Day 12

A: did reverse engineer gravimetric analysis problem

and then limiting reactant with molarity...into ideal gas law calculation

forgot to do adding excess acid with a back titration...put that on the NEXT test as well as an empirical formula problem with 4 or more elements....

started Boyle's Law....do NOT belabor the laws...just ask for explanation according to kinetic molecular theory!

D: plan to do atomic mass calculations and then to start atomic theory:

democritus...dalton...thomson....rutherford...

actually did atomic mass from % abundance for two and three isotope examples... Cl and Si
did reverse for a two isotope example for P

for G, actually find and use real examples from webelements!

E: did atomic number, mass number, model of an atom and its isotopes, cation, anion, notation and charts.

did #p - #e = charge on ion
