CHEMISTRY: Great job today… although, it was kind of weird watching you chew gum in class! Double check your calculations, sig figs, etc. Remember you are finding the percent of SUGAR in gum, so that means the mass of what goes on top? Lab reports are due Monday.
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 common substances from #58, so that you’ll have something to find the percent composition of. Don’t stop practicing those as well!
I really understood this today!
Ms. Skinner, what time is the lab makeup in the morning on Thursday?
Hey Ms. Skinner, I understood this when we went over it in class today.
Sad that I missed today, but I did watch the vodcast. I found it pretty helpful so hopefully when I’m back it’ll be easy to jump back into things.
Just wondering? But will we still do the lab tomorrow or will I need to come fore a makeup day?
I like these! They’re pretty easy 🙂
that was a fun lab!
Thanks for teaching us these problems, they looks simple.
