Week of 10/26

Monday: Gas Laws Simulation Lab Tuesday: Today we went over the Dumas method of determining molar mass.  We did #13 in the packet (and connected to empirical formula).  Then I gave you a copy of this set of procedures and data to see how you could do this experimentally.  Real value was ethanol.  The last bit of […]

Week of 10/19

Monday: Your goal is to figure out which alkali metal it is.  As a group you will write procedures that will both explain the procedures and the calculations behind the procedures.  You will do the lab on Monday and hopefully have enough time to do the calculations. Homework will be to write a conclusion.  Grades will […]

Week of 10/12

Monday: No school – Columbus Day Tuesday: Today we went over gravimetric analysis (see videos on unit 2 page if you missed them or need help).  I showed you how vacuum filtration works and we did the lab based problem on page 22 of the packet.  This is actually the answer, but we just covered […]

Week of 10/5

Monday: Review for the stoichiometry test tomorrow.  We started with homework problems and it became apparent that most of you had not done much limiting reactant work so we started going over the first problem on the limiting reactant section.  This was helpful because some of you were thinking of this in terms of atoms rather […]
