Want this question answered?
One is oxidized aluminum and the other is oxidized iron. Iron oxide is magnetic. Aluminum oxide is not. Most of the clear semi precious gems like rubies and emeralds are made from aluminum oxide. Iron oxide is in hematite the black, opaque mineral.
aluminum
You can react Aluminum to react with Ironoxide to get Iron. Iron(II)oxide + Aluminum --> Aluminumoxide + Iron Fe2O3 + 2Al --> Al2O3 + 2Fe
Yes, the best mixture (cost effectively and fairly good burn) is Aluminum-oxide and Black iron oxide
It will form a mixture of the two compounds.
2Al + Fe2O3 -> Al2O3 + 2Fe the thermite reaction-
For the classical iron oxide and aluminum thermite, the products of the reaction are aluminum oxide (Al2O3) and iron (Fe). However, there are many kinds of thermite, but they always produce the pure metal from the oxide.
This reaction is:Al + Fe2O3 = Al2O3 + Fe
Yes. In fact, aluminum oxidizes faster than almost any other metal, which is why aluminum foil will, actually, remove rust: The abrasion removes the coating of aluminum oxide that covers all metallic aluminum exposed to the air, and the exposed aluminum metal wants to be oxidized so badly that it will actually steal oxygen from iron oxide, AKA rust, and reduce it back to iron metal. Which is why aluminum foil will, in fact, remove rust. This reaction, interestingly, is the same one that makes thermite work.
Yes, it is correct. A thermite reaction.
Rust is Iron oxide, so no.
Both iron and aluminum will oxidize. When iron oxidizes the product (rust) easily crumbles away, exposing more iron to oxidation. Aluminum is even more reactive than iron, but the aluminum oxide that forms is one of the hardest known substances and forms a protective layer that, even though it is microscopic, shields the aluminum from corrosion.
