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]
From left: [V(H 2 O) 6] 2+ (lilac), [V(H 2 O) 6] 3+ (green), [VO(H 2 O) 5] 2+ (blue) and [VO(H 2 O) 5] 3+ (yellow).. Vanadium compounds are compounds formed by the element vanadium (V). The chemistry of vanadium is noteworthy for the accessibility of the four adjacent oxidation states 2–5, whereas the chemistry of the other group 5 elements, niobium and tantalum, are somewhat more limited to ...
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

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]
The song took center stage at the 2024 Paris Olympics when a DJ played it to ease tensions between Brazil and Canada's respective teams at the women's beach volleyball final on Aug. 9.
VO is a non-stoichiometric compound, its composition varying from VO 0.8 to VO 1.3. [2] Diatomic VO is one of the molecules found in the spectrum of relatively cool M-type stars. [3] A potential use of vanadium(II) monoxide is as a molecular vapor in synthetic chemical reagents in low-temperature matrices. [4]
