Chemistry 11-5-19 Chemical Formulas with Polyatomic Ions

CHEMISTRY: Great job today! Do you understand better now? Remember it’s like baby steps, first binary ionic compounds, and now, formulas with polyatomic ions. Begin learning how to do them now! And practice, practice, practice!!

Speaking of – how are you doing with polyatomic ion memorization? Quiz tomorrow!

Another great idea, click here for a copy of the Hints for Naming Chemical Formulas Flow Chart, or find it under the Worksheet/Handouts Tab. Follow it every time you name chemical formulas!!

Hon Chemistry 11-5-19 Percent Composition

HON CHEMISTRY: Great job today! Way to apply chemistry to your everyday life!!

I think you’ll find that percent composition problems are super easy to catch on to. First, though, be sure you know which “type” of percent composition you’re trying to fine. Also make sure you can write chemical formulas (I won’t give them to you!) and that you’ve memorized the formulas for acids and those chemical names and formulas for common substances. It’s just plug and play from there! 🙂
