As a molecular these two ions combine together under electrostatic attraction (opposite charges - like N & S poles of magnets). Data Table 6. magnesium chloride. Carbon subsulfide is an inorganic chemical compound with the formula C 3 S 2. List ionic or Molecular bond. Terms in this set (168) NaCl. MgCl2. Remember to first determine whether the compound is ionic or molecular! Sr3P2. potassium oxide. However, the lead in is oxidation state two (Pb2+) and the carbonate anion is CO32-. This deep red liquid is immiscible with water but soluble in organic solvents. aluminum sulfide. Chromium is a transition metal cation and CO${_3}$ is an anion with a charge of 2-, as said in my chemistry textbook. Hardness. Cs
