Why are many ionic compounds not soluble in water? A. They are non-polar and do not mix well with H2O B. They have metals that are much denser than water C. They have high charge density which makes stronger ionic bonds that water can’t break D. They have weak ionic bonds that cause them to precipitate E. The higher pressure of water causes solids to precipitate

Our present world could not exist without hydrocarbons. Nearly everything we touch today is either comprised of or coated with hydrocarbon products. In the practice of clinical toxicology, initial efforts usually entail precisely determining the specific xenobiotics that might be involved in a specific exposure, followed by defining the type and extent of the exposure. In this regard, hydrocarbon exposures are always clinically challenging. Despite significant chemical diversity, most classification schemes group hydrocarbons by specific uses or applications, rather than...
