Q. Show the chemical properties of Aluminium?

Aluminium has a very high affinity for oxygen; this is reflected in high exothermic heat of formation of Al₂0₃ (-1676 kJ mol^-1). This allows aluminium to extract  oxygen from other metal oxides, and forms the basis of Goldschmidt's  aluminothermic process for Ca, Sr, Ba, Mn, Cr, Mo, etc:

3Mn0₂ + 4Al --------------------------------->+ 2AI₂, 03 + 3Mn

Fe₂0₃ + 2Al --------------------------------->Al₂, O3, + 2Fe (l)
