In some types of alcohol digéstion, alcohol \( \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH} \) is broken down int vinegar, \( \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2} \) and water. Which of the following describes this reaction? Choose 1 answer: (A) \( 2 \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+\mathrm{O}_{2} \rightarrow 2 \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2}+\mathrm{H}_{2} \mathrm{O} \) (B) \( 2 \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+2 \mathrm{O}_{2} \rightarrow \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2}+\mathrm{H}_{2} \mathrm{O} \) (C) \( 2 \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+2 \mathrm{O}_{2} \rightarrow \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2}+3 \mathrm{H}_{2} \mathrm{O} \) (D) \( \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+\mathrm{O}_{2} \rightarrow \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2}+\mathrm{H}_{2} \mathrm{O} \)

Answer

The correct reaction is: \( \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH} + \mathrm{O}_{2} \rightarrow \mathrm{HC}_{2} \mathrm{H}_{3} \mathrm{O}_{2} + \mathrm{H}_{2} \mathrm{O} \) Choice D.

Solution

To determine which reaction is correct, we must ensure that the equation is balanced (the number of each type of atom must be the same on both sides of the arrow). The reaction is: Ethanol (C₂H₅OH) + O₂ → Acetic acid (HC₂H₃O₂) + H₂O Let’s check option (D):   C₂H₅OH + O₂ → HC₂H₃O₂ + H₂O Step 1. Write formulas:   Ethanol: C₂H₅OH can be rewritten as C₂H₆O   Acetic acid: HC₂H₃O₂ can be rewritten as C₂H₄O₂   Water: H₂O Step 2. Count atoms on each side. Left Side:   Carbon (C): 2 (from C₂H₆O)   Hydrogen (H): 6 (from C₂H₆O)   Oxygen (O): 1 (from C₂H₆O) + 2 (from O₂) = 3 Right Side:   Carbon (C): 2 (from C₂H₄O₂)   Hydrogen (H): 4 (from C₂H₄O₂) + 2 (from H₂O) = 6   Oxygen (O): 2 (from C₂H₄O₂) + 1 (from H₂O) = 3 Both sides have:   C: 2  H: 6  O: 3 Since the equation is balanced, option (D) is the correct description of the reaction. Answer: (D)

Extra Insights

Did you know that the process of turning alcohol into vinegar is called fermentation? This fascinating transformation is often utilized in the culinary world, where vinegar is a fundamental ingredient in dressings, marinades, and pickling solutions. The fermentation process typically involves yeast and certain types of bacteria that convert the ethanol into acetic acid, giving vinegar its tangy flavor and various uses in cooking! When it comes to solving chemical equations, one common mistake is not balancing the equation properly. It's important to ensure that the number of atoms for each element is the same on both sides of the equation. For example, when dealing with reactions, double-check coefficients and make sure you've accounted for all products and reactants correctly. This practice not only avoids confusion but also ensures your understanding of the stoichiometry involved in chemical reactions!
