Basic gallium sulfate is known with the formula (H 3 O)Ga 3 (SO 4) 2 (OH) 6. [6] Double gallium sulfates are known with composition NaGa 3 (SO 4) 2 (OH) 6, KGa 3 (SO 4) 2 (OH) 6, RbGa 3 (SO 4) 2 (OH) 6, NH 4 Ga 3 (SO 4) 2 (OH) 6. These compounds are isostructural with jarosite and alunite. Jarosite and alunite can contain a small amount of ...
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 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]
In mathematics, the indefinite orthogonal group, O(p, q) is the Lie group of all linear transformations of an n-dimensional real vector space that leave invariant a nondegenerate, symmetric bilinear form of signature (p, q), where n = p + q.
Nguyễn Ngọc Trường Sơn (born 23 February 1990) is a Vietnamese chess player. The second-best player in Vietnam, he is the youngest Vietnamese ever to become a Grandmaster, [1] and one of the youngest grandmasters in the history of the game, having qualified for the title at the age of fourteen.
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).
Sodium oxalate starts to decompose above 290 °C into sodium carbonate and carbon monoxide: [2]. Na 2 C 2 O 4 → Na 2 CO 3 + CO. When heated at between 200 and 525°C with vanadium pentoxide in a 1:2 molar ratio, the above reaction is suppressed, yielding instead a sodium vanadium oxibronze with release of carbon dioxide [6]
