GUYS. WE'RE DONE.

I just want to say.

I'm gonna really miss you guys.

And you guys are all meanies for not signing my yearbook.

And stop asking for extra credit Bobby.

And shut up ____ (fill in as applicable).

And stop checking your grades.

And start enjoying life.

Cause *coughMrs. Friedmanncough* not everything's perfect.

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!!!

Tuesday, May 20, 2014

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!

:) Ms. F

Blog for May 15, 2014

What we did in class today:

HOPE ALL AP TESTS THAT WERE TAKEN THIS WEEK WENT WELL FOR EVERYONE!!!!! ;)

  • We checked in homework which was page 5 of the packet we are working on now
  • We got a Fruit Battery Lab Handout
  • We did a few problems from each page in the packet (6,7,8)
  • For page 9 of the packet only read the top section then cross off the rest of the page because we do not need to know that and page 10 for the test. 
  • We highlighted/color coded the top of page 9, so see someone else's packet if you were absent today. 
Announcements made by Mrs. Friedman today:
1.) The test is wednesday of next week
2.) There will be a review packet, review video and a review session as always
3.) Tomorrow we are going to do a lab, the only thing we need to turn in for the lab is just a finished lab packed and nothing else is required. 
4.) For tomorrow's lab, citrus fruits are the best to use.
5.) Answers to the chem packet we are doing in class is still not up yet, so don't worry Mrs. Friedmann is working on it still. 
6.) TRY TO DO A FEW REDOX PROBLEMS EVERY NIGHT, BECAUSE PRACTICE MAKES PERFECT AND MRS. F IS EXPECTING A 100% ON THAT SECTION OF THE TEST!!!!! 



RED Cat
AN OX










Homework:
1.) Do page 6,7 of the packet (THE FIRST ONE ON PAGE 8, WE ALSO DID TOO)
2.) Page 8 IS EXTRA CREDIT. (EXTRA CREDIT EXTRA CREDIT) 
3.) Remember to WEBASSIGN if you haven't done so already. And the redox quiz on their remember is a way to bump up your grade but it is optional.
4.) Bring in a Citrus Fruit for the lab tmrw. 


Remember practice practice practice because you don't want to be like this person. LOL


















HANG IN THERE EVERYBODY, ONLY A FEW MORE WEEKS TILL SUMMER!!! JUST A FEW MORE WEEKS ;)

BTW THE NEXT BLOGGER WILL BE ALLIE BOLAND!

Blog Post 5/14/14

We first checked in the homework from yesterday, which was pages 3 and 4 in our packets. The answers are most likely up on Moodle.

Then, Mrs. Friedmann had us balance a challenging redox equation at the request of certain students. The equation is as follows:
K2Cr2O7 + HCl + H2S ----> KCl + CrCl3 + S + H2O

As I type this, Mrs. Friedmann is making a video (which will probably be up on Moodle) that explains how to balance the above reaction. The video continues on to page 5 of the packet and goes over the text of question 7.

Homework: Page 5 of the packet. Webassigns are moved to Thursday night.

The next blogger will be decided by me tomorrow, based on whoever hasn't done it this quarter.

Stay classy, Bobby.

Class Blog - Friday, May 9, 2014


At the beginning of class, Mrs. Friedmann checked in the 8 redox reactions we balanced last night. A few people had trouble had with problems 3 and 4 of the base part, so Mrs. Friedmann made a video during class today going over how to do these two problems. The video will be posted on Moodle for all of the people who were absent.

Homework: We were given a partner take home quiz that will be due Monday. They WILL be graded for correct answers.

Class Blog 5/7/14

ONLY 17 DAYS OF SCHOOL LEFT!!!

We checked in the homework (3 worksheet pages)
Mrs. Friedmann didn't finish grading the tests yet.

Today in class...
  • Checked in homework
  • We learned how to balance redox- equations
  • The lesson is recorded and going to be posted by 9 tonight on Moodle. 

Balancing Redox Equations in Acid
  • Redox can happen in either acid or base
  • Acids have H+ and bases have OH-
In acids Steps:

      1.  Split equation into 2 half-reactions
      2.  Balance each half reaction:     
    • Balance all atoms Other than H & O
    • Balance oxygen using water
    • balance hydrogen using H+
    • Balance charges using electrons 
      3.  Multiply each half reaction by an integer so electrons for both half reactions are the same
      4. Cancel and Combine.

***There are 2 examples in the video(in the hw), but its too hard to type it out!!!***

Homework:
1) Forming Ionic compounds worksheet
2) Balancing Redox equations worksheet #1-8





Wednesday, April 30, 2014

Today in Chemistry when we walked in Mrs. Friedmann checked in our hw from last night.
 We then went over the hw and Mrs. Friedmann answered some questions.  

Next we took some notes on Titration:
 I know the concentration of a base.
What is the concentration of a certain acid?
#H's x Ma x Va = Mb x Vb x #OH's

HCl and NaOH
 # H's= 1        #OH's= 1

 H2SO4 and NaOH
 # H's= 2        #OH's= 1

H3PO4 and Ca(OH)2
 # H's= 1        #OH's= 1

neutralization:
HCl + NaOH ---> NaCl + H2O

We then observed Mrs. Friedmann conduct a brief Titration Lab.

HW:
1) Lab is due tomorrow
2) Start studying for test on Friday!

Monday, April 28th

Today, we turned in our take home quiz and there were 4 handouts about the labs today.

