H 2 S 2 O 5 +5 (of the sulfur atom bonded to 3 oxygen atoms), +3 (of other sulfur atom) Disulfite commonly known as metabisulfite, S 2 O 2− 5: Not known. Sulfurous acid: H 2 SO 3 +4 Bisulfite, HSO − 3 and sulfite, SO 2− 3: Not known. Dithionous acid: H 2 S 2 O 4 +3 Dithionite, O 2 SSO 2− 2: Not known. Sulfoxylic acid: H 2 SO 2 +2 ...
The compound is prepared by treating V 2 O 5 in sulfuric acid with elemental sulfur: [2] V 2 O 5 + S + 3 H 2 SO 4 → V 2 (SO 4) 3 + SO 2 + 3 H 2 O. This transformation is a rare example of a reduction by elemental sulfur. When heated in vacuum at or slightly below 410 °C, it decomposes into vanadyl sulfate (VOSO 4) and SO 2. Vanadium(III ...
The universal cover of SO(3) is a Lie group called Spin(3). The group Spin(3) is isomorphic to the special unitary group SU(2); it is also diffeomorphic to the unit 3-sphere S 3 and can be understood as the group of unit quaternions (i.e. those with absolute value 1).
The group SO(3) can therefore be identified with the group of these matrices under matrix multiplication. These matrices are known as "special orthogonal matrices", explaining the notation SO(3). The group SO(3) is used to describe the possible rotational symmetries of an object, as well as the possible orientations of an object in space.
Sulfuric(IV) acid (United Kingdom spelling: sulphuric(IV) acid), also known as sulfurous (UK: sulphurous) acid and thionic acid, [citation needed] is the chemical compound with the formula H 2 SO 3. Raman spectra of solutions of sulfur dioxide in water show only signals due to the SO 2 molecule and the bisulfite ion, HSO − 3. [2]
When conducted in warm water, Na 2 SO 3 initially precipitates as a white solid. With more SO 2, the solid dissolves to give the disulfite, which crystallizes upon cooling. [2] SO 2 + 2 NaOH → Na 2 SO 3 + H 2 O. Sodium sulfite is made industrially by treating sulfur dioxide with a solution of sodium carbonate. [3] The overall reaction is:
L n M−OH + CO 2 ⇌ L n MO−O−CO 2 H. The oxygen evolving complex (OEC) consists of a Mn-Ca-O-OH cluster that is responsible for the biosynthesis of O 2. It is proposed that the O-O bond forming step involves a hydroxide ligand. Metalloproteinases catalyze the hydrolysis peptide bond. The catalytic center is such enzymes often involves ...
There are several general reasons for this: (1) they may condense to form oligomers (e.g., H 2 CrO 4 to H 2 Cr 2 O 7), or dehydrate all the way to form the anhydride (e.g., H 2 CO 3 to CO 2), (2) they may disproportionate to one compound of higher and another of lower oxidation state (e.g., HClO 2 to HClO and HClO 3), or (3) they might exist ...
