the reaction of iron metal with oxygen to form iron (iii) oxide?
electrolytic process
when an oxygen absorber is removed from its protective packaging, the moisture in the surrounding atmosphere begins to permeate into the iron particles inside of the absorber sachet. moisture activates the iron, and it oxidizes to form iron oxide. typically, there must be at least 65% relative humidity in the surrounding atmosphere before the rusting process can begin. to assist in the process of oxidation, sodium chloride is added to the mixture, acting as a catalyst or activator, causing the iron powder to be able to oxidize even with relatively low humidity. as oxygen is consumed to form iron oxide the level of oxygen in the surrounding atmosphere is reduced. absorber technology of this type may reduce the oxygen level in the surrounding atmosphere to below 0.01%. complete oxidation of 1 g of iron can remove 300 cm of oxygen in standard conditions. though other technologies can remove more, iron is the most useful as it does not cause odor like sulfur compounds or passivate like aluminium compounds. many other alternatives are not food safe. the moisture requirement of iron-based scavengers makes them ineffective in moisture sensitive applications.

in the second, the planet accretes from both water-rich and iron metal-rich material. however, the metal iron reacts with water to form iron oxide and release hydrogen before differentiation of a metal core has taken place. provided the iron droplets are well mixed and small enough (1 centimeter), the predicted end result is that the iron is oxidized and trapped in the mantle, unable to form a core.
