Chemistry 5-11-26 Intro to Acids, Bases & pH

Posted on by

CHEMISTRY: So what makes lemons and oranges taste sour? Great intro to the properties of acids and bases, indicators and pH!

UPDATE: Acid & Base Solutions simLab is going to be tomorrow. I’ll have it printed for you.

Info on 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.

Chemistry – Your LAST Web Post Comment!!

Posted on by

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!! 🙂

Chemistry 5-7-26 Chapter 4b & 5a Test Overview

Posted on by

CHEMISTRY: Wow! We finished! Here’s our overview of the test and start to some test practice.

Have you checked out the Ch 4b & 5a Stuff to Know Sheet?? Make sure you memorize the things you need to memorize so that you can apply them on the test. And practice, practice, practice, the different kinds of electron configurations.

God bless you! I’m praying for you!!

Chemistry 5-6-26 History of the Periodic Table & Overview of Blocks

Posted on by

CHEMISTRY: Great start to a new chapter – did you realize we did that?! Here’s our short look at some of the history of the periodic table and a look at the properties of the blocks and groups of the periodic table. We’ll finish the p block tomorrow

Chemistry 5-4-26 Noble Gas Notation

Posted on by

CHEMISTRY: Is it getting complicated? Great job with noble gas notation today!! Watch last Friday’s and today’s vodcasts again and it will make more sense the second time! It would also be great review for the test! Speaking of which – have you started checking the stuff to know sheet for the test??? Super important!!!

Chemistry 5-1-26 Electron Configuration Notation

Posted on by

CHEMISTRY: How’d you do with electron configuration notation today? Just when you were getting the hang of drawing arrows, I go and change it! But don’t you think writing electron configuration notation is a whole lot shorter than doing orbital notation? Don’t get me wrong, knowing how to do orbital is great for seeing how the electrons are paired, but this way is waaaay shorter!

Be sure and practice with the homework tonight, and don’t forget to use the Aufbau “chart”!!!!

Hon Chemistry 4-30-26 Gas Law Problems

Posted on by

HON CHEMISTRY: Here’s our second look at the gas laws, this time with numbers.

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!!
