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

The correct formula for calcium acetate is d) Ca(C2H3O2)2<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n
    \n
  1. Calcium Ion (Ca\u00b2\u207a):<\/strong>
    Calcium is a metal in group 2 of the periodic table, meaning it forms ions with a +2 charge. This is because it loses two electrons to achieve a stable electron configuration.<\/li>\n\n\n\n
  2. Acetate Ion (C\u2082H\u2083O\u2082\u207b):<\/strong>
    The acetate ion is a polyatomic ion with the formula C\u2082H\u2083O\u2082\u207b (sometimes written as CH\u2083COO\u207b), which has a -1 charge. Acetate comes from acetic acid (CH\u2083COOH) and carries a negative charge after losing a proton (H\u207a).<\/li>\n\n\n\n
  3. Balancing Charges:<\/strong>
    In order to form a neutral ionic compound, the total positive charge must balance the total negative charge. Since the calcium ion has a +2 charge (Ca\u00b2\u207a) and the acetate ion has a -1 charge (C\u2082H\u2083O\u2082\u207b), you need two acetate ions to balance one calcium ion.<\/li>\n<\/ol>\n\n\n\n
      \n
    • Calcium ion: Ca\u00b2\u207a (charge = +2)<\/li>\n\n\n\n
    • Acetate ion: C\u2082H\u2083O\u2082\u207b (charge = -1) To balance the charges:
      [
      \\text{1 calcium ion (Ca\u00b2\u207a)} \\text{ requires 2 acetate ions (C\u2082H\u2083O\u2082\u207b) to balance the charges, resulting in a neutral compound.}
      ]<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Formula:<\/strong>
        The formula for calcium acetate is therefore Ca(C\u2082H\u2083O\u2082)\u2082. The parentheses around C\u2082H\u2083O\u2082 indicate that two acetate ions are present, as required to balance the +2 charge of the calcium ion. Without the parentheses, it would incorrectly imply just one acetate ion.<\/li>\n<\/ol>\n\n\n\n

        In summary, the correct formula is Ca(C\u2082H\u2083O\u2082)\u2082<\/strong>, which ensures charge neutrality between the calcium and acetate ions.<\/p>\n","protected":false},"excerpt":{"rendered":"
