When NaHCO3 completely decomposes, it can follow this balanced chemical equation:2NaHCO3 → Na2CO3 + H2CO3Determine the theoretical yields of each product using stoichiometry if the mass of the NaHCO3 sample is 3.55 grams. (Show work for both)In an actual decomposition of NaHCO3, the mass of one of the products was measured to be 2.16 grams. Identify which product this could be and justify your reasoning.Calculate the percent yield of the product identified in part B. (Show your work)
