Info for final class:
Class Video 5/2 (includes most of gas laws [chapter 12]
Video from 4/25 class (to rewatch about stomach processes, catalysts, equilbrium, acids, etc
Test Wednesday, on what we've covered in chapters 10 and 12 and related topics in class.
Homework to have done
Ch 12 RQ: 1-8
Ch 12 PP: 1-3, 7-9
Chapter 10 odd questions from RQ and PP. (from last week)
Read pages 404-408 and do the OYO question. (from last week)
Key topics included on the test include (but are not limited to):
Knowing what makes something acidic\basic (both by the properties of a substance and chemically).
Being able to name acids\bases\salts in reactions
The general neutralization reaction acids\bases produce
Be able to name a few acids and bases
Polyprotic, amphoteric
Stuff from the 4/25 video (including how the stomach dissolves things, what an enzyme\catalyst is, amino acids\proteins, equilibria, why sulfuric acid is so much more dangerous, and others)
Boyle's Law, Charles' Law, and applicable situations (are tires larger at warm or cold temps? if you went up on a mountain would a balloon expand or shrink (remember there's less pressure as you rise in the atmosphere because there's less air above you), etc
Ideal Gas Law, what are the assumptions, and what conditions help conditions be similar to the assumptions
Briefly, Dalton's Law of Partial Pressures
MAKE SURE TEMPERATURES ARE IN KELVIN IN THE CH 12 QUESTIONS!
What is pressure, what are some units it is measured in, and what is standard atmospheric pressure
How pressure is shown on a diagram of molecules
What is temperature really a measure of?
I will take extra credit work\test through Friday to give you time to study for this, it should be a good chance to get some helpful points :)
Finish Strong!
Update 5/1:
Late putting up hw, I recognize. That said, good to do it tonight if you were putting off doing hw until now anyways, as it'll refresh and leave you with less homework later. But not required to have tomorrow...
Suggest reading 383-393 for review\introduction to a couple smaller concepts we'll cover quickly tomorrow.
Update 4/19:
I need you to check to make sure you have your book and only your book, as mine is missing.
Because of that we will just make the homework straightforward and simplified... read all of chapter 10, doing the on your own questions as you go. I would suggest taking notes, too. I will expect you'll have a healthy idea of the main ideas by the time you come to class next week so we can pick right up. If I my book can be found. It should say TE on the top.
Video of 4/11 class
Update 4/17:
As noted in class and on this site last week, we have a test Wednesday and homework is the Solubility practice sheet (below on 4/9) that no one turned in, as well as all PP and RQ from Ch 11. 4 weeks to go. Finish strong.
Update 4/9:
I am still waiting for Anthony to turn in Solubility Practice 1. I will probably post solutions Tuesday regardless.
Here is the hw for next class. Since I didn't put it up until today, I will take it next week BUT I still suggest you put in the effort and do it now. It will benefit you.
Homework for this next week will be chapter 11 RQ and PP.
Last part of 3/28 class
Extra credit option:
I will allow the option to replace your lowest test grade and lowest homework grade by work on chapter 13 before the end of the semester. What you will have to do: read chapter 13, do the OYO, RQ, and PP, and take the test. The test will be a standard test for the chapter. Your lowest test grade will be replaced with your grade on this test (if it is higher) and your HW grade will be replaced by your HW grades on Ch 13. if you are wanting honors credit, you will likely have to do this chapter as well as an additional small assignment to be given in April.
Also, just for your benefit, and to show how much you do\do not know, I wanted to show you some practice from an AP Chemistry (college credit in high school) course. A taste of the level you'll be held to in college. Keep working hard, and I believe you can accomplish a lot :).
Homework due 3/28:
1 - Do the summary lab reports on our two experiments (since they are in the video, I want them from all 4 people in the class please)
2 - Do the solubility practice worksheet (available here). The second example is filled in at the given link. DO the last practice and the actual questions, get in touch if you start having struggle. The video has good hints.
3/21 class video: part 1 part 2
Homework due 3/21:
Read pages 334-335 (yes it's in chapter 10, not the chapter we are studying, but covers an idea I want to focus on, concentration. Don't worry so much about the acid and base mentions, they're just examples) and 364-375. Write some notes on the key terms\topics to bring to class to prove you did the homework, and for help studying for your test in a couple weeks.
Information about 3/14 class:
Generally plan on having the test this Wednesday on Chapter 9 and the topics we talked about in class that relate to it.
Video of 3/7 class (for Ethan)
For homework, do the practice problems and review questions at the end of chapter 9. They should be a fairly solid practice for the test from what I've seen. If you email ([email protected]) me your general answers by Tuesday night at 8 PM, I will send you a link to my answers, great review.
