Because the response factors for sulfur and oxygen are largely independent of the type of compound, calibration and determination of total element content are simplified. The use of a 0.1 mm i.d. capillary colum

sulfur oxide, any of several compounds of sulfur and oxygen, the most important of which are sulfur dioxide (SO2) and sulfur trioxide (SO3), both of which are manufactured in huge quantities in intermediate steps of sulfuric acid manufacture. The dioxide is the acid anhydride (a compound ...
The common organic sulfur compounds are analogous to organic oxygen compounds: RSH, thiols; RSR, sulfides and RSSR, disulfides. The names and structures of the organic sulfur compounds known to be involved in atmospheric sulfur chemistry are listed in Figure 1. With the exception of hydroxy...
Does sulfur replace oxygen in the superconducting YBa 2 Cu 3 O 6 S phase?doi:10.1016/0038-1098(88)90766-1Electron microscopy studies indicate a sulfur containing phase of approximate composition YBa2Cu3O6S in "fresh" samples. This compound is superconducting and its Tc is 91 K. Its phase ...
Sulfur dioxide(二氧化硫)is an important compound in its own right。It is used in the manufacture of paper。When made from wood pulp or from other materials,paper is usually pale yellow in colour。 Sulfur dioxide is used to bleach(漂白)it to the white colour which is needed。Sulfur dioxide ...

Sulfur forms two oxides, sulfur dioxide, SO2, and the trioxide, SO3. It burns in oxygen at about 250°C or in air above 260°C, forming sulfur dioxide. In excess oxygen the trioxide is obtained. Sulfur reacts with hydrogen at 260 to 350°C forming hydrogen sulfide. The reaction is sl...
What is the empirical formula for a compound containing 80.68% mercury, 12.87% oxygen, and 6.45 % sulfur? Answer and Explanation: Start by determining the amount of each element in 100 g of the substance, which gives you 80.68 g Hg, 12.87 g O, 6.45 g S...
The presence of oxygen during adsorption leads to the formation of NO2, which remains on the adsorbent, whereas NO does not. This technique is also well suited for gases like NH3 and H2S. Two heterotrophic bacteria, Paracoccus denitrificans and Pseudomonas denitrificans, have also been found in ...
