Thursday
We conclude our abbreviated week with Pep Rally Day tomorrow. Good times.
Our classes are cut short so be ready to work fast as soon as class begins.
AP: we did another descriptive chem set drill; take good notes on all of the sets including any mention of colors or other physical properties of reactants or products (e.g. iodine solid is dark gray; iodine vapor is purple; SO2 gas has harsh, toxic fumes that cause choking).
We started thermochem and introduced the concept of universe= system + surroundings (the equals sign means "duh"). We talked about work, heat, and changes in internal energy; we discussed the Zeroth and 1st Law of Thermodynamics: energy can neither be created nor destroyed a.k.a. deltaE = q + w . More on that important law tomorrow.
Honors: D,G covered the Rutherford Gold Foil Experiment evidence and inferences/conclusions; download the videos of that from the class website, study and enjoy! In D Period, we began to discuss the next major improvement in the atomic model: the Bohr Model of the atom. I will give out the Orange Review Books tomorrow.
Regents: we explained the Thomson Cathode Ray tube experiment (see videos on website) and then the Rutherford Gold Foil Experiment, which we will continue tomorrow. Watch the Rutherford video from the class website. I will give out the Orange Review Books tomorrow and I will assign some review questions and some grams to moles to atoms questions from that book. If you have the Barron's Blue Review Book, check that you have the 4th Edition because that edition has the correctly assigned page numbers for hw.
