Hon Chemistry 11-15-21 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! 🙂

Chemistry 11-15-21 Chemical Formulas with Polyatomic Ions

CHEMISTRY: How about cranking it up a notch?! First we did binary ionic compounds, and now, let’s tackle formulas with polyatomic ions. Something absolutely necessary – you have got to memorize polyatomic ions – or better yet, learn them! And practice, practice, practice!!

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!!
