Explain based on the HSAB concept (“hard and soft acids and bases”) why NaCl is very soluble in water, where as AgCl is not.
Using the 'hard'/'soft' classification of acids and bases, determine whether Keq > 1 or keq < 1 for the following reaction. Briefly explain. Cl3Al-PEt3 + Clzin-NMe3 = Cl3Al-NMe3 + Cl3In-PEt3 For parts (a) and (b), state which of the two solutions has the lower pH: (a) 0.1 M K(NO2)(aq) or 0.1 M K(NO3)(aq) (b) 0.1 M FeCl3(aq) or 0.1 M (FeCl4] (aq)
SHORT ANSWER: 1.) Explain “Hard versus Soft” acid-base behavior. 2.) Explain, in terms of ΔS & ΔG, why imperfections occur in crystals & be able to describe at least two of the four main types of defects, with a drawing of each. 3.) Describe how electron transfer occurs in either the outer sphere or the inner sphere redox reaction mechanism (choose one OR the other). 4.) Explain how to synthesize the cis and trans isomer of a square planar complex,...

Using a partial Lewis dot structure like the one shown above,
draw two more possible structures for the radical cation below and
circle the missing electron.
Fragmentation of Alkanes loss of e wadol C6H14 radical cation = (M+. The scheme above shows the formation of the hexane radical cation from the neutral hexane molecule by bombarding the molecule with high energy electrons which results in the loss of an electron from the molecule. The species that is missing one electron...
