Thurs-Day 1
Physics - finished up the electroscope lab and the mechanical energy lab - hand those in by Tuesday (we are off on Monday!)
Did one more "system of charges" problem, and then we took part two of the electrostatics exam - the first exam to contain a "how"/"why" explanation until "then nothing would NOT BE...something has to ISN'T!"
Conversions of various measures of concentration: molarity, molality, percent mass, etc.
Did I leave anything out that we spent time on?

AP Chem - did a couple of problems in which we determined the rate of formation of a reaction's product based on the rate of consumption/disappearance of any of that reaction's reactants.
We emphasized the difference between "rate of reaction" in change in molarity of "reaction" per second and "rate of appearance or disappearance of a product or reactant", respectively.Our Solids/Liquids/Gases/Solutions/Metal-Ligand/Colligative Properties exam is postponed until next WEDNESDAY. We are off on Monday, and Tuesday we have a single period.
We will be able to get well into the kinetics unit before the weekend, at least.
Here are a list of question types on Wednesday's exam:
Colligative Properties:
- questions on relative freezing point, boiling point, vapor pressure, or osmotic pressure in a given solvent (the problem we did in which we calculated the (i x m) for each solution).
- question in which the molar mass of an unknown is found, the actual van t'Hoff factor is measured (versus the theoretical "i"), the vapor pressure lowering effect of a given solute in a given solvent is calculated
Raoult's Law calculation of the vapor pressure lowering effect of a given solute.
Solids:
- questions on the various types of solids, their type(s) of either IMFA's or bonds, and an explanation of how the bonding or IMFA causes certain physical properties i.e. melting/freezing point, electrical conductivity, etc.
Liquids: cause of vapor pressure, and explanation of the relative vapor pressures of a set of substances
Phase Diagram construction and analysis.
Conversions of various measures of concentration: molarity, molality, percent mass, etc.
Metal- ligand complex formula writing and naming
