Hey again. Another question ive stumbled upon is this. Just wanted to check that its right/ how I can improve this.



Its regarding the electron transfer that take place in reactions 4-5 and 5-6

I know that the Fe electron config for 4 is [Ar] 3d6 4s2

                      Fe4+ in 5 is                   [Ar] 3d4

                      Fe3+ in 6 is                   [Ar] 3d5
                       
                      O in 4 is                        [He] 2s2 2p4

                      O in 5 is                        [He] 2s2

                      O in 6 is                        [He] 2s1

ie from reaction 4 to 5 Fe has been Oxidised and Oxygen has been reduced. Electrons have been transferred from the oxygen to the iron in the formation of the Fe=O bond.

In reaction 5 to 6 Iron has been Reduced and Oxygen has been oxidised.
