Hon Chemistry 10-21-11 Percent Composition

HON CHEMISTRY: Great job today… although, it was really weird watching you chew gum in class! I think you’ll find that percent composition problems are super easy to catch on to. Make sure, though, you can write chemical formulas (I won’t give them to you!) and that you’ve memorized the formulas for acids and those common substances from #58. Then, it’s just plug and play from there! 🙂
