Our last extra credit quiz of the year is coming up on Wednesday, May 8th. 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.
Please note that number 20 is missing and some of the work/explanations that we went over in class were more complete than this answer key. Also, remember to carry out calculations several places after the decimal (not shown here!) within the problem and only round to the correct number of significant figures at the end. This key combines both parts 1 & 2 of the homework assignment for chapter 13. Please let me know if you have any questions.
With all of the weather craziness, the test has been moved to Thursday, April 25th. We will begin discussing acids and bases on Monday. If you missed your review today, please see me with any questions you may have for the test. The homework answer key will be posted below as well to help you with any questions on your homework.
If you are using webassign, please find your assignment there. Here are the problems you should complete if you are working out of the book:
# 2, 8, 9, 11, 12, 13, 25, 26
Due to the late start schedule on Monday, April 15th, all classes will have the chance to ask any questions on the assignment on Monday before turning in the assignment on Tuesday. We will not be discussing the assignment on Tuesday before turning it in. Please let me know if you have any questions.
