Contracts against the public policy of the law, are equally void as if they were in violation of a public statute; a contract not to marry any one, is therefore illegal and void. See Void. 5.
Phosphorus is a fascinating element that occurs in at least three very different forms. If left exposed to the air, it catches fire on its own. It also glows in the dark. Today, its most important use is in the manufacture of phosphoric acid (H 3 PO 4 ).
Phosphorus is used almost entirely in the form of compounds, usually in the oxidation states of +3, +5, and â3. Unlike nitrogen and various other members of the family, phosphorus tends to exhibit a preference for the +5 state. Of considerable economic significance is phosphine, or hydrogen phosphide, PH3.
