what is the Born-haber cycle? and can you show how it describes the formation CaF2.
Note: stands in for other symbols. PLEASE SEE ATTACHMENT FOR PROPER FORMULA SYMBOLS. Given the following data: Gf Ca2+(aq) = -553 kJ / mol Gf Cl-(aq) = -131 kJ / mol Gf CaCl2(s) = - 748 kJ / mol Ghyd Ca2+(g) = -1517 kJ / mol Ghy ...continues
my professor gave us this and told us that some of these problems will be on our test. So I just want to make sure I know how to do all of them correctly. Thanks :-o
these are suggested problems in our book for our test
A sample of 27.0 mL of 0.310 Molarity NaOH is titrated with 0.740 Molarity H2SO4. How many milliliters of the H2SO4 solution are required to reach the end point? The book gives the answer of 5.66mL but doesn't show the work. I need to see the procedure for solving this problem.
Ionization Energy (I.E.) generally increases across a period from left to right. However, the I.E. of aluminum does not follow this trend and is lower than that of magnesium. Using the valence shell electronic configuration of Mg and Al, explain why this exception occurs. Clearly justify your answer.
Electron affinity (E.A.) generally becomes more negative across a period, from left to right. However, the E.A. of phosphorus does not follow this trend and is less negative than that of silicon. Using orbital diagrams showing the valence electronic configuration of Si and P, explain why this exception occurs. Clearly justify yo ...continues

[Co(h20)6]3+ will oxidize water [Co(Nh36]3+ is stable in aqueous solution How is this possible? Both are mondentate ligands. I thought the proximity of the nitrogens after one has bonded to the cobalt would make it more likely to react, because the entropy would be lowered.They are also both low spin complexes

Why do square planar geometries occur in d7, d8, and d9 ions with strong field- pi acceptor ligands, except in cases in which ligand geometry requires it?
