Which one of the following is expected to be the strongest Lewis acid? Fe, Fe+, Fe2+, Fe3+ Which do you think would accept electrons the easier? Fe(s) or Fe^+? Do that same kind of logic on the others one by one.
If an equal number of moles of the weak acid HOCN and the strong base KOH are added to water, the resulting solution will be acidic, basic or neutral? There is a complicated answer and a sensible answer. Both arrive at the same answer. But here is the logic for the sensible--I...
