Vedclass · Answer

(C) Let the oxidation number of $Fe$ be $x$.In $Fe_3O_4$,the oxidation number of $O$ is $-2$.Applying the rule for the sum of oxidation numbers in a neutral molecule:$3(x) + 4(-2) = 0$$3x - 8 = 0$$3x = 8$$x = \frac{8}{3}$Thus,the average oxidation number of $Fe$ in $Fe_3O_4$ is $\frac{8}{3}$.Actually,$Fe_3O_4$ is a mixed oxide of $FeO$ and $Fe_2O_3$,where $Fe$ exhibits oxidation states of $+2$ (in $FeO$) and $+3$ (in $Fe_2O_3$).
