A student mixes vinegar and baking soda, observing vigorous bubbling and a temperature drop. Which equation best represents this reaction?

• A. CH₃COOH(aq) + NaOH(s) → CO₂(g) + H₂O(l) + NaCH₃COO(aq)
• B. CH₃COOH(aq) + Na₂CO₃(s) → CO₂(g) + H₂O(l) + NaCH₃COO(aq)
• C. CH₃COOH(aq) + NaHCO₃(s) → CO₂(g) + H₂O(l) + NaCH₃COO(aq)
• D. CH₃COOH(aq) + NaCl(s) → CO₂(g) + H₂O(l) + NaCH₃COO(aq)

Answer: (C)