The only other main topic will be about how the polar nature affects water from 3/7's class (which you can always watch to review!).
Anthony you did not come to retake the quiz Friday... and I checked the video... I talk extensively about the fact there'd be a quiz the next week at about 16:00 and 18:30 into the video. Since you were given a second chance to retake it and did not follow it up, your 0 will have to stand on that. Make it up by working hard for the test.
Ethan you do not have to take the Ch 9 test this week if you do not feel ready, but will definitely want to work towards the topics. You'll have to stay on top of it, so often a student will get a delay on a test, and only use it as a chance to slack. Dominate!
Everyone please let me know how the studying and learning this material is going. I want to know if you have problems with the homework, it may guide my planning. But you must tell me early.
here is the video from 2/29 class
Class Recording 2\22
Due 2/22 -
1: Do this practice sheet. When done, immediately email ([email protected]) your general answers or send as a picture message so I can give you the link to the answers. The earlier people send me these, the more extra credit is reasonable on the test, because it shows you aren't waiting until the last minute.
2: Do odd RQ and PP from Ch 8.
Answers to first worksheet from Ch 8.
Due 2/15 - Read pages 272-278. Finish lab report. Do practice problems sheet that is now available here.
Due 2/8 - Review Questions (pg 245) and Practice Problems for Chapter 7 from the book. If you want to check if some of your answers are right, feel free to send them early and I can tell you how you did. Test Wednesday on Ch 7. Lab is due 2/15, here is your link for the spectra for different elements (you will need Java). Don't forget, we want EMISSION spectra... and the answers aren't perfect, but you will have to do your best. All are natural elements.
Answers to Light HW from a while back: Page 1 Page 2
Due 2/1 - Do Practice Sheet and keep studying. Make sure you know your models, and if you aren't getting quantum dynamic electron configuration, read the end of chapter 7 in the book about it. Otherwise, not a whole lot. MAKE SURE YOU HAVE BOTH THE HW DUE THIS WEEK AND THE ONE DUE LAST WEEK ON WED.
Due 1/25 - Read pages 219-224 (and come ready to ask questions). Then do this practice sheet using the light equations (and with a few review). BTW, you guys were right about Neptune, I'm surprised to learn that is significantly water. So many of the shows that talk about water in the solar system only emphasize Europa. Good to know, thanks!
Due 1/18 - Read page 208. Then read this about the history of the nuclear bomb and then write a paragraph summary. Finally, do these review questions.
Lab 1
Lab 2
Lab 3
Lab 4
Lab 5
Lab 6
Extra credit\honors lab due by Tuesday afternoon
Due 12/14 - RQ Ch 6: 1-9 odd, PP Ch 6: 1-9 odd... if you complete a question and want to know if the answer, send me your work, and I can let you know how it is.
If you are interested in any kind of food\small fun after the lab, let me know during this week and we can try to work something good out :)
If interested in a study meetup, I might be able to for a few hours Monday. But you need to bug me this weekend to show me you really are interested it, and motivate me to finalize it.
Here are the answers to last week's homework (questions 1-3).
Approximate test breakdown: 45% full stoichiometry questions (probably 4 or 5 questions)... 20% definitions\terms\key values you've memorized (Avogadro's #!), and a few review question (that was the method of reviewing old material instead of a cumulative, check your syllabus)... 20% writing reactions and balancing... 15% molecular\empirical questions, and perhaps a few small point questions on finding molar mass.
Old Stuff:
Due 12/7: Stoichiometry practice problems here. This will be your last significant homework of the semester, you'll probably have a few chapter review next week. Also, please work on organizing together your lab notebook [separate from your class notebook] (which right now should be pretty empty... since you've gotten only lab 1 back.. but you'll hopefully will get more Wed). Here is a refresher\help\checklist on stoichiometry, with a practice problem.
Due 11/30: Completely solve the problem below carefully:
If I start the formation reaction of carbon-monophosphorus-monochloride with 260 g of carbon, 310 g of phosphorus, and 214 g of chlorine, what will I end up with?
Due 11/16: Lab Writeup on the class demonstration. Nothing too fancy, but keep it in lab format. Additional work:
1 - We used ethyl alcohol, C2H4OH (= C2H5O). Determine the balanced complete combustion reaction.
2 - Determine the mass of 1 mole of ethyl alcohol.
3 - The density of ethyl alcohol is 0.789 g/cm^3. Determine the mass of ethyl alcohol we used.
4 - How many moles would this be?
