A galvanic cell consists of an Ag(s)/Ag(aq) half cell and a Zn(s)/Zn2+ half-cell connected by a salt bridge. Write the two half cell reactions...if you could look up the standard reduction potentials too, that would be awesome! will rate 5 stars.
which is connected to 2 oxygen atoms, one with is sp^3 and one sp^2 hybridized and so both oxygens have 2 lone pairs of electrons. All other single bonds consist of hydrogen.
