The balanced equation for the combustion of butane is: 2C4\u200bH10\u200b+13O2\u200b 8CO2\u200b+10H2\u200bO<\/p>\n\n\n\n

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

The balanced chemical equation for the combustion of butane (( C_4H_{10} )) is:<\/p>\n\n\n\n

[
2C_4H_{10} + 13O_2 \\rightarrow 8CO_2 + 10H_2O
]<\/p>\n\n\n\n

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

Combustion is a chemical reaction in which a substance reacts with oxygen, releasing energy in the form of heat and light. Butane (( C_4H_{10} )), a hydrocarbon, undergoes complete combustion in the presence of excess oxygen (( O_2 )), producing carbon dioxide (( CO_2 )) and water (( H_2O )).<\/p>\n\n\n\n

Step-by-Step Balancing:<\/strong><\/h4>\n\n\n\n
    \n
  1. Carbon Atoms:<\/strong> Butane has 4 carbon atoms per molecule. Since 2 molecules of butane are involved, we need ( 2 \\times 4 = 8 ) carbon atoms in the products. This means 8 molecules of ( CO_2 ) are needed.<\/li>\n\n\n\n
  2. Hydrogen Atoms:<\/strong> Each butane molecule has 10 hydrogen atoms. Since we have 2 molecules, there are ( 2 \\times 10 = 20 ) hydrogen atoms. To balance this, we need 10 molecules of ( H_2O ) (since each water molecule contains 2 hydrogen atoms).<\/li>\n\n\n\n
  3. Oxygen Atoms:<\/strong> On the right side, there are ( 8 \\times 2 = 16 ) oxygen atoms from ( CO_2 ) and ( 10 \\times 1 = 10 ) oxygen atoms from ( H_2O ), totaling 26 oxygen atoms<\/strong>. To balance this, we need 13 molecules of ( O_2 ) (since each molecule contains 2 oxygen atoms, giving ( 13 \\times 2 = 26 ) oxygen atoms).<\/li>\n<\/ol>\n\n\n\n

    Thus, the equation is balanced:
    ( 2C_4H_{10} + 13O_2 \\rightarrow 8CO_2 + 10H_2O )<\/strong><\/p>\n\n\n\n

    Importance:<\/h3>\n\n\n\n
      \n
    • Complete combustion<\/strong> ensures maximum energy output and minimal pollution.<\/li>\n\n\n\n
    • Incomplete combustion<\/strong> occurs with limited oxygen, producing carbon monoxide (( CO )), a toxic gas.<\/li>\n\n\n\n
    • This reaction is commonly used in lighters, stoves, and gas heaters.<\/li>\n<\/ul>\n\n\n\n
