Sometimes chemical reactions between two or more substances give off or take in … WebThe reaction is: iron (III) oxide + aluminium → aluminium oxide + iron. This shows that aluminium is above iron in the reactivity series. Once underway, the reaction is highly exothermic, rapidly reaching temperatures as high as 2000 °C, well in excess of the melting point of iron (1535 °C). The practical use of this reaction is to weld ...
