Sodium hydrogen carbonate (baking soda) decomposes upon heating to form carbon dioxide gas, water, and sodium carbonate. A crucible is a ceramic container that can be used for decomposition reactions since it can withstand high temperatures. To study the decomposition of sodium hydrogen carbonate, you would place a measured amount of sodium hydrogen carbonate in a crucible, heat over a bunsen burner for several minutes, and then mass the cooled product. The following data was collected during this reaction:
Item
Mass (g)
Mass of Crucible
19.85
Crucible + NaHCO3
24.04
Crucible + Na2CO3
22.20
Mass of Na2CO3
?
A) Write the complete balanced equation (same rules as question 1)
--> + +
B) Calculate the mass of NaHCO3 used in the experiment: g
C) What is the Theoretical Yield of sodium carbonate (in grams)? g
D) Calculate the actual mass of the sodium carbonate? g
E) Calculate the % yield of the reaction. %