Then we got in to quick notes for the Lab

Indicators Lab

- An indicator turns one color at one pH is a different color at a different pH.
- Most indicators are weak acids. (HIn - means indicator)
A couple are weak bases

HIn (Color 1 weak acid) <-------> H+ + In- (Color 2 weak base conjugate)

- The indicator responds to changes in the [hydronium ion].

HIn <-----> H+ In-

                   <-------------------- Add base, shift to left (color 1)

Add acid, shifts to the right     ---------------->

These were the basic notes, the more notes for the actual lab are also posted in Moodle... According to Mrs. Friedmann

After some quick notes, we did lab to find the pH of 15 solutions experimentally.

For HW:
Hand in : Table of experimental data
                  Calculations of pH for 15 solutions (It is not Due Tommorow)
                  Webassigns on buffers, due tonight

Class Blog for Friday, April 25 :)

A note for: Melissa Frankie EJ and Kate

What we did in class today:
- Mrs. Friedmann put us in small groups and gave us a similar problem to the quiz yesterday. We worked through it and are beginning to understand the concepts of determining the pH of a salt solution. Be ready to perform similar operations to that of the quiz from yesterday, since the quiz didn't count for a grade. This is a learning process:) 
- After that, we went over the quiz. 

Next Blogger: Kevin J
Homework: There is a worksheet, and a webassign on buffers 

Enjoy your weekend!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


Class Blog 4-22-14

Hey Honors Chemistry! (Pulling a Mrs. Friedmann) So sorry this is late. I really have no excuse, I just totally forgot.

What We Did
  • Checked in homework from last night
  • Went over pages 8 and 9 (Our homework from last night)
  • Had a lesson on finding the pH of salts.
    • The lesson is recorded and should be posted on moodle
  • We didn’t get to buffers, so that will be taught on friday

Homework
  • 2 webassigns due Wednesday at midnight
  • Pages 10 and 11 in the Acids and Bases Packet
  • Study for quiz on Thursday.
    • We will have VERY short periods on Thursday, so it will be a short quiz.

Who doesn't like a good joke?
1. Girl, you’re a 10.

On the pH scale, because you’re BASIC!

OK, so...the video on yesterday's lesson was supposed to be uploaded by 7 pm last night, so on the bright side I'm only 17 hours late.  Sorry!  The link is at the bottom of the Unit 10 box on Moodle.  Tomorrow's quiz will be a problem similar to questions 34 and 35 on pages 10 and 11 of the packet, which the video covers.

Don't forget to enjoy the sunshine!  :)  See you tomorrow.

Ms. F

Tuesday, April 22, 2014

Hi, class!  Given that we have not yet discussed buffers in detail in class yet, I have elected to move the deadline for the Buffers WebAssign to SUNDAY NIGHT, 11:59 pm.  The other WebAssign (on Kb and salts) is still due tomorrow night (Wednesday 4/23) by 11:59 pm.  By Thursday you should also have completed pages 10 and 11 in the packet...for those of you absent today a video of today's lesson will be posted by 7 pm tonight.  Quiz Thursday, during our 20 minute period (it will be a problem calculating the pH of a salt).

Happy ICEing!

Blog 4-21-14

Welcome back, I hope everyone had a great 3 day weekend.

-We started today by checking in pages 6-7 in the packet.
-We then grabbed a packet of pages 9-11 that should be stapled to the current packet.  (moodle here -->Part 2)

Reminders
-Nothing in this unit is new, it is review just in the form of acids and bases

Review
pH= -log[H+]
pOH= -log [OH-]
pH+pOH=14
[H+]=10^-pH
[OH-]= 10^-pH

pH<7 = Acidic
pH=7 = Neutral
pH>7 = Basic

Strong Acids: HCl, HBr, HI, HNO3, H2SO4, HClO4
Strong Bases: NaOH, LiOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2

Notes
-Percent Dissociation
     -What percent of the original chemical undergoes dissociation?
     -Change (or X found in equation) divided by the original concentration.

-Conjugate Bases and Acids (VERY IMPORTANT)
     • The conjugate base of a weak acid tends to form basic solutions in water. 
     • The conjugate acid of a weak base tends to form acidic solutions in water. 
     • The conjugate base of a strong acid has neither acidic or basic properties. 
     • The conjugate acid of a strong base has neither acidic or basic properties.  


Homework
-Finish Pages 8-9 of the packet
-Try #34 on page 9 for possible extra credit
-2 webassigns due wednesday night

Hey y'all!

What we did in class is that first, we did the quiz.
Whoever didn't take the quiz, make sure to make up the quiz when you can!

Next, we went over some problems in the Acids and Bases packet.

NEED TO KNOW FOR SOME OF THE QUESTIONS:
pH= -log[H+]
pOH= -log [OH-]
pH+pOH=14
[H+]=10^-pH
[OH-]= 10^-pH

Homework: page 6 and 7 in the Acids and Bases packet.

Good luck y'all and have a great weekend!!!!!!

Today, we started class by going over the quiz.

Heads up! There will be a quiz on an ICE problem tomorrow. Be ready for anything, I suggest. There is also a web assign due tonight as per norm.

After that, we went over the homework.

Two important notes:

-In these ICE problems, the concentrations of H3O+ and OH- are very important!
-Small zero rule is always a good choice! (btw. In the small zero rule, you take out the x that is either being added or subtracted)

We went over 9a and 10a.
9a. Concentration of H3O+ should be .000035
10a. Concentration of OH- should be .003

Mrs. Friedmann will post up the key on Moodle.



On that note.
GOOD JOB HONORS ENGLISH STUDENTS! WE MADE IT!

Next blogger will be Elaine Sine.
