Question

Iron oxide reacts with aluminum to give aluminum oxide and iron. What kind of chemical reaction is this?

Answer 1

The chemical equation would look something like this... (keep in mind the subscripts are not there, because we can't find them with the given data)
FeO + Al -> AlO + Fe
In this case it is a SINGLE REPLACEMENT ReactionThis is because the Iron and Aluminum swapped places (were replaced). Only one replacement occurred... so that's where the single part of it comes from.
