Vanadium(III) oxide is the inorganic compound with the formula V 2 O 3.It is a black solid prepared by reduction of V 2 O 5 with hydrogen or carbon monoxide. [3] [4] It is a basic oxide dissolving in acids to give solutions of vanadium (III) complexes. [4]
Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Aluminium oxide (Al 2 O 3) is an example of an amphoteric oxide. Amphoterism depends on the oxidation states of the oxide. Amphoteric oxides include lead(II) oxide and zinc oxide, among many others. [5]

Most often used in court volleyball by the setter, it is often called a "setter dump" or a "turn and burn", but on the beach it is colloquially referred to as an "on-two" One-Two-Two Coverage: Attack coverage system where one player covers directly under the block, two players cover 1–3 meters away, and two players cover 4–5 meters away
These solutions contain mainly the ions HVO 4 2− and V 2 O 7 4− between pH 9 and pH 13, but below pH 9 more exotic species such as V 4 O 12 4− and HV 10 O 28 5− (decavanadate) predominate. Upon treatment with thionyl chloride, it converts to the volatile liquid vanadium oxychloride, VOCl 3: [11] V 2 O 5 + 3 SOCl 2 → 2 VOCl 3 + 3 SO 2
The Beach Volleyball Database, also known as BVB Info, [1] is a website that tracks international beach volleyball players, tournaments and history, including results of North American and international tournaments. [2] It is the only website of its kind in the sport of beach volleyball. [citation needed]

Snow volleyball is a variant of beach volleyball that is played on snow. The rules are similar to the beach game, [1] with the main differences being the scoring system (best of 3 sets played to 15 points) and the number of players (three starters and one substitute). [2]
