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!

Chemistry 5-18-17 Intro to Acids, Bases & pH

Posted on by

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 5-16-17 pH & Indicators

Posted on by

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?

Hon Chemistry 5-8-17 Molar Volume of Gases & Gas Stoichiometry

Posted on by

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 5-3-17 Gas Laws

Posted on by

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!!
