Chem 5 - discussed calculator work for gravimetric determination of ionic mass of M 3+;
was missing a "3" in the numerator for sulfate; go over tomorrow, showing alternate solutions for percent mass of M 3+ or even just for S !
Go over test; sig figs. Do 4 gas forming reactions.

Introduced proper stoichiometry, and determination of limiting and excess reactant.
Showed the meaning of "moles of reaction".

Began butanol combustion stoichiometry question up to moles of reactants and ratios.

7/8- began gravimetric analysis determination of unknown; finished that, and then started stoichiometry through 1-butanol question.

Tomorrow, go over gravimetric reverse engineering. go over test ; sig figs.
do Wohler synthesis limited reactant question. Do 4 gas-forming reactions

APB- finished kinematics packet with baseball question; did monkey-hunter question.
Discussed writeup of graphical analysis lab.
Tomorrow - give out review packets; quiz thursday.
Begin Dynamics.
