Hon Chemistry 10-20-17 Chemical Formulas Review & Intro to 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 review of the chemical formulas from last night’s homework AND an intro to writing formulas and names for binary molecular compounds.

Don’t freak out about binary molecular formulas! Part of it’s really similar to what you learned to do for ionic compounds, don’t you think? The other prefix 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? The quiz on them has been moved to THIS COMING Tuesday! Are you getting ready??

  1. Ok so the general struggle of this week is the formulas. I’m having a really hard time with these formulas but I can get a better understanding day by day. Feeling hopeful 🙂

  2. This week’s triumph for me is studying for the chemistry test and being confident before taking it. I feel like a did much better than last test. I also did all of my homework. However im struggling with the chemical formulas so I will look over the videos over the weekend.

  3. I would rate myself a 3.5/5 this week. A struggle I had was understanding how to write formulas. A success I had was making flash cards for the poltyatomic ions.

  5. A struggle this week was understanding how to write chemical formulas. It isn’t that it is hard but it’s just a lot to grasp. Hopefully I discipline myself and study appropriately.
