Wednes-Day 1
Physics - we did Work and Energy 4 problems involving potential and kinetic energy calculations.
We did a lab showing the power generated in your doing the work of lifting your body up stairs in a certain amount of time.
AP Chem - we showed how to draw Lewis structures for "odd-electron" molecules; everything is the same except that the central atom ultimately gets 7 valence electrons instead of 8.
We then explained the reason for the relatively increased reactivity of radicals (lone single electron containing molecules), which are stabilized by reacting with each other or other molecules by forming a bond between nuclei using their lone/single nonbonded electron.
We used the example of nitrogen dioxide reacting with another nitrogen dioxide molecule to form dinitrogen tetroxide. This process is called DIMERIZATION.
