CHEMISTRY – I like the way you are catching on to conversion factors! And great job with scientific notation today! Did you realize your calculator was so smart? Have you conquered it yet?

Need any extra help or practice? Help session tomorrow morning at 7:15ish A.M.

Remember, the best way to really learn all of the things from this chapter is practice, practice, practice! And just so you can do that, I’ve put it all together in your homework tonight….cuz I love you! 🙂 You can do it!!

CHEMISTRY 9-5-13 Scientific Notation & SI Practice from Tammy Skinner on Vimeo.

Do we need to do “B” part for #54 it’s asking us to compare our answer to the table of group 1 properties?

JD – Yes, check the Element Handbook section in the back of the book 🙂

Thank you for posting this! I need extra practice on scientific notation because I’ve forgotten is from last year!

In scientific notation, if a zero is a significant figure, do you include it in the notation? Ex: 5.300 x 10 to the second power … in this case, both zeroes are significant because of the decimal

Yes. 5.300 x 10^2 has 4 sig figs.

How high can you go up to when it comes to sig figs?
