During a laboratory experiment, a 2.36-gram sample of NaHCO3 was thermally decomposed. In this experiment, carbon dioxide and water vapors escape and are combined to form carbonic acid. After decomposition, the sample weighed 1.57 grams. Calculate the percentage yield of carbonic acid for the reaction. Describe the calculation process in detail. NaHCO3 → Na2CO3 + H2CO3
