Thurs-Day 1
AP Chem - we used our knowledge of the properties of metals and non-metals to predict the products of single replacement redox reactions. We reviewed other reactions learned throughout the course.
We discussed the relationship of the periodic trends of the table of elements to the characteristics of what we call "metals" and "non-metals". Elements that have low Zeff on valence electrons and many shells of electrons exhibit the most metallic character (e.g. cesium) . Elements that have high Zeff on valence electrons and few shells of electrons exhibit the most non-metallic character ( e.g. fluorine).

Bio - we discussed the various layers, structures, and functions of the parts of a typical plant leaf.
We then gave a detailed explanation of water homeostasis/regulation in a plant via the guard cells that form stomates/pores on the underside of a leaf.# posted by C @ 2:47 PM
