Wednesday Recap
I will try to have all Regents and Honors tests returned by tomorrow. In Honors, although there are about 12 scores in the 90s, there are a lot of outright failures due to an OBVIOUS lack of preparation and failure to follow directions. OWN your mistakes and make sure that they aren't repeated. That's the most important thing that you can do in this course.
I should have the AP exams graded by Friday.
G, D Honors: finished the evidence and conclusions of Thomson's experiments that led to the "Plum Pudding" Model of the atom. Thomson also used his measurements to deduce the charge to mass ratio of an electron; that, along with Millikan's Oil Drop experiment that deduced the charge of an electron, led to the calculation of the mass of an electron.
We will further discuss the experiment that led to the more accurate AND precise Rutherford model of the atom.
E: finished up gram to mole to atom and vice-versa calculations. Make SURE that you know how to set up these calculations AND that you know how to use your SCIENTIFIC calculator for them (NO graphing calculators will be permitted on any future exam).
We will discuss the evolution of the models of the atom on Thursday and Friday- see Chapter 4.2 of the text.
AP: finished the Van der Waals equation for real gases and explained the meaning of the a and b correction factors and how to predict their relative magnitudes. Try the descriptive chem set tonight. We will discuss that tomorrrow and then we will start THERMOCHEM...it's all about energy changes during reactions and phase changes.
