A 2.36-gram sample of NaHCO, was completely decomposed in an experiment. 2NaHCO3-Na2CO, + H2CO3
In this experiment carbon dioxide and water vapors combine to form H2CO3. After decomposition the Na2C0s had a mass of 1.57 grams.
A. Determine the mass of the H2CO, produced
B. Calculate the percentage yield of H. CO, for the reaction. Show your work or describe the calculation process in detail.
