Specific Study Points:
Ch 7: precipitation reactions & prediction of solid(s) formed, types of
chemical equations (molecular, complete ionic & net ionic), spectator
ions, describe oxidation-reduction reaction, classifying chemical
reactions, strong vs. weak electrolytes
Ch 8: the mole & Avogadro’s number, calculate grams from moles,
calculate moles from # of atoms/molecules, calculate grams from #
of atoms/molecules, calculate mass percent of element in a
compound
Ch 9: mole-mole relationships in chemical reactions
Ch 14: calculate molar concentration from grams of solute dissolved in
volume of solution, calculate # of atoms/molecules of solute in a
volume of solution
Also: calculation of pH and [H+] in acid solutions
