need the answer for my science homework, can‘t find it anywhereplease help?
The issue is how tenaciously aluminum bonds to the oxygen. Aluminum (and Titanium as well) is very difficult to separate from it's oxide. You must use an electric arc furnace operating in either a vacuum or an inert atmosphere (like argon) in order to get aluminum to give up it's oxygen. Iron oxide on the other hand can be refined in a simple furnace. All it takes is heat and a flux (limestone).
The first two answers are 100% Wrong! They've used the wrong numbers in the equations. Now you said Iron Oxide.which? There could be Iron (II) Oxide - FeO or Iron (III) Oxide - Fe2O3 (this is Rust and is red-brown) Since Fe2O3 is rust, im guessing you are looking at FeO. So, for Iron (II) Oxide - FeO 2Al + 3FeO --- Al2O3 + 3Fe For Iron (III) Oxide - Fe2O3 2Al + Fe2O3 --- Al2O3 + 2Fe All numbers behind elements are in small.
