If you can't helium, and you can't curium, then you might as well barium.

Re: Calculating Work under constant pressure
but if pressure is constant, then P is constant and you can take P out of the integral tonmake w= -P(V_f - V_i) = -P[delta]V

naming coordination compounds
I understand that when naming a compound, if the net charge is negative, the transition metal ends in -ate. However, if say a sodium was attached to the compound would the transition metal's name still end in -ate? If so, why?

Identifying oxides as acidic, basic, amphoteric (12.17)
In chapter 12 question 17 the question states:
States whether the following oxides are acidic, basic, or amphoteric: (a) BaO (b) SO_3 (c) As_2O_3 (d) Bi_2O_3
How are you suppose to determine whether it is acidic, basic, or amphoteric?

All the ligands will be in the coordination sphere but not all the compounds have to be octahedral.

Re: Removing 2nd Electron
Removing a second electron is harder than the first because a net positive charge has already been created. Therefore, the second electron you are trying to remove is being my tightly held by the atom due to the fact that there are more protons and electrons.
