Give the balanced equation for the combustion of liquid hexane (C6H14) in the presence of oxygen gas<\/p>\n\n\n\n

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

The combustion of liquid hexane (C\u2086H\u2081\u2084) in the presence of oxygen (O\u2082) is a chemical reaction where hexane reacts with oxygen to produce carbon dioxide (CO\u2082) and water (H\u2082O). The balanced equation for this combustion 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

Explanation:<\/h3>\n\n\n\n
    \n
  1. Combustion reaction overview<\/strong>: Combustion is a reaction between a substance and oxygen, producing energy (usually in the form of heat and light). In the case of hexane, which is a hydrocarbon, the products of complete combustion are always carbon dioxide (CO\u2082) and water (H\u2082O).<\/li>\n\n\n\n
  2. Step-by-step balancing<\/strong>:\n
      \n
    • Carbon atoms<\/strong>: Hexane (C\u2086H\u2081\u2084) has 6 carbon atoms, so we need to produce 6 CO\u2082 molecules to balance the carbon atoms. This gives us: C6H14\u21926CO2C_6H_{14} \\rightarrow 6CO_2C6\u200bH14\u200b\u21926CO2\u200b<\/li>\n\n\n\n
    • Hydrogen atoms<\/strong>: Hexane has 14 hydrogen atoms. In water (H\u2082O), each molecule contains 2 hydrogen atoms, so to balance the hydrogen atoms, we need 7 H\u2082O molecules (since 7\u00d72=147 \\times 2 = 147\u00d72=14). C6H14\u21927H2OC_6H_{14} \\rightarrow 7H_2OC6\u200bH14\u200b\u21927H2\u200bO<\/li>\n\n\n\n
    • Oxygen atoms<\/strong>: Now, we count the oxygen atoms. On the product side, 6 CO\u2082 molecules contribute 12 oxygen atoms, and 7 H\u2082O molecules contribute 7 oxygen atoms, for a total of 19 oxygen atoms. Therefore, we need 19 O\u2082 molecules on the reactant side: O2\u219219OO_2 \\rightarrow 19OO2\u200b\u219219O<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • Final balanced equation<\/strong>: The coefficients now balance the number of atoms on both sides, resulting in the final balanced equation: 2C6H14+19O2\u219212CO2+14H2O2 C_6H_{14} + 19 O_2 \\rightarrow 12 CO_2 + 14 H_2O2C6\u200bH14\u200b+19O2\u200b\u219212CO2\u200b+14H2\u200bO<\/li>\n<\/ol>\n\n\n\n

      This equation shows that two molecules of hexane react with nineteen molecules of oxygen to produce twelve molecules of carbon dioxide and fourteen molecules of water. It follows the law of conservation of mass, meaning the number of atoms of each element is the same on both sides of the equation.<\/p>\n\n\n\n
