This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. ... 16 S sulfur (orthorhombic ...
Sulfur trioxide, SO 3, a chemical compound of sulfur and the anhydride of sulfuric acid; Sulfite, SO 2− 3, a chemical ion composed of sulfur and oxygen with a 2− charge; SO(3), the special orthogonal group in 3 dimensions; the rotations that can be given an object in 3-space; Star Ocean: Till the End of Time, the third main game in the Star ...
Oleum (Latin oleum, meaning oil), or fuming sulfuric acid, is a term referring to solutions of various compositions of sulfur trioxide in sulfuric acid, or sometimes more specifically to disulfuric acid (also known as pyrosulfuric acid). [1] Oleums can be described by the formula ySO 3 ·H 2 O where y is the
Boiling point: −10 °C (14 °F; 263 K) Solubility in water. ... is being used. The product is sulfur dioxide (SO 2) with some traces of sulfur trioxide (SO 3). The ...
Vanadium(V) oxide serves the crucial purpose of catalysing the mildly exothermic oxidation of sulfur dioxide to sulfur trioxide by air in the contact process: 2 SO 2 + O 2 ⇌ 2 SO 3. The discovery of this simple reaction, for which V 2 O 5 is the most effective catalyst, allowed sulfuric acid to become the cheap commodity chemical it is today.
With a boiling point of −144.75 °C, OF 2 is the most volatile ... It can oxidize sulphur dioxide to sulfur trioxide and elemental fluorine: OF 2 + SO 2 → SO 3 + F 2.
Unlike the classic thermite reaction involving iron oxides, the chromium oxide thermite creates few or no sparks, smoke or sound, but glows brightly. Because of the very high melting point of chromium, chromium thermite casting is impractical. Heating with chlorine and carbon yields chromium(III) chloride and carbon monoxide: Cr 2 O 3 + 3 Cl
