Fri-Day 1
Bio 3/6- we carefully examined the sequence, structure, and various changes that occur in the blood as it goes through the "cardiac cycle"/heart cycle to the lung capillaries and to all of the capillary "beds" throughout the body.
Please review and study the animation of the cardiac cycle that is posted on Blackboard.
We discussed the parts of the human transport system, in general: the pump/heart, the fluid/blood, and the tubes/arteries, veins, and capillaries.
We contrasted the structure and function of arteries, veins, and capillaries and noted the special features of each.
AP Chem- check Blackboard for a practice exam (no answer key; email or come to extra help if you would like an opinion on the sufficiency/quality of your written responses!) related to Monday's exam. The questions on the exam cover some but not ALL of the questions that will appear on Monday's exam (the rest of the question types are covered in the previously posted files and notes).
In general, on Monday's exam, make sure that you know in detail:
- how to draw the correct Lewis structure for any molecule
- how to determine hybridization, electronic geometry, molecular geometry, bond polarity, molecular polarity, and the resulting intermolecular force(s) of attraction for each molecule; also relate the IMFA's to physical properties such as boiling point, and vapor pressure at a given temperature.
- know the relative strengths of each IMFA and the reason(s) for the relative strengths
- know the explanation of why "like dissolves like" down to the molecular level and the related explanation of how ionic substances are either soluble or insoluble in a polar solvent
- know how to construct a phase diagram from basic data (as in notes) and deduce phase changes, relative phase densities, etc.
- know the different types of solids and the explanation of the IMFA's or BONDS involved in each type
- know all of the descriptive chemistry reactions that we have done all week and how to write their balanced net ionic equations including phase labels
- there are NO questions on this exam from our new unit on Kinetics (we just started that!).
