places the question in its scientific context
gives the minimum necessary background
Test #1 Topics
20 multiple choice (30 minutes, NO CALCULATOR)
24 marks written (40 minutes, calculator permitted)
Electronegativity, atomic radius, ionic radius trends on the periodic table
Electron configuration f
transition metals have a tendency to form
usually consist of a complex ion and a
natural examples include: heme, chlorophyll,
a central metal ion
Factors that Affect Reaction Rates
of the reactant increased
contact increases the rate of the reaction ie.
dissolving, gases, liquids
greater probability of
contact at higher concentrations
H from Bond Energies
the enthalpy change for a chemical reaction
can be determined using the difference
between the energies required to break
reactant bonds and the energies released
when product bonds form
H = nEbonds broken nEbonds forme
