WebSep 16, 2024 · In Equation 4.4.3, for example, the total number of electrons lost by aluminum is equal to the total number gained by oxygen: electrons lost = 4 Al atoms × 3 e − lost Al atom = 12 e − lost. electrons gained = 6 O atoms × 2 e − gained O atom = 12 e − gained. The same pattern is seen in all oxidation–reduction reactions: the number of ... WebThe equation for this reaction is: 2 Al(s) + Fe 2 O 3 (s) --> 2Fe (s) + Al 2 O 3 (s). The large decrease in the energy of the system is a consequence of the high charge concentration on the aluminum ion due to its small size. The oxide ions can approach the aluminum ion more closely than than they can approach the ferric ion.
