Enter the formula for each ionic compounds. express your answer as a chemical formula.<\/p>\n\n\n\n

Lead(II) chromate
Iron (III) fluoride
Iron(II) phosphate
Potassium hydroxide<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

Let’s break down the chemical formulas for each of these ionic compounds, keeping in mind the charges of the ions involved.<\/p>\n\n\n\n

1. Lead(II) Chromate:<\/strong><\/h3>\n\n\n\n
    \n
  • Formula:<\/strong> PbCrO\u2084<\/li>\n<\/ul>\n\n\n\n

    Explanation:<\/strong>
    Lead(II) chromate is made up of lead ions with a +2 charge and chromate ions with a -2 charge. Lead(II) is denoted as Pb\u00b2\u207a, and chromate is represented by CrO\u2084\u00b2\u207b. Since both the lead ion and chromate ion have equal and opposite charges, they combine in a 1:1 ratio to form PbCrO\u2084.<\/p>\n\n\n\n

    2. Iron (III) Fluoride:<\/strong><\/h3>\n\n\n\n
      \n
    • Formula:<\/strong> FeF\u2083<\/li>\n<\/ul>\n\n\n\n

      Explanation:<\/strong>
      Iron (III) fluoride is composed of iron(III) ions and fluoride ions. The iron(III) ion has a +3 charge (Fe\u00b3\u207a), and the fluoride ion has a -1 charge (F\u207b). To balance the charges, three fluoride ions are needed for every iron(III) ion. Therefore, the formula for iron (III) fluoride is FeF\u2083.<\/p>\n\n\n\n

      3. Iron (II) Phosphate:<\/strong><\/h3>\n\n\n\n
        \n
      • Formula:<\/strong> Fe\u2083(PO\u2084)\u2082<\/li>\n<\/ul>\n\n\n\n

        Explanation:<\/strong>
        Iron(II) phosphate consists of iron(II) ions and phosphate ions. The iron(II) ion has a +2 charge (Fe\u00b2\u207a), and the phosphate ion has a -3 charge (PO\u2084\u00b3\u207b). To balance the charges, three iron(II) ions are needed to combine with two phosphate ions, resulting in the formula Fe\u2083(PO\u2084)\u2082.<\/p>\n\n\n\n

        4. Potassium Hydroxide:<\/strong><\/h3>\n\n\n\n
          \n
        • Formula:<\/strong> KOH<\/li>\n<\/ul>\n\n\n\n

          Explanation:<\/strong>
          Potassium hydroxide is made up of potassium ions (K\u207a) and hydroxide ions (OH\u207b). The potassium ion has a +1 charge, and the hydroxide ion has a -1 charge. Since the charges of the two ions are equal in magnitude but opposite in sign, they combine in a 1:1 ratio to form the formula KOH.<\/p>\n\n\n\n

          Summary:<\/h3>\n\n\n\n
            \n
          • Lead(II) Chromate:<\/strong> PbCrO\u2084<\/li>\n\n\n\n
          • Iron(III) Fluoride:<\/strong> FeF\u2083<\/li>\n\n\n\n
          • Iron(II) Phosphate:<\/strong> Fe\u2083(PO\u2084)\u2082<\/li>\n\n\n\n
          • Potassium Hydroxide:<\/strong> KOH<\/li>\n<\/ul>\n\n\n\n

            Each formula is determined by balancing the positive and negative charges of the ions involved, ensuring that the compound is electrically neutral.<\/p>\n","protected":false},"excerpt":{"rendered":"
