This assignment will be due on Tuesday, May 7th.
 

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 use the following information to help you complete the lab:

 

Part 1:

reaction with NaOH is a dissociation equation

reaction with HCl is an ionization equation

 

Part 2:

reactions with zinc are single displacement reactions - use your activity series

reactions with calcium nitrate are double displacement reactions - use your solubility chart

 

Part 3:

reaction is a double displacement, but one of the products is unstable and breaks down so there are really 3 products here!

 

Part 4:

reactions form only 1 product

 

Part 5:

neutralization reaction

be sure to include the formula equation, the complete ionic equation, list the spectator ions and the net ionic equation.

 

This lab is due on Monday, April 29th.

Please let me know if you have any questions.

Period 2 & 3:  We will look over the assignment together on Tuesday, April 30th.

Period 7/8 & 10:  We will look over the assignment together on Monday, April 29th.

Here is some information about your chapter 13 test:

 

20 scantron questions (matching, multiple choice, etc)

9 written questions including:

      -boiling point elevation/freezing point depression math problems

      -creating balanced chemical equations (using your solubility table to predict the states of the products)

      -forming complete and net ionic equations

 

GOOD LUCK STUDYING!!!!!!!!

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.

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.

It has been a while since we broke this out, so if you happen to have misplaced your copy, please print out one below.
