Chemblog!

Pretty good start on our first (and longest) test of the year: The class has an A average. I'll return your tests on Monday. Then, I would like you to analyze them and see me regarding anything that you got wrong or that you are not absolutely bulletproof on. You need to have the basics mastered so that you can smoothly navigate the rest of this course.

I will discuss this with you on Monday but, if you were anxious about the last two questions on the exam (the ones with the stoichiometry which led to the empirical formula), do NOT worry. You will see that I have made a reasonable accommodation for those questions while also rewarding those students who managed to correctly work out the problem (some of you were quite creative in doing so...amazingly good!). I will tell you my logical reasoning for doing so. Suffice is to say that we will be doing MANY problems like those in the upcoming unit. Those question types will be on your AP exam this year (question 2 or 3 in the written-response section) so I want to ensure that you ALL are experts on them.
In the meantime, hit the text questions assigned for HW this weekend. I will post solutions to them by Monday.
