(05.06 HC) When NaHCO3 completely decomposes, it can follow this balanced chemical equation: 2NaHCO3 → Na2CO3 + H2CO3 1) Determine the theoretical yields of each product using stoichiometry if the mass of the NaHCO3 sample is 3.80 grams. (Show work for both)
2) In an actual decomposition of NaHCO3, the mass of one of the products was measured to be 2.36 grams. Identify which product this could be and justify your reasoning.
3) Calculate the percent yield of the product identified in part 2. (Show your work)

Choose all that apply. when creating a graph, you should: determine the x- and y- variables label the scale on the x- and y- axes plot the data points draw a line of best fit to represent the data trend

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
