***Any of the worksheets that we started in class DO NOT NEED TO BE FINISHED FOR HW.***

Oct. 14, 2016

In the textbook: do SR#1-7 on p. 85.  There will be a quiz on atomic theory basics on Thursday, Oct. 20.  The study guide will be handed out next class.  This will not include mole calculations; rather composition of atoms (protons, neutron, and electrons) and their written format (hyphen and AZX), and isotopes.

Oct. 18, 2016

We practiced writing ionic formulas and naming ionic compounds today.  We did watch a video about naming ionic compounds with transition metals in them: https://www.youtube.com/watch?v=Rq0A-AHdB74  I strongly urge you to watch this as there is a lot of valuable information in it.  For HW: complete the "Ionic Compound Formula Writing worksheet".  Only 1 side!

There will be a test about writing and naming ionic compounds on Thursday before vacation.  **If you missed the make-up lab this week (shame on you!), you will have one more opportunity on Tuesday after school.  This will be your last chance!**

Dec. 20, 2016

We practiced writing ionic formulas and naming ionic compounds again today. There are several practice worksheets available for you to practice on.  You need to practice to get good at this, so I advise you to consider doing at least part of all of them so you can practice different approaches to identify and name ionic compounds.

HW: study for the test on ionic bonds, how to make ionic compounds and how to name them.

Dec. 22, 2016

If you missed class today, we watched a short video about the difference between ionic and covalent bonding.  I suggest you watch on your own as we will start covalent bonding after the holiday break.  Here is the link: https://www.youtube.com/watch?v=PKA4CZwbZWU

Your test has been sent to your study hall teacher.  I expect that you will take the test by Friday.

There is no HW.  Have a great vacation!

Jan. 27, 2017

Complete the percent composition worksheet (both sides).  You are given the name of the formula; you will need to translate that into a chemical formula, balanced for charges (don't forget this part!), before you can calculate the molar mass, and the % composition of each element.  You do not need to complete the online curriculum assignment-we will finish in class next week.

Jan. 31, 2017

Feb. 8, 2017

Working with ONE partner, do the calculations for Mole Flight 1023.  You may work together, but everyone should be working on calculations.  Be sure to fill in the identity of the compounds found along with their empirical formulas.  If your formula does not match something on the chart, your math is wrong.  Identify the passengers and the evidence that you used for their ID, and finally identify the murder victim and the culprit.  Remember to identify the substance at the site of the explosion (% composition is listed at the top of the front page), and certify your work.  You and your partner can both certify your work, and submit 1 final copy for a joint grade.  You can submit your work, but it is not required as I will know from your conclusions if you were right.  If you want me to check it over, I am happy to do so.  Obviously, you will have to communicate with your partner electronically on this assignment as we will probably have a snow day tomorrow.

Feb. 14, 2017

Finish the Composition of Hydrates worksheet.  You should have completed some of it in class.  In addition, in preparation for the lab on Thursday, complete the pre-lab worksheet on the back side only (naming of hydrates).  We will review the front side with lab safety concerns on the day of the lab.

Feb. 16, 2017

Today we did the hydrate lab in class.  If you were absent, you MUST make it up with me after school.  I would like to schedule it either Tue, Wed or Fri after school.  Please see me so we can (hopefully) set this up so everyone can do it all at once.  For HW: you are to complete the "Determining the Formula of the Hydrate" worksheet.

Complete the "Word Equations" worksheet.  You only need to focus on the formula equation (all formulas are balanced for charges and written properly) tonight.  Make sure you write it as an equation: A + B → C + D.  We will learn how to balance equations next class.

Lab report rubric handed out in class today.  Your lab report will be due on March 14.  You are expected to include your calculations, and how you determined the formula for the Cu (II) SO4 hydrate.  You should do some research on hydrates, and be sure to include cited references.  No graph for this lab.  You will use Turn-it-in to check your references.

March 1, 2017

Now that you have the formula equations for the "Word Equations" worksheet, you need to balance the equations for atoms.  We will review the balanced equations next class.  In addition, complete the "Balancing Act" worksheet, including the opening paragraph at the top of the page.

Complete both sides of the "Worksheet 6.2 - Word Equations".  The front side asks you to translate the word equations to formulas and balance them, and the second side is just balancing formula equations already given.  Complete the "Formula Balance" worksheet started in class.

March 7, 2017

Complete the "Formula Balance 2" worksheet.  In addition, on the "Word Equations" worksheet, translate the statements into a formula equation (balanced for charges, but not atoms), and then use the formula equation to balance the chemical equation.  This will be what is expected on the upcoming quiz.

Study for quiz on translating word formulas into balanced chemical equations and back again.
