Question 10
(05.06 HC)
A 3.81-gram sample of NaHCO3 was completely decomposed in an experiment.
2NaHCO3-Na₂CO3 + H₂CO3
In this experiment, carbon dioxide and water vapors combine to form H₂CO3. After decomposition, the Na₂CO3 had
a mass of 2.86 grams.
1. Determine the mass of the H₂CO3 produced.
2. Calculate the percentage yield of H₂CO3 for the reaction. Show your work or describe the calculation
