What is the electron configuration for Bromine?
Draw the two resonance structures of ozone, O3.
Write what type of hybridization each carbon has. Draw
the electron cloud for each bond of this molecule.
Draw a corrected version of this molecule, including
formal charges.
Vinegar and sodium hydroxide react. Show the reaction,
the transfer of electrons using arrows, label the
conjugate acid and conjugate bases, and predict the
direction of the reaction using the pKa’s. The pKa of
acetic acid is 4.75 and the pKa of water is 15.7.
