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 …

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 …

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

Oct 15, 2019 · Why does Fe(III) form octahedral coordination complexes if it has 5 electrons in its d-orbitals? I understand that Fe(II) has 6 electrons in its d-orbitals and 6 lone pairs from 6 ligands as …

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 …

Aug 8, 2015 · Iron(II) sulfate (ferrous sulfate) is a salt that, in an aqueous solution, dissolves and yields $\\ce{Fe^{2+}(aq)}$ and $\\ce{SO4^{2-}(aq)}$. It then decomposes to ferric sulfate shortly thereafter. ...

Mar 6, 2017 · How would one use the equation ΔG° = −nFE° to estimate the ΔG⁰f of Fe2+(aq)? Since Fe2+ appears in multiple entries in the following table, I'm not sure which value to use.

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 …

Sep 16, 2021 · I need to prepare a solution of Ferrous Iron (Fe2+). This solution will be used to test a water filtration system by simulating the Ferrous Iron that is sometimes present in well water.
