Formic acid - WikiMili, The Best Wikipedia Reader
Formic acid in 85% concentration is flammable, and diluted formic acid is on the U.S. Food and Drug Administration list of food additives.  The principal danger from formic acid is from skin or eye contact with the concentrated liquid or vapors. The U.S. OSHA Permissible Exposure Level of formic acid vapor in the work environment is 5 parts per million parts of air ().
Argon - Blogger
Argon is a chemical element with syol Ar and atomic nuer 18. It is in group 18 of the periodic table and is a noble gas.  Argon is the third-most abundant gas in the Earth''s atmosphere, at 0.934% (9340 ppmv). It is more than twice as abundant as water

IRC +10216 as a spectroscopic laboratory: improved …
Disilicon carbide has a C 2v symmetry and a 1 A 1 electronic ground state with a modest permanent dipole moment of ~ 1D along the b axis (McCarthy et al. 2015). Because the two equivalent off-axis silicon atoms are bosons, only half of the rotational levels exist (those with K a + K c even).

Another advantage of X-Fab is that its manufacturing line uses 6-inch-wide (15-centimeter) silicon carbide wafers instead of the 4-inch (10-cm) wafers used by other manufacturers.
Angewandte Chemie: Early View - Wiley Online Library
Titanium carbide nanoparticle alysts were obtained in the gas phase and chiral SWNTs with fourfold symmetry were grown thermodynamically from the (2 0 0) plane of titanium carbide. The sample contained an abundance of (16,8) tubes with about a 74 % content.

Potassium chloride — Wikipedia Republished // WIKI 2
Potassium chloride (KCl) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water and its solutions have a salt-like taste. KCl is used as a fertilizer, in medicine, in …
Cyanamide/Cyanamide - /
Cyanamide is produced by hydrolysis of calcium cyanamide, which in turn is prepared from calcium carbide via the Frank-Caro process. CaCN 2 + H 2 O + CO 2 → CaCO 3 + H 2 NCN The conversion is conducted on slurries. Consequently, most commercial
Chemical formula — Wikipedia Republished // WIKI 2
Chemical formula. Quite the same Wikipedia. Just better. The connectivity of a molecule often has a strong influence on its physical and chemical properties and behavior. Two molecules composed of the same nuers of the same types of atoms (i.e. a pair of isomers) might have completely different chemical and/or physical properties if the atoms are connected differently or in different positions.
