Fe2O3 isn't a reaction it is Iron(III)oxide a.k.a. hematite or simply rust
no its a single replacement
The reaction is:4 Fe + 3 O2= 2 Fe2O3
The reaction is:2 FeSO4 = Fe2O3 = SO2 + SO3
The thermite reaction usually has two reactants: Iron III oxide (Fe2O3, rust) and aluminum. Both reactants are in powdered form. The reaction equation is: Fe2O3 + 2Al --> Al2O3 + 2Fe The products are aluminum oxide (corundum) and molten iron.
Fe2O3 + 2Al --> Al2O3 + 2Fe molar ratio = 1:2
iron reacts with air to form rust
Pyrite (fools gold) reacts with Oxygen to make Hematite (Fe2O3) and Sulpher dioxide (SO2) The reaction is oxidation of pyrite. 2FeS2 + 3.5O2 - - Fe2O3 + 2SO2
The balanced equation for this reaction is Fe2O3 + 3 H2O = 2 Fe(OH)3.

The reaction is:4 Fe + 3 O2= 2 Fe2O3
The reaction is:2 FeSO4 = Fe2O3 = SO2 + SO3
Fe2O3 + 2Al ===> Al2O3 + 2FeIn this reaction the number of moles of Al2O3 produced is dependent on the number of moles of Fe2O3 and Al that one starts with. For every 1 mole Fe2O3 and 2 moles Al, one gets 1 moles of Al2O3.

combination
Fe2O3 + 3CO -----> 2Fe + 3CO2
That is an oxidation reaction (I am translating the numbers into subscripts) which in this case is also called rusting.
Carbon
2Al + Fe2O3 -> Al2O3 + 2Fe the thermite reaction-
