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!!
Chemistry Exam Help Session Thursday morning, 7:20ish A.M. (Honors Chem can come too!). EXAM ROOM ASSIGNMENTS are listed below. IMPORTANT – Bring your exam review packet to the chemistry room before you go to your exam room!
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!! 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 sciencegeek.net, they’ll 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!
EXAM ROOM ASSIGNMENTS are listed below. IMPORTANT – Bring your exam review packet to the your exam room on THURSDAY. God bless you, I’m praying for you!!
Honors Chemistry 302 Miller (Mr. Wilson’s room)
Chemistry – 2nd Period 303 Tapp
Chemistry – 3rd Period 304 McKenzie (Mr. Henderson’s room)
Chemistry – 4th Period 305 Clayton
Chemistry – 6th Period 310 Jenkins
CHEMISTRY: Awesome lab today! Great intro to the properties of acids and bases, indicators and pH! And how about that beautiful art you created applying this new found knowledge!
How’s the exam review packet coming along? Help session for the exam this Wednesday morning, 7:15ish A.M. Update on the exam review – omit #59 on the exam review packet.
HON CHEMISTRY – Who knew – chemistry and art!! Great work using pH with electrolysis today!
How are you doing on calculating pH? Acids mean H30+ ions and pH, bases mean OH- ions and pOH. Get the pH of an acid straight from the concentration of the acid. Get the pH of a base by first finding the pOH straight from the concentration of the base and then subtracting that from 14. No problem!! So how do you think someone would use pH?
Don’t forget about learning those indicator colors I told you about. Can you think of anything else that might be a natural indicator? What about tea? Have you noticed how it changes to a lighter shade when you add lemon?

CHEMISTRY – Tons of cool applications today using gas laws! Boyle’s Law, Charles, Law, Gay-Lussac’s Law – who knew?!
HON CHEMISTRY Great intro to the properties of acids and bases! Can you think you of ways to apply these concepts? Let’s talk more about pH next week!

CHEMISTRY: From running on snow to scuba diving – a great discussion about pressure and gases. Go play with the gas laws this weekend and we’ll take it up again next week!

HON CHEMISTRY: Major day today, huh?!? But pretty cool!!! Good job with the applications of the ideal gas law! Who knew you could go around the world to find density??
Here are some answers below – FYI. Now, go play – and don’t forget to memorize R!!
42 c) 0.0429 g SO2
43 c) 0.0112 L H2S
44 c) 93.8 L O2
45 c) 15.9 g Cu
46) 29.0 L CO2, 58.0 L H2O vapor
49 c) 1.06 atm
50 c) 3.81 L O2
51 c) 0.0377 mol
52 c) 0.299 g SO2

HON CHEMISTRY: Okay, for the record, water balloons do not obey Avogadro’s Law, but gas balloons do! Equal volume balloons contain the same number of molecules. And how about the Gay-Lussac’s Law of Combining Volumes? Yay, more great conversion factors!! How are you doing with blending the old and the new?

HON CHEMISTRY: Our first look at the gas laws: Boyle’s law, Charles law. No audio on the vodcast, so here’s a blast from the past. And you get a bonus – Gay-Lussac’s law. These guys did great work – and you’ve got to love their hair!!
Be sure you use Kelvin in the problems – not Celcius. And make double dog sure you use the formulas correctly! Rearrange that thing – no plug and play!!

CHEMISTRY: Wow! Can you believe we finished all 17! Here’s the lecture on the rest of the activity series and double replacement and combustion reactions. Now that you’ve got everything on paper, it’s time to practice!
Need some extra help? Help session? Let me know and I’ll be glad to schedule one!
