standardization of diluted solution with KHP and titration against aspirin.
