  3. Diagrams, Graphs, Charts, and other Images Summaries


Suggested sub-topics to pay particular attention to:

  • pKa = pH at half equivalence point

  • comparison of intermolecular forces that are not obvious (when London Dispersion Forces are stronger than dipole)

  • skeletal Lewis electron-dot diagrams that require electrons added

  • Coulomb’s Law descriptions and comparisons

  • half-life for 1st order reactions

  • photoelectron spectra

  • glassware needed for various labs (usually acid/base labs)

  • particle diagrams

  • graphical analysis

  • lab error analysis
