Dyneema Â® SK60 is the only super-fiber with a density below 1.0 (the fiber can float on water). The specific gravity of Dyneema Â® SK60 is 0.97, which is the lowest value among super fibers and is lighter than water.
Benzalkonium chloride is a quaternary ammonium compound and is used as a preservative in many ophthalmic solutions. Typically in dilutions of 0.01% or less.lkyl triethanol ammonium chloride, benzethonium chloride, CETRIMIDE (cetyltrimethylammonium bromide), DYMED and POLYQUAD are also examples of quaternary ammonium compounds that are used in ophthalmic preparations.
SrO, LiI, NH3, ICl, NH4Cl, SO2 Alright, I know that molecular compounds contain only nonmetals and ionic compounds generally contain both metals and nonmetals... also, ammonium compounds (those containing the NH4 cation) are examples of ionic compounds made up solely of nonmetals. I'm just not sure about... show more SrO, LiI, NH3, ICl, NH4Cl, SO2 Alright, I know that molecular compounds contain only nonmetals and ionic compounds generally contain both metals and nonmetals... also, ammonium compounds (those containing the NH4 cation) are examples of ionic compounds made up solely of nonmetals.
