CHEMISTRY: Great job today… a little bit different lab procedure, huh?!! This lab is answered only on notebook paper – be careful to show correct data and calculations!
BTW – I think you’ll find that percent composition problems are really 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 chemical names for common substances so that you’ll have something to find the percent composition of!
