write complete balanced combustion reactions of hexane, cyclohexene, and toluene<\/p>\n\n\n\n

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

To write the balanced combustion reactions of hexane, cyclohexene, and toluene, we must first understand that combustion reactions involve a hydrocarbon (in this case, hexane, cyclohexene, and toluene) reacting with oxygen (O\u2082) to produce carbon dioxide (CO\u2082) and water (H\u2082O). The general form of a combustion reaction is:<\/p>\n\n\n\n

Hydrocarbon + Oxygen \u2192 Carbon Dioxide + Water<\/strong><\/p>\n\n\n\n

1. Combustion of Hexane (C\u2086H\u2081\u2084)<\/strong>:<\/h3>\n\n\n\n

The chemical formula for hexane is C\u2086H\u2081\u2084. The combustion reaction can be written as:<\/p>\n\n\n\n

C\u2086H\u2081\u2084 (l) + O\u2082 (g) \u2192 CO\u2082 (g) + H\u2082O (g)<\/strong><\/p>\n\n\n\n

Now, to balance the reaction:<\/p>\n\n\n\n

    \n
  • Carbon atoms: 6 in C\u2086H\u2081\u2084, so we need 6 CO\u2082 molecules.<\/li>\n\n\n\n
  • Hydrogen atoms: 14 in C\u2086H\u2081\u2084, so we need 7 H\u2082O molecules (since each water molecule contains 2 hydrogen atoms).<\/li>\n\n\n\n
  • Oxygen atoms: On the product side, we have 6 \u00d7 2 = 12 from CO\u2082 and 7 from H\u2082O, giving us 19 oxygen atoms. Therefore, we need 19\/2 molecules of O\u2082 to balance the equation.<\/li>\n<\/ul>\n\n\n\n

    The balanced reaction is:<\/p>\n\n\n\n

    2 C\u2086H\u2081\u2084 (l) + 19 O\u2082 (g) \u2192 12 CO\u2082 (g) + 14 H\u2082O (g)<\/strong><\/p>\n\n\n\n

    2. Combustion of Cyclohexene (C\u2086H\u2081\u2080)<\/strong>:<\/h3>\n\n\n\n

    Cyclohexene has the chemical formula C\u2086H\u2081\u2080. The combustion reaction can be written as:<\/p>\n\n\n\n

    C\u2086H\u2081\u2080 (l) + O\u2082 (g) \u2192 CO\u2082 (g) + H\u2082O (g)<\/strong><\/p>\n\n\n\n

    To balance:<\/p>\n\n\n\n

      \n
    • Carbon atoms: 6 in C\u2086H\u2081\u2080, so we need 6 CO\u2082 molecules.<\/li>\n\n\n\n
    • Hydrogen atoms: 10 in C\u2086H\u2081\u2080, so we need 5 H\u2082O molecules.<\/li>\n\n\n\n
    • Oxygen atoms: On the product side, we have 6 \u00d7 2 = 12 from CO\u2082 and 5 from H\u2082O, giving us 17 oxygen atoms. Therefore, we need 17\/2 molecules of O\u2082 to balance the equation.<\/li>\n<\/ul>\n\n\n\n

      The balanced reaction is:<\/p>\n\n\n\n

      2 C\u2086H\u2081\u2080 (l) + 17 O\u2082 (g) \u2192 12 CO\u2082 (g) + 10 H\u2082O (g)<\/strong><\/p>\n\n\n\n

      3. Combustion of Toluene (C\u2086H\u2086CH\u2083)<\/strong>:<\/h3>\n\n\n\n

      The chemical formula for toluene is C\u2086H\u2086CH\u2083. The combustion reaction is:<\/p>\n\n\n\n

      C\u2086H\u2086CH\u2083 (l) + O\u2082 (g) \u2192 CO\u2082 (g) + H\u2082O (g)<\/strong><\/p>\n\n\n\n

      To balance:<\/p>\n\n\n\n

        \n
      • Carbon atoms: 7 in C\u2086H\u2086CH\u2083, so we need 7 CO\u2082 molecules.<\/li>\n\n\n\n
      • Hydrogen atoms: 8 in C\u2086H\u2086CH\u2083, so we need 4 H\u2082O molecules.<\/li>\n\n\n\n
      • Oxygen atoms: On the product side, we have 7 \u00d7 2 = 14 from CO\u2082 and 4 from H\u2082O, giving us 18 oxygen atoms. Therefore, we need 18\/2 molecules of O\u2082 to balance the equation.<\/li>\n<\/ul>\n\n\n\n

        The balanced reaction is:<\/p>\n\n\n\n

        2 C\u2086H\u2086CH\u2083 (l) + 18 O\u2082 (g) \u2192 14 CO\u2082 (g) + 16 H\u2082O (g)<\/strong><\/p>\n\n\n\n

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

        Combustion reactions are exothermic, meaning they release energy, and they follow a set stoichiometric pattern to ensure that the number of atoms of each element is conserved. For these reactions, balancing involves ensuring that:<\/p>\n\n\n\n

          \n
        1. The carbon atoms in the hydrocarbon are accounted for in CO\u2082.<\/li>\n\n\n\n
        2. The hydrogen atoms are accounted for in H\u2082O.<\/li>\n\n\n\n
        3. The oxygen atoms on the reactant side match the number of oxygen atoms required to form CO\u2082 and H\u2082O on the product side.<\/li>\n<\/ol>\n\n\n\n

          This balancing process is essential for achieving a correct and consistent representation of the chemical reaction and ensuring the conservation of mass.<\/p>\n\n\n\n
