Exothermic Iron-Oxide and Aluminum Reaction
Uploaded by: FreeScienceLectures
Video Description:
http://www.FreeScienceLectures.com
A metal crucible is filled with iron-oxide and aluminum. A small amount of potassium, sugar and chloride is placed on top of iron-oxide aluminum mixture. A few drops of concentrated sulphuric acide is added to the mixture to start the reaction. The reaction extremely exothermic. The crucible becomes red hot. The aluminum has reduced the iron-oxide to iron.

Tell a friend:
Fe2O3 + Al --> Al2O3 + Fe
Al2O3 is Aluminium Oxide. So the thermire reaction produces iron and aluminium oxide.
You've got:
-Fe2 in the beginning but end up with 1 Fe
-1 Al in the beginning and eng up with 2Al
if the beginning is correct then I think you should end up like this:
Fe2 O3 + Al -> Al O3 + 2Fe
But I presume you messed up the base:
Fe2 O3 + Al2 -> Al2 O3 + 2Fe
Let me know if I'm wrong.
Checked with chem professor. You have to remember to switch the valencies during this ionic reaction. Al2O3 is released as fine particles into the atmosphere (during thermite reaction)
