Oxide

Oxide - Nonmetal oxides: All nonmetals form covalent oxides with oxygen, which react with water to form acids or with bases to form salts. Most nonmetal oxides are acidic and form oxyacids, which in turn yield hydronium ions (H3O+) in aqueous solution. There are two general statements that describe the behaviour of acidic oxides. First, oxides such as sulfur trioxide (SO3) and dinitrogen
