    en.wikipedia.org/wiki/Aluminium(II)_oxide

    Aluminium(II) oxide or aluminium monoxide is a compound of aluminium and oxygen with the chemical formula AlO. It has been detected in the gas phase after explosion of aluminized grenades in the upper atmosphere [ 1 ] [ 2 ] [ 3 ] and in stellar absorption spectra.

    Fe 2 O 3 + 2 Al → Al 2 O 3 + 2 Fe. This equation shows that 1 mole of iron(III) oxide and 2 moles of aluminum will produce 1 mole of aluminium oxide and 2 moles of iron. So, to completely react with 85.0 g of iron(III) oxide (0.532 mol), 28.7 g (1.06 mol) of aluminium are needed.

  6. Aluminium oxide - Wikipedia

    en.wikipedia.org/wiki/Aluminium_oxide

    Al 2 O 3 is an electrical insulator but has a relatively high thermal conductivity (30 Wm −1 K −1) [2] for a ceramic material. Aluminium oxide is insoluble in water. In its most commonly occurring crystalline form, called corundum or α-aluminium oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting ...

    They are typically designated as having an atomicity of 2. The atomicity of homonuclear molecule can be derived by dividing the molecular weight by the atomic weight. For example, the molecular weight of oxygen is 31.999, [ 3 ] while its atomic weight is 15.879; [ 4 ] therefore, its atomicity is approximately 2 (31.999/15.879 ≈ 2).
