Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V2O5. Commonly known as vanadium pentoxide, it is a brown/yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, it is both an amphoteric oxide and an oxidizing agent. From the industrial perspective, it is the most important compound of vanadium, being principal precursor to alloys of vanadium and is a widely used industrial catalyst.
The mineral form of this compound, shcherbinaite, is extremely rare, almost always found among fumaroles. A mineral trihydrate, V2O5·3H2O, is also known under the name of navajoite.
Upon heating, it reversibly loses oxygen, successively forming V2O4, V2O3, VO and the metal.
Unlike most metal oxides, it dissolves slightly in water to give a pale yellow, acidic solution. When this compound is formed by V2O5 it is an amphoteric oxide. Thus :V2O5 reacts with strong non-reducing acids to form solutions containing the pale yellow salts containing dioxovanadium(V) centers:
Vanadium is the only element which possesses four adjacent oxidation states (+5, +4, +3, +2) that are all stable in aqueous solution. Moreover, they all show very different colors. Starting from yellow V(V) obtained from ammonium metavanadate in acidic solution, all the oxidation states of vanadium can be produced with suitable reducing agents: blue V(IV) with sulfite, dark green V(III) with tin, violet V(II) with zinc amalgam. The sequence of steps from V(V) to V(II) can also be performed in the opposite direction, oxidizing V(II) to V(V) stepwise with cerium(IV) ammonium nitrate: the same sequence of colors in reverse order is displayed.
In this video we'll balance the equation VO2 + O2 = V2O5 and provide the correct coefficients for each compound. To balance VO2 + O2 = V2O5 you'll need to be sure to count all of atoms on each side of the chemical equation. Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Vanadium (IV) oxide + Oxygen gas. Important tips for balancing chemical equations: Only change the numbers in front of compounds (the coefficients). Never change the numbers after atoms (the subscripts). The number of each atom on both sides of the equation must be the same for the equation to be balanced.

Chorus:
Girl I get dat cold sweat
Creepin' up on me
I ache when you shake it
Girl I'm just a freak
Yeah, you set dat cold sweat
Trippin' on me
Burnin' with the fever
Girl you're killing me
Girl you're kinda freaky
Got something 'bout your smile
And when you bounce it up and down
I can't believe my eyes
I got to give you respect
Cos you know how to tease
Keep on walking I'll keep talkin'
You would not believe
Bridge:
What I would do
With a girl like you
Keep your body rockin'
I ain't gonna stop I just want you
And you know
It's shockin' when you rock it
I'm a sick, sick man cos
(Chorus)
Girl I'm just a freak
In need of therapy
I count the ounce in every bounce
And I just want to feast
I love the way you work it
I love the way you grind
Ya got da funk in every pump
If you could read my mind
Bridge
(Chorus)
Down
You're burnin' me down (x3)
I love the way shake now
Love the way you break now
Keep it comin' baby
I don't wanna hesitate now
You got me hooked every look makes me freeze
180 degrees you make me buckle at my knees
Crazy rump shaker sexy move maker
Baby bring it on
Better sooner than later
I feel a cold sweat creepin' up on me
We gotta get it on
Tell me what it's gonna be
(Bridge)
(Chorus until fade)
