Propanoic acid reacts with calcium carbonate, producing calcium propanoate, carbon dioxide and water. What equation represents this reaction?
- A$2\text{C}_2\text{H}_5\text{COOH} + \text{CaCO}_3 \rightarrow 2\text{C}_2\text{H}_5\text{COOCa} + \text{CO}_2 + \text{H}_2\text{O}$
- B$2\text{C}_2\text{H}_5\text{COOH} + \text{CaCO}_3 \rightarrow (\text{C}_2\text{H}_5\text{COO})_2\text{Ca} + \text{CO}_2 + \text{H}_2\text{O}$
- C$2\text{C}_3\text{H}_7\text{COOH} + \text{CaCO}_3 \rightarrow 2\text{C}_3\text{H}_7\text{COOCa} + \text{CO}_2 + \text{H}_2\text{O}$
- D$2\text{C}_3\text{H}_7\text{COOH} + \text{CaCO}_3 \rightarrow (\text{C}_3\text{H}_7\text{COO})_2\text{Ca} + \text{CO}_2 + \text{H}_2\text{O}$
