Chemistry 8-29-18 Significant Figures HW & Scientific Notation

CHEMISTRY – I like the way you are catching on to significant figures! Here are the last of the notes on calculating with Sig Figs!

And great job with scientific notation today! Did you realize your calculator was so smart? Have you conquered it yet?

Remember, the best way to really learn all of the things from this chapter is practice, practice, practice! That’s the reason it’s so important to do your homework! I give it to you so you can practice and put together all we talked about in class ….cuz I love you! 🙂

Also super important – SI quiz tomorrow! Make sure you are actively studying for it, not just looking over it!!

Hon Chemistry 8-29-18 Conversion Factors

HON CHEMISTRY: So you can estimate out how fast you can drive in at least one parking lot in Guatemala – but can you show me how you solved the problem? Can I trust the validity of your work?

Good job on remembering how to use conversion factors! Remember, this isn’t just about getting an answer – some of you can do that in your head. This is about being able to convert from one unit to another using the Q-formula. (And yes, you have to do it that way!)

I posted a slightly different lesson from last year below – I turned on the mic today, but forgot to turn on the receiver!
