Sentence examples for so2 from inspiring English sources

Another complication arises from the relationship between carbon dioxide (CO2), the principal greenhouse gas (GHG), and sulphur dioxide (SO2), a common pollutant.

Those co-benefits come from reductions in soot that are a by product of sulfur dioxide emissions (SO2) and rest heavily on assumptions as opposed to hard scientific evidence.Since the 1980s, cost-benefit analysis has been progressively integrated into federal rule making by executive orders issued by various presidents.

Many reactions produce a gas such as carbon dioxide, hydrogen sulfide (H2S), ammonia (NH3), or sulfur dioxide (SO2).

One example of an exothermic reaction is the oxidation of iron sulfide (FeS) to form iron oxide (FeO) and sulfur dioxide (SO2) gas: This process gives off large quantities of heat beyond that required to initiate the reaction.

The typical concentration ranges of these gases (in percentage by volume) are as follows: water vapour (H2O) 0 to 7 carbon dioxide (CO2) 0.01 to 0.1 (average about 0.032) ozone (O3) 0 to 0.01 sulfur dioxide (SO2) 0 to 0.0001 nitrogen dioxide (NO2) 0 to 0.000002 Although present in relatively small amounts, these variable constituents may be very important for maintaining life on Earth's surface.

The idea that an acid is a solute that gives rise to cations characteristic of the solvent and that a base is a solute that gives rise to anions characteristic of the solvent has sometimes been extended to solvents where no protons are involved at all for example, liquid sulfur dioxide, SO2.

In this example, the solvent is supposed to ionize according to the equation 2SO2 ⇄ SO2+ + SO32−.

Unlike the feldspars, however, the arrangements of the tetrahedrons differ from species to species, and the interstices may contain water and/or other simple or complex anions such as chlorine (Cl-), carbonate (CO2-/3), or sulfate (SO2-/4), as well as sodium, potassium, and calcium.

Polysulfone, any of a class of resinous organic chemical compounds belonging to the family of polymers in which the main structural chain most commonly consists of benzene rings linked together by sulfonyl (−SO2−), ether (−O−), and isopropylidene (−C CH3 2−) groups.

The species SO2+ and SO32− can certainly be regarded as Lewis acids and bases, but it is doubtful that they exist to any appreciable extent in liquid sulfur dioxide, a situation that makes the discussion somewhat artificial.

Thionyl chloride, regarded as SO2+ + 2Cl−, then can be considered an acid, and potassium sulfite, 2K+ + SO32−, can be considered a base.
