Identify the potential donor atoms in each of the following Lewis bases and classify the donor atom(s) as hard soft or borderline bases
For the equilibrium H2(g)+ CO2 (g) H20 (g) + CO(g) Kc = 3.18 at 1106K. If each of the four species was initially present at a concentration of 3.000M, calculate the equilibrium concentration of the CO(g) at this temperature
Calculate the concentration of Hg2+, HgCl+, and HgCl2 that result when 1.00 L of a 0.100M Hg(NO3)2 solution is mixed with an equal volume of 0.100M HgCl2 solution.

The following equation represents an oxidation-reduction reaction that uses oxygen. Show how this reaction can also be defined as an oxidation-reduction reaction in terms of electron transfer Pb(s)+02(g) --> PbO(s)
Given that aprotic solvents are not practical for unimolecular processes (little if any reaction occurs via a unimolecular pathway) draw the skeletal structure of the major organic substitution product when (2S,6R)-2,6-dibromo-6-methyloctane is tr..
