A WebAssign Review for your final exam has been posted.  (It's called "Honors Chemistry Review 1".)  This is NOT a required assignment, just a tool you can use to study for your final.  It will show the correct answer to each question after 3 submissions.

Remember to prepare your "cheat sheet" notecard to use on the final.  Handwriting only, no typed notes!

The Period 5 final begins on Wednesday at 12:20 pm.  
The Period 4 final begins on Thursday at 10 am.

Try to arrive at least 5 minutes before your scheduled final exam to give yourself time to get settled.

GOOD LUCK STUDYING!!!  WE ARE ALMOST THERE!!!

The key to the redox review packet as well as the key to the extra redox balancing practice sheet have been posted in the Unit 11 Keys folder.  Study session tomorrow at 7 am in the classroom.

Don't forget your WebAssign and good luck studying tonight!

Hi, Honors Chem, I completely forgot to tell you that MONDAY IS A CHEM DAY!  Yes, you get to go to a Chem Day...finally.  There will be a sign on the classroom door to remind you, but during our regularly scheduled class period, GO TO THE LYCEUM.  Be sure to complete the handout that goes with the video and hand it in to the substitute teacher (that's my attendance, so if you don't hand one in you will be marked absent).  

Please spread the word and enjoy Chem Day on Monday!

Hello Fellow Chem-mates....

In class on this beautiful day, we practiced some more with voltaic cells and determining which substances undergo reduction and which ones go through oxidation. When trying to figure out which one participates in which equation, there is a list of Standard Reduction Potentials in the packet we have been doing. Ms. Friedmann posted videos yesterday on moodle on calculating voltages in a voltaic cell. There should be a video of what today's lesson was on I think, but essentially today's lesson was a continuation of yesterday's lesson.

One new thing we learned today was the process of Electrolysis. We did not go over it thoroughly, but we discussed the concept in class a bit. When doing some of the voltaic cell problems, some of them ended up with a negative voltage value. This means that instead of producing electricity, it consumes it. This is electrolysis.

Homework:

1. Complete the WebAssigns that are due tonight
2. Finish page 7 in the packet (1pt Extra Credit = page 8)
3. Bring in a citric fruit and read the Fruit Battery Lab for tomorrow (in the Unit 11 Labs folder)

So, when we came into fifth period, Mrs. Friedmann checked in our homework.  She also said not to worry if we didn't understand the two redox equations that were homework because they were complicated.  The answers to them were...

      a. Na2Cr2O7 + 2HNO3 + 7H2O2 -> 2H3CrO8 + 2NaNO3 + 5H2O

      b. 3K2MnO4 + 4HNO3 -> 2KMnO4 + MnO2 + 4KNO3 + 2H2O


We also went over the homework on page two in the packet.  Then, we completed page 4 in the same packet.  I am pretty sure that Mrs. Friedmann will put these notes on moodle.


Finally, our homework is problems d and e on page 3 in the same packet.  Also, there is a webassign due tonight.  There are also two webassigns due tomorrow night.  One of these (called Redox equations) is for extra points that can be added on to our test.  Don't forget to add some easy points onto your grade!!

Voltaic Cells

May 12, 2014

We started class of by NOT turning in our take-home quizzes.  Instead of turning all of our work in, Mrs. Friedmann simply has us write down our answers to certain problems on a half sheet of paper so that it's easier for her to grade.

Mrs. Friedmann also explained the extra work that is now available to help boost your last test score. All you have to do is complete the WebAssign named Redox Quiz.  This assignment is due Wednesday night at 11:59.  The overall assignment is worth 10 points, and how it works is whatever you get on the WebAssign will then be added to your raw test score.  So, for example, if you got a 65/80 on your test and an 8/10 on the WebAssign, your new test score would be a 73/80.  Since this assignment can do nothing but help our grades, Mrs. Friedmann recommends that we all give it a try!

In class we started to learn about voltaic (galvanic) cells. We picked up a packet in the beginning of class and used that to take notes, so if you were absent make sure to print it out from the handouts folder! The notes aren't posted, but make sure to copy mine down if you don't have them written down.  We also used several colors to take notes with as an easy way to distinguish between reductions and oxidations.

Homework
1. Complete the top section of page 1 of the packet.  Make sure to show your work in your journal and write your final answer in the space provided on the packet.
2. Complete page 2 of the packet
3. Start on your WebAssigns! We have one due tomorrow night as well as one due Wednesday night.

5/9/14 Class

To start class, Mrs. Friedmann went over some homework questions from the worksheet on balancing redox reactions in acid/base solutions. Mrs. Friedmann also informed us that she has created a video going over numbers 3 and 4 that can be found on moodle. There is also a key to this entire worksheet on moodle.

We had a quiz that Mrs. Friedmann allowed us to take home to complete for homework. 

We also discussed another resource that can help us understand the unit so far called Kahn Academy Here's the link... https://www.khanacademy.org/

Homework:
Take home quiz!

4 Webassigns...
