[CdI4]2-. [HgI4]2-. [PbI4]2-.PbI does not exist. There are, however PbI2 and PbI4. Neither are good electrolytes. Lead (II) iodide, which has PbI2 as its chemical formula, exists only this way and not in the form PbI4 as someone might guess. Asked By Wiki User. What is the compound name for N2Br5?Within the Chemical Engineering Journal, the Environmental Chemical Engineering section presents papers dealing with emerging topics in environmental chemical and process engineering, including pollution control, separation processes, advanced oxidation processes, adsorption of contaminants...The four heme groups in a hemoglobin molecule are represented as disks. Each heme group contains one Fe2+ ion and one porphyrin ring. 1. Cations are always named before anions, with a space between their names. 2. In naming the coordination sphere, ligands are named in alphabetical order.
