Ionic Compounds with Polyatomic Ions

Well, first things first. If you need a refresher on naming Ionic Compounds click the link below to be whisked back in time to the summer of love, otherwise known as November of last year and a post I wrote about how to name molecular and ionic compounds…

The Name Game (November 20, 2012)

Now, naming an Ionic compound that has a polyatomic ion in it is just as simple as naming any other ionic compound. It’s simply…

The name of the metal (space) The name of the Polyatomic Ion

PI1

The trick is that you need to know the names of the polyatomic Ions. Here is the first group of them (figure on the right). Here are the rules for naming polyatomic ions:

  1. “-ate” has 1 more Oxygen atom than “-ite”
  2. If you add an Oxygen to an ion that ends in “-ate” add the prefix “per-” (ChlorATE = ClO3 // PERchlorate = CLO4)
  3. If you subtract an Oxygen from an ion that ends in “-ite” add the prefix “hypo-” (ChlorITE = ClO2// HYPOchlorIte = CLO)

The entire molecule, NO3 for example, has a charge of  -1. So lets say I was joining Nitrate (which is NO3) with Magnesium…
Well, Magnesium’s charge is 2+ so how many Nitrate Ion’s would I need? If each NO3 has a charge of -1 then I need 2! So The formula would be…

Mg(NO3)2

The parentheses go around the entire polyatomic ion because the entire ion has a charge and therefore I need 2 of the whole thing.

So, to name the formula, I just use the names of each part: Magnesium Nitrate!

All the same rules for Ionic compounds still apply (Charges must balance & Metals with multiple charges get roman numerals). Try the first set of polyatomic Ion problems (Practice #1) and then move on to the 2nd group of Polyatomic ions, shown at the bottom, and then try their practice problems (Practice #2).

Common Assessment #1

Step 1: iOS 7 – Bring up the toolbar from the bottom of your screen and TURN ON your DO NOT DISTURB Button

iOS 6 – Go to your settings and TURN OFF notifications or TURN ON do not disturb.

Step 2: If there are people sitting behind you facing you, set your flat on your table; otherwise set your iPad up so that it faces you. Make sure your screen is bright enough to see from this angle.

Step 3: Click the link below and begin your Fall 2013 Common Assessment

Step 4: Please fill out honest the Student Feedback Form so that I can improve my teaching (or keep doing what I’m doing)

Student Feedback Form: Quarter 1 – Google Form

Step 5: Work on something Academic for the remainder of the time alotted.

Class Agenda for 9/25

Biology: Follow these directions to help better prepare you for your test, which is scheduled for October 4th (Next Friday!)

  1. Complete your cell coloring
  2. Do the cell crossword puzzles (Label the parts as you fill in the crossword)
  3. Follow the directions listed below to create your own review quiz!
    1. Go to drive.google.com
    2. at the very bottom of the page, click the link that says ‘desktop’
    3. if the page appears with a warning, click ‘continue to desktop version’
    4. to the left of the new page, click the red box that says ‘create’ and then click ‘form’ on the drop down menu
    5. It will then open a new page with a pop up box
      1. Title: Your Name Cell Review
      2. Choose a skin
      3. press ‘ok’
    6. For your first question, put “Name:” in the question title. Then change the question type to ‘text’. Click ‘required question’  and then press ‘done’.
    7. Now press ‘add item’ and start writing your 1st of 10 questions. You can choose to make the question multiple choice, a list, text, or a paragraph. When your first question is finished, press ‘done’.
    8. To add your next questions press ‘add item’ and repeat #6.
    9. Once you’ve made your 10th question click ‘View Live Form’ in the bar near the top. This will allow you to preview your quiz and see how others will view it. If it is ready to publish, click the bar at the top that says ‘drive.google.com’ and it will change to the link for your specific quiz. Copy the entire link.
    10. Now, at the bottom of this post you’ll see a link that says ‘# comments’, click that link
    11. When the comment box appears, paste your link. Below that put your school email address in the email box, and your name – period in the name box.
    12. Finally, once you have posted your quiz, complete 3 quizzes from other students in the same period as you. Feel free to complete more than the three or complete quizzes from other classes too.

Tomorrow, I’ll show you how to check your responses so we can make sure everyone completed their assignment. Good luck making your quiz and email me if you have any questions. Have a great Wednesday!

Chemistry: Complete the Ch. 25 discovery questions (available as a PDF on the Chem page) using the iBook. Feel free to work with a partner.

Test(s) Monday!

Honors Biology and Academic Chemistry…

Both classes have their Unit 2 test on Monday. I would really rather not do a test right after a weekend, but if you have concerns or questions please ask me on Friday! (remember tomorrow is our Day of Service and Friday’s classes are shortened for Counties and Mass)

The study guides are posted, and I will post answer keys to them this weekend.

Biology… pay special attention to the Vocab List.

Chemistry… pay special attention to the calculations (# of atoms, molar mass, % comp, and energy transfer).  Go back through my older posts (Like this one)for review.

Sorry to disappoint, but…

Try not to be too upset that I’m not there.

I have a family emergency and won’t be able to come in today. I will try to have the tests graded ASAP but the important info is what you will be doing today in my absence.

Chemistry: Follow the directions on the board and find the video and documents on the Chem. Semester 1 page.

Biology: Complete the steps listed on the board in order.

  • Complete the warm up on a new “Note”: 
    1. What is an atom?
    2. What is an element?
    3. What is a bond?
    4. T/F – In the living world of anything determines it’s function
  • Watch this YouTube video over the notes we were going to take today
  • Do the “Periodic Table Labeling” on the back of your packet
    • The instructions are located at your table (please leave them there neatly at the end of the period)
    • Colored pencils and markers are located in the back. Please take what you need, share, and return the items when you’re done
  • Complete the Chemistry Practice tables in the middle of the packet as homework

Please stay on task and do not disrupt others who are trying to work… or you might have this guy show up to class on Wednesday

From the U.S. Dept. of Health & Human Services

We have been contacted by the U.S. Department of Health and Human Services to give input into what could potentially become a national crisis. To this point, the threat is real but the problem is still a few months from coming to fruition.

Key West Needs Water

The tiny tourist destination is on the verge of a crisis. Please read the details in the attached powerpoint and forward your plan on to Mr. Kubuske. After all the plans have been gathered, we’ll send them on to our contact in Washington.

Lab Safety… it’s no Accident

Today we’ll be going over some important information about your safety in a Lab setting. After review the Lab Safety rules (check the documents page for your specific class for a PDF version), take a look at the image below. See if you can spot some incidences of failing to follow lab procedures for safety.

Reminder there will be a “Common Sense” Lab Safety Quiz tomorrow for Biology and Chemistry
