We will take the ACS exam (a national exam given to all chemistry students) on Wednesday, 5/28/14. Your score on the exam will be compared to the national average and you could earn extra credit if you do well. Here are the topics that you might want to refresh because they are covered in several questions on the test:
I have attached the procedure corrections for our lab on Tuesday. Be sure to read the lab starting on page 211 and make the corrections to the procedure. This will count as homework points. Please let me know if you have any questions.
To help you study for your quiz on Thursday, please see the attached answer key to the yellow packet. The equilibrium notes page answer key is posted under the absent work page if you need it. Please let me know if you have any questions.
Are you looking for more points from your acid-base test? (UPDATED 5/20!!!)
Please make sure you BRING YOUR TEXTBOOK to participate in this opportunity. You will complete problems out of the textbook and earn back points on your test for each problem you complete.
Since we did not have time to get our acid/base test back on Tuesday and we are on a special schedule on Wednesday, the re-take for this test will be on Thursday or Friday mornings starting at 7:15am in room 453. Please plan your schedule accordingly as there are no other opportunities to get back points on this exam. Let me know if you have any questions.
Please make sure you are reading through chapter 18!!!!!!!! You can find a copy of the homework assignment for chapter 18 under the absent work section. This assignment takes the place of any homework problems out of the textbook and was handed out in class on Friday, 5/9/14.
SENIORS- You need to turn in your packet to my mailbox at the front desk when you come to take your final on Monday. You are expected to complete every problem except for #15 because we will not have discussed that.
If you are interested in improving your grade for the chapter 13 test, plan to complete a re-take on Tuesday, May 13th. The re-take will be before 1st period (starting at 7:15) or after 11th period in room 453. The written section will be available for you to re-take. In order to participate, you MUST turn in the written section that you received in class on Thursday, 5/8 before you begin the exam. There are NO other options to make up this test, so please arrange your schedule accordingly. Please let me know if you have any questions.
Please note that the numbers do not match the numbers on your yellow sheet because I added in a few more naming at the top. Also, know that any time you are asked to connect an ion concentration with a pH or pOH, there are at least 2 ways to complete the problem. Only one way is shown in the answer key, but if you completed the problem using the other "go-between equation" and got the same answer, you probably did the problem correctly. Please feel free to email me with any questions.
Our last extra credit quiz of the year is coming up on Wednesday, May 7th. The topics are the transition metals and the boron family. You can find the information in the elements handbook in the reference section in back of your textbook. The pages are R14-R26.
Please remember the following information from your course outline about the extra credit quizzes:
Quizzes are offered from 7:30-8am in room 453. You must finish early enough to make it to your first period class. I will not write notes to admit students to first period. Quizzes will be multiple choice, true or false and matching questions only. There will be 20 questions on each quiz and 1 extra credit point will be given for each point scored above a 12/20. Calculators are not allowed.
These 2 parts of your acid/base HW will be due on Tuesday, May 6th. Please complete the following problems:
pg. 480 # 1, 2, 3, 4
pg. 481 # 4, 5, 6
pg. R08-109 # 418, 422, 423, 426, 429, 434, 441
pg. 497 # 24, 25, 26
As of today (4/30/14) you should be able to complete all of the problems in part 4 of the homework. Part 4 deals with pH and concentration problems which we discussed in class on Monday and Tuesday. Part 5 includes titration problems which were discussed in class today and will finish up on Thursday and Friday.
Don't forget your test is on Thursday, 5/8/14. Please let me know if you have any questions.
Please find the attached answer key for the homework assignment to chapter 13. Remember to carry out several places after the decimal and only round to the correct number of significant figures at the end. Don't forget to bring your homework assignment on Monday to turn in. Please let me know if you have any questions.
