Different reactions require different conditions. Sometimes conc. H2SO4 just screws up the reactants and sometimes diluted H2SO4 is just not enough or the reaction needs absence of water

What is your knowledge on chemistry, and above all, on experimental chemistry? I know a few, but it depends on your knowledge levels that you could perform them safely or not. The first one that comes to my mind is exploring the Pourbaix diagram of Aluminum...

It is more complicated than that, electrons are not placed in "concrete spots" of the molecules, you can say that they are in a given molecular orbital. But for sake of simplification, you can say that in that hypothetical situation, the electron could be on the central atom and you would have...

NH4 will not exist. If an NH3 molecule binds to another atom/molecule, a positive charge will be held by the nitrogen.

Just imagine that the lone pair that is necesary to form hydrogen bonding which is present on NH3, it is not present on NH4+, becasue "it's forming the bond with the fourth hydrogen".

This is pretty much it. For a molecule to absorb light of a given wavelenght, there must be two molecular orbitals (one filled and one with room for an electron) between which an electronic transition is allowed. The energy difference between these two orbitals, equals the energy of the light...
