Question

The reaction of aluminum and iron (III) oxide to form iron and aluminum oxide

Answer 1

Fe₂O_{3(s) +} 2Al_(s) -----> 2Fe(s) +  Al₂O_3(s)

The magnesium ribbon ignites the thermite starter mixture, which in turn ignites the thermite mixture. In an extremely exothermic reaction, the aluminum reduces the iron in the ferric oxide.
