Chromium(III) oxide is amphoteric. Although insoluble in water, it reacts with acid to produce salts of hydrated chromium ions such as [Cr(H 2O) 6] . It is also attacked by concentrated alkali to yield salts of [Cr(OH) 6] . When heated with finely divided carbon or aluminium, it is reduced to chromium metal: Cr 2O 3 + 2 Al → 2 Cr + Al 2O 3 WebDichromium trioxide when heated with finely divided aluminium or carbon reduces to chromium metal.

Explain, in terms of structure and bonding, why sulfur trioxide has a higher melting point than sulfur dioxide. Sulfur trioxide is a larger molecule than sulfur dioxide so the van der Waals' forces between the molecules are stronger. greenville sc at christmas
