A. The correct Lewis
structure has 1 nitrogen oxygen single bond, one nitrogen oxygen
and a lone pair on the nitrogen. It exhibits resonance.
B. The correct Lewis
structure has 1 nitrogen oxygen single bond, one nitrogen oxygen
and a lone pair on the nitrogen. It does not exhibits
resonance.
C. The correct Lewis
structure has 2 nitrogen oxygen single bonds and 2 lone pair on the
nitrogen. It does not exhibits resonance.

Draw the complete Lewis structure (including lone pairs of
electrons) for the anion that is formed after acetic acid has lost
its acidic hydrogen. Can you draw more than one structure? What do
you call it when more than one Lewis Structure is possible for an
ion or a molecule

Choose 2 (TWO) of the following PAIRS of terms related
to PLANTS to compare and contrast (this means that you
need to explain both shared features and distinguishing features in
the pair). You also need to include at least ONE specific phylum
for each term.
For example: microgametophyte and
megagametophyte: These terms refer to organisms found in
the 4 phyla of the the Gymnosperms and the Anthophyta in the plant
Kingdom. The microgametophyte is contained within the pollen grain
and...
