where [k.sub.tri] and [k.sub.trj] are the monatomic values of thermal conductivity of components i and j, respectively [dimensionless], and M[W.sub.i] and M[W.sub.j] are the molecular weight of components i and j, respectively [kg/kmol].
The element iodine exists in nature under several forms: inorganic sodium and potassium salts of iodates (IO3-) and iodides (I-); inorganic diatomic iodine (I2); and organic monatomic iodine (C-I).
Since diatomic gases such as nitrogen([N.sub.2]), oxygen([O.sub.2]), and hydrogen([H.sub.2]) are common in vacuum systems, it's necessary to realize that they will ionize into both monatomic and diatomic ions such as; [N.sub.2] [right arrow] [N.sub.2.sup.+] + [N.sup.+] where differing ionization efficiencies will occur due to the need to break the diatomic bond.
Acid cleaning, however, carries with it the inherent risk of glass damage when monatomic hydrogen atoms ([H.sup.0]), which are chargeless and very small, permeate the steel from the jacket side.