Questions to answer:
1. Attempt to explain how the reaction physically evolved in terms of what you heard and saw based upon the chemical reaction and available reactants.
2. Research ethanol as a fuel and write a summary paragraph. Make sure to include the energy density values and benefits and shortcomings. Wikipedia is a valid starting point, but you must give source for your actual information with non-collection (non-wikipedia) website(s).
Due 11/9: 7 practice problems with writing and balancing reactions, available here
Due 11/2: Chapter Review and Practice Problem sets at the end of Chapters 3 and 4 (40 problems total)
Due 10/26: Lab and memorize 10 more elements... gold, silver, platinum, uranium, copper, mercury, lead, zinc, tin, iron.
New for off week: Ok, I'll just add one thing to the lab and poster... memorize elements 1-20 on the periodic table. This includes the name, atomic symbol (the 1-2 letter abbreviation for each element), and the atomic number (the integer above the name). Also, you need to know the three properties that differentiate a metal from a nonmetal (I'm not sure if we covered this in class or not... it's on page 77, paragraph 2). I suggest earnestly that you read pages 74-83 to remind yourself a lot of what we talked about in class. Hope you had a good week off :-)
Update 9/29: Ok, indeed a big mistake on my part... next week we do have class, it is the following week we will miss. Yes you have to come next week, be happy you have one day off! To match that better the schedule, here is how I'll change homework
1 - Reduce book hw: do all RQ, but only Practice Problems 2-10 even. Do it before the test.
2 - Lab is due in 2 weeks (even though we don't have class, I'll see most of you... turning it earlier is ok if you wish, but make sure all else is done first)
3 - A couple more thoughts on attitude
4 - On Your Own from chapter 2 is great practice and has the answers at the end of the chapter.
A review of a calorimetry problem where you have to solve for Tf (the more complex ones from class)
5 - Take home test due next Wednesday. I decided that what I'm looking for is basically closed book. Perhaps allow yourself one break in the middle to remind yourself a couple ideas if it's not going well, look up a term or two... but don't use the notes to do the questions as you go, don't copy. That's not learning anything, not showing you understand. I'm doing this on the honors system, but I think I should be able to tell if people are using their notes\books too much. In return, I will not make the test harder than usual (typically take home tests are much harder than a regular test, since you would have notes to use). Take home test now online here.
If anyone needs another format or a printed copy, I do not mind, let me know. Get it from me soon. Do not wait until the last minute, as it'll be too late for excuses.
Update 9/25: If you have not heard, the test has been postponed until a week from this Wednesdsay. The homework is due this Wednesday instead of earlier. Hope that helps. Wed we will probably retry the lab, and we will cover chapter 3 material. The hw due this week is HERE. It is very important that you do it.
HW for the week between 9/7 and 9/14
1: Temperature Conversion Practice Sheet
2: Found the video! Watch the full 2 hour video on cooling. I just did :-) The first half is about the early history of the understanding of cold, the second half is the newer quest to reach absolute zero. When done, write 5 facts\interesting things that stuck with you from the video
If you need an account for the weird activation, login as username [email protected], password elements1 and it will let you watch
Old HW
Practice Problems for Week 1: Here
Here is the practice set for given 8/31.
Will take them up until Midnight Monday night (9/5/11). Answer key will be sent out afterwards.
My video covering complex unit conversions... information about the density of water... and unit standards is done, but goodness, difficult to get uploaded in a reasonable way
I think YouTube is now coming along. The split AVI files should start showing up on my channel very shortly. You can also try using the Flash version directly on this site here, but it has awfully limited controls. And if it doesn't automatically load the next video, change the filename in the address bar to Chem1_2011_1.swf, Chem1_2011_2.swf and so on...). If neither work, you'll have to download the absurdly large AVI file. It is here... but may not be done uploading still til like 3:00... and it's like an hour download. Oye, movies continue to be my bane. Yipe.
Yes the video is about an hour long. Worth the watch. Would have been able to go through it more quickly in class. I won't hit these topics unduly as the central point of the test, but they will be on it. We will do a practice or two more in class, but this is worth watching. I talk about the test setup and go through a list of topics to review at the end of the video (also, add sig figs\sci notations and precision\accuracy to that list). If you have questions, call\email! God bless, hope the studying goes well, you guys are strong and capable of a ton, knock it out of the park :-)
Answers for Page 1 and Page 2 are now available. I didn't get a couple of the hw assignments, which is unfortunate. Nonetheless, please do take a look at them and the video, as they'll help with the test. Please call\send questions if there are some you still don't understand! Do your utmost, I am glad to have you guys for students :-)
