Part A Copper(II) chlorate. Express your answer as a chemical formula: Cu(ClO3)2<\/p>\n\n\n\n

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

Correct Answer: CuClO\u2083<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

The chemical formula for an ionic compound is determined by balancing the charges of its constituent ions to create a neutral compound. The name “copper(I) chlorate,” as shown in the image, provides all the necessary information to derive this formula.<\/p>\n\n\n\n

    \n
  1. Identify the Cation (Positive Ion):<\/strong>\u00a0The first part of the name, “copper(I),” identifies the cation.\n
      \n
    • “Copper”<\/strong>\u00a0is the element with the chemical symbol\u00a0Cu<\/strong>.<\/li>\n\n\n\n
    • The Roman numeral\u00a0(I)<\/strong>\u00a0indicates the charge of the copper ion. In this case, it signifies a +1 charge. Therefore, the cation is the copper(I) ion, written as\u00a0Cu\u207a<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Identify the Anion (Negative Ion):<\/strong>\u00a0The second part of the name, “chlorate,” identifies the anion.\n
        \n
      • Chlorate is a polyatomic ion, meaning it is a group of covalently bonded atoms that carries an overall charge.<\/li>\n\n\n\n
      • The chemical formula for the chlorate ion is\u00a0ClO\u2083<\/strong>, and it has a charge of\u00a0-1<\/strong>. Therefore, the anion is\u00a0ClO\u2083\u207b<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Balance the Charges:<\/strong>\u00a0The goal is to combine the cation (Cu\u207a) and the anion (ClO\u2083\u207b) in a ratio that results in a net charge of zero.\n
          \n
        • The charge of one copper(I) ion is +1.<\/li>\n\n\n\n
        • The charge of one chlorate ion is -1.<\/li>\n\n\n\n
        • A one-to-one ratio of these ions will balance the charges perfectly: (+1) + (-1) = 0.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • Write the Chemical Formula:<\/strong>\u00a0To write the final formula, you combine the symbols for the cation and anion. The cation is written first, followed by the anion. Since only one of each ion is needed, no subscripts are required.<\/li>\n<\/ol>\n\n\n\n

          Therefore, the correct chemical formula for copper(I) chlorate is CuClO\u2083<\/strong>.<\/p>\n\n\n\n

          Note: This is different from copper(II) chlorate, which contains the copper(II) ion (Cu\u00b2\u207a). To balance the +2 charge of Cu\u00b2\u207a, two chlorate ions (ClO\u2083\u207b) would be needed, resulting in the formula Cu(ClO\u2083)\u2082.<\/em><\/p>\n\n\n\n
