5/6/10

Ok I don't know if there was a scheduled blogger for tonight but I need posts so I am going to go ahead and give one.

I (and many others) failed the quiz today so Dr. B. is letting us retake it tomorrow. You need to know how to calculate molarity and how to use acids (H3O) and bases (OH) in calculations. You also need to know how to apply pH and pOH in calculations. In addition, you need to be able to tell weak acids apart from strong acids and weak bases apart from strong bases. Good Luck!

    I would study again even if you are content with your current grade because even if you do worse this time she might let you keep your old grade.
