Mar 22, 2015 · The electronic configuration of Fe is $\ce { [Ar] 3d^6 4s^2}$. So after removing two electrons the configuration becomes: $\ce { [Ar] 3d^6}$ But why can't the electrons rearrange …

Dec 9, 2015 · I would like to know the differences between Fe3+ and Fe2+ ions. I'm guessing they must differ in reactivity but I'm not sure how. Also, is there a way that we can observed the differences

Aug 27, 2017 · 15 Diiron nonacarbonyl, $\ce { [Fe2 (CO)9]}$, is often depicted with an Fe–Fe bond as shown at the left-hand side: The Fe—Fe bond is usually invoked in order to (1) explain the observed …

Sep 11, 2015 · Can you please help me understand if I got the half reactions correct? $$\ce {KMnO4 + FeSO4 + H2SO4 -> K2SO4 + MnSO4 + Fe2 (SO4)3 + H2O}$$ I found out that manganese is …

Dec 12, 2024 · I'm taking a chemistry course right now. I've learned about electron configuration and ionization and wondered why iron doesn't "like" ionizing to a 1+ state. When iron goes to …

Dec 12, 2016 · It is not clear what do you mean stable. Iron (III) salts generally form an oxo-hydroxo precipitate unless some complexation or other tricks going on. From that point of view, it doesn't …

Aug 23, 2023 · Fe3+ has 23 electrons and Fe2+ has 24electrons. When electrons are accommodated in d orbitals, up to five orbitals are empty, so electrons are placed into separate orbitals one by one …

May 15, 2018 · It is said that $\ce {Fe^2+}$ can bind oxygen while $\ce {Fe^3+}$ cannot. Why is that so? $\ce {Fe^3+}$ has an extra electron, it could bind more easily to the oxygen. And how and why does …

Nov 8, 2021 · Can Fe2+ ions exist in an acidic solution or will they always pick up available protons and become Fe3+? My hunch is they can't exist but I'm not really sure. If the latter, does that mean that

Sep 16, 2015 · Not in igneous rocks. Most iron there, in silicate minerals throughout the deep crust and mantle, is Fe (II). Need to weather the rocks and expose the iron to an oxidizing atmosphere to get …
