Aluminium oxide (or aluminium(III) oxide) is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3. It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium oxide. It is commonly called alumina and may also be called aloxide, aloxite, or alundum in various forms and ...
Aluminium(I) oxide is formed by heating Al and Al 2 O 3 in a vacuum while in the presence of SiO 2 and C, and only by condensing the products. [2] Information is not commonly available on this compound; it is unstable, has complex high-temperature spectra, and is difficult to detect and identify. In reduction, Al 2 O is a major component of ...
A stable derivative of aluminium monoiodide is the cyclic adduct formed with triethylamine, Al 4 I 4 (NEt 3) 4. Also of theoretical interest but only of fleeting existence are Al 2 O and Al 2 S. Al 2 O is made by heating the normal oxide, Al 2 O 3, with silicon at 1,800 °C (3,272 °F) in a vacuum. Such materials quickly disproportionate to the ...
There is a 1:1 molar ratio of NH 3 to NO 2 in the above balanced combustion reaction, so 5.871 mol of NO 2 will be formed. We will employ the ideal gas law to solve for the volume at 0 °C (273.15 K) and 1 atmosphere using the gas law constant of R = 0.08206 L·atm·K −1 ·mol −1 :

A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.

The anhydrous phase cannot be regained on heating the hexahydrate. Instead HCl is lost leaving aluminium hydroxide or alumina (aluminium oxide): [Al(H 2 O) 6]Cl 3 → Al(OH) 3 + 3 HCl + 3 H 2 O. Like metal aquo complexes, aqueous AlCl 3 is acidic owing to the ionization of the aquo ligands: [Al(H 2 O) 6] 3+ ⇌ [Al(OH)(H 2 O) 5] 2+ + H +
