Write the chemical formula of these coordination compounds. formula name dicarbonyldichloromanganese(IV) bromide tetraamminedibromoplatinum(IV) bromide potassium aquapentachlorocobaltate(III)<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Here are the chemical formulas for the coordination compounds you mentioned:<\/p>\n\n\n\n

    \n
  1. Dicarbonyldichloromanganese(IV) bromide<\/strong>
    The name indicates that there are two carbonyl groups (CO), two chlorine (Cl) atoms, and one manganese ion in the +4 oxidation state (Mn4+), along with a bromide ion (Br\u2212).
    The formula would be:
    Mn(CO)2Cl2Br<\/strong>Explanation<\/strong>:\n
      \n
    • The “dicarbonyl” part refers to two carbon monoxide (CO) ligands attached to the central metal, manganese.<\/li>\n\n\n\n
    • “Dichloro” indicates two chloride ions (Cl\u2212) bound to the metal.<\/li>\n\n\n\n
    • The “bromide” ion is also a ligand and is present as Br\u2212.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Tetraamminedibromoplatinum(IV) bromide<\/strong>
      This compound consists of a platinum ion (Pt4+) coordinated with four ammonia molecules (NH3), two bromine ions (Br\u2212) attached to the platinum, and an additional bromide ion as a counterion.
      The formula is:
      [Pt(NH3)4Br2]Br<\/strong>Explanation<\/strong>:\n
        \n
      • “Tetraamine” indicates four ammonia molecules as ligands.<\/li>\n\n\n\n
      • “Dibromo” specifies two bromine ions as ligands attached to platinum.<\/li>\n\n\n\n
      • Platinum is in the +4 oxidation state, as indicated by the “(IV)” in the name.<\/li>\n\n\n\n
      • The second bromide ion (Br\u2212) is the counterion balancing the charge of the complex.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Potassium aquapentachlorocobaltate(III)<\/strong>
        This compound consists of a cobalt ion (Co3+) in the +3 oxidation state, coordinated with five chloride ions (Cl\u2212) and one water molecule (H2O), with potassium (K+) acting as a counterion.
        The formula would be:
        K[CoCl5(H2O)]<\/strong>Explanation<\/strong>:\n
          \n
        • “Aquapenta” means one water molecule (H2O) is coordinated with the cobalt ion.<\/li>\n\n\n\n
        • “Chlorocobaltate” indicates five chloride ions (Cl\u2212) bound to the cobalt ion.<\/li>\n\n\n\n
        • The cobalt ion is in the +3 oxidation state (Co3+), as denoted by “(III)”.<\/li>\n\n\n\n
        • Potassium (K+) is the counterion that balances the overall charge of the complex.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

          In summary, the chemical formulas are:<\/p>\n\n\n\n

            \n
          1. Mn(CO)2Cl2Br<\/strong><\/li>\n\n\n\n
          2. [Pt(NH3)4Br2]Br<\/strong><\/li>\n\n\n\n
          3. K[CoCl5(H2O)]<\/strong><\/li>\n<\/ol>\n\n\n\n
