WebSome metals corrode when they react with air. Metals are excellent heat and electricity conductors. Metals are usually in a solid state at room temperature. Metals’ chemical properties are usually high in density. Metals are malleable and ductile, as well as malleable. Metals, like other or non-metallic metals, form an alloy. 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 ...
