Are You Ready for the Exam?!?

WOW! It has been an incredibly awesome year for me, and I hope it has been for you too! God bless you as you are studying for your chemistry & honors chemistry exam! If you need a break, check out this awesome review of the elements: The Element Song or this New Periodic Table Song, but don’t get distracted by the challenge!!

EXAM ROOM ASSIGNMENTS are listed below. IMPORTANT – Bring your exam review packet to the chemistry room before you go to your exam room! (And the chemistry textbook if you checked one out!!)

It is super, super important so study YOUR VERY BEST and remember to practice, practice, practice! This exam can make a HUGE difference in your average. FINISH STRONG, like you’ve been working all year!! Produce something!! Make flashcards out of the vocab, formulas, types of chemical reactions, etc. Practice writing chemical formulas, balancing equations, working the problems – try the practice tests on the online textbook or on The Physics Classroom (sign in as a guest) or sciencegeek.net. All of these will be really helpful. And get yourself plenty of snacks! 🙂

How’s the exam review coming? You know, I don’t just give you that thing for the extra credit. I give it to you because it will help you get organized and help you remember everything that’s going to be on the exam. As you answer each topic, keep studying it, if you’re having trouble!

Hon Chemistry 5-16-22 Intro to Acids, Bases & pH

HON CHEMISTRY: So what do you think would cause these beautiful colors? Great intro to the properties of acids and bases, indicators and pH! Don’t forget The Physics Classroom assignment. If you need help on the last two levels, click on the Help Me button. It will give you the pH chart that matches certain indicator colors. Here’s a hint – Phenolphthalein indicator is always hot pink/magenta in a base.

And last hint – the more negative the H3O+ concentration (that means the higher the negative exponent) the more of a base that it is. The lower the number of the exponent (which actually makes it a higher number) the more of an acid it is.

How’s the exam review packet coming along? Help session for the exam Thursday morning, 7:15ish A.M.

Hon Chemistry 5-10-22 Intermolecular Forces & Ionic Bonding

HON CHEMISTRY: So how ’bout Johannes van der Waals and those intermolecular forces? Tons of application, from bugs walking on water to little fishes breathing dissolved oxygen. And what about the condensation that forms on the outside of an iced tea glass? Hmmm….

And then on to a different way that atoms come together – ionic bonding.

Keep in mind that when you write ionic bonding, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. And make sure you put the dots in the right order!

Chemistry – Your LAST Web Post Comment!!

Can you believe it?!? This is your LAST web post comment!! This is where you put it and here are the three things I want you to talk about:

1) How did chemistry grow you? What did you learn about yourself?
2) What advice do you have for future chemistry students?
3) What could we have done different this year that would have helped you learn chemistry better?

Can’t wait to hear from you!! 🙂

Hon Chemistry 5-6-22 Molecular Geometry & Dipoles

HON CHEMISTRY: Who knew we’d be doing geometry in chemistry?!? Great job today! Lewis structures, multiple bonds, resonance, polyatomic ions, and now molecular geometry and dipoles. Wow, that’s a lot you’ve conquered in the last few days!!

Molecular geometry is super easy. Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Here’s a copy of Molecular Geometry Shapes – VSEPR handout. Be sure and memorize the shape and the ABE structure that goes with it. Easy-peazy!

Dipoles take a second to think about, but you can do this! So why is molecular geometry important? What’s the big deal about knowing the correct shape of molecules? Here’s the beginning of the answer!

Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!

Hon Chemistry 5-5-22 Resonance & Polyatomic Ions

HON CHEMISTRY: Are your eyes playing tricks on you yet? 🙂 Great job working with multiple bonds and polyatomic ions with Lewis structures today!

Here’s some good advice – don’t take shortcuts. Learn the proper steps on the easier molecules, and you’ll be able to do the hard ones. And if it’s still all Greek to you, don’t worry! Keep practicing and you’ll get it, I promise!! Don’t forget to count electrons and don’t forget CONS!

Honors Chemistry 5-4-22 Lewis Structures & Multiple Bonds

HON CHEMISTRY – I just love dots! Incredible job today with Lewis structures!! If you were absent, be sure and watch this vodcast for some great hints on making Lewis structures easier. And make sure you practice, practice, practice! Warning: before you know it, you’ll be seeing dots everywhere!

Hon Chemistry 5-3-22 Intro to Chemical Bonds & Covalent Bonding

HON CHEMISTRY: Hey guys, welcome to chemical bonds! How did you do on using electronegativity to determine bond type? Make sure you add the scale and also the diatomic molecules to your “things I have to memorize and know how to use for the test” list.
