Predict whether a precipitate will form when the following aqueous solutions are mixed. If a precipitate will form, write out (i) the formula of the precipitate and (ii) a net ionic equation that describes its formation. To make your predictions, use the solubility table handed out with the lecture notes (or the solubility rules given in your textbook). Finally, when writing out net ionic equations, don't forget to include state symbols! CaCl2(aq) + K3PO4(aq) rightarrow KCl(aq) + Na2SO4(aq) rightarrow (NH4)2CO3(aq) + Ba(NO3)2 rightarrow NaC2H3O2(aq) + SbCl3(aq) rightarrow Pb(NO3)2(aq) + K2SO4(aq) rightarrow

Show the mechanism, and draw a likely major product of the following reaction including regiochemistry H20 H2SO4 Ym@성 O.

The molecular orbital (MO) diagram below is for a typical diatomic molecule or ion (namely, the diagram applicable to O_2 and F_2 or perhaps OF-forms) for valence electrons only. Label each atomic and molecular orbital with designation (for example: sigma_1s) and draw a picture of each orbital. Fill the valence electrons of O_2 molecule into the above diagram. Write the electron configuration for the O_2 molecule that includes (i) only the valence electron, and (ii) all electrons. How is the MO diagram above different from the one for diatomic molecules/ion with a large 2s-2p interaction? Consult your textbook/lecture notes if necessary.
