Chemistry 10-16-15 Mixture Separation Lab

Posted on by

CHEMISTRY: Pretty intense couple of days this week, huh? You know, I’m really proud of you! It’s one thing to be able to follow a set of directions, but it’s a whole other thing to be able to come up with the directions on your own! That’s a difficult thing to learn how to do, and you are doing a great job developing that skill.

Any questions about writing the lab report for Saturday? Be sure to save it as a PDF to your Google Drive shared folder. It might be a good idea to review the Digital Lab Report manuscript form and/or labs in Evernote that I have graded.

Be careful that you give me pertinent details on your procedure. Don’t be too general, give details. Also, if your plans changed, tell me that too. And then, after you write your own conclusion, don’t forget to include all Analysis & Conclusion questions after your own Conclusion – No Extension questions.

Hon Chemistry 10-16-15 Binary Molecular Formulas

HON CHEMISTRY: Okay, I’m not saying that learning to name and write chemical formulas is as bad as a jellyfish sting (you’ll get that in a minute!), but you do have to really, really pay attention to the details!! Here’s our discussion on writing formulas and names for binary molecular compounds. Part of it’s really similar to what you learned to do for ionic compounds, don’t you think? The other part is totally different, though!

Make sure you keep everything straight. Find a way to organize all the information for yourself so you won’t get confused. Also, don’t forget the lists you have to memorize – chemical names for common substances, polyatomic ions, acids, and numerical prefixes. And practice, practice, practice!!!

And did I mention polyatomic ions…..??
