what happens to an iron atom as soon as it leaves its ore?

year 9 homework,step by step guide needed.thanks.

The tire seals to the rim and keeps air in. Almost all cars have tubless tires.i think only things like lawnmowers and bikes use tires with tubes

the summary: it rusts.

Becomes charged. I think.

I think it starts to oxidize, react with oxygen in air to form Fe2O3 4Fe(s) + 3O2(g) -- 2Fe2O3(s) Solid iron with a charge of 0 reacts with diatomic (molecular) oxygen also with a charge of 0 oxygen is an oxidizer, it takes electrons away from another element which is a reducing agent, (it gives electrons to another element) iron is a reducer, it will donate it's electrons. oxygen goes from O2 + 2e -- O^2- (reduction) iron goes from Fe -- Fe^2+ + 2e (oxidation) put the two equations together and you get: O2 + 2e + Fe -- O^2- + Fe^2+ + 2e cancel out the 2e on each side: O2 + Fe -- O^2- + Fe^2+ balanced: 3O2 + 4Fe -- 6O^2- + 4Fe^2+ (complete balanced oxidation/reduction equation showing how each element gains or loses electrons) the other equation is called the balanced molecular equation, it doesn't show how electrons are gained or lost: 4Fe(s) + 3O2(g) -- 2Fe2O3(s)
