Using the following equation how many grams of carbon dioxide do you get from 520 g of glucose: C6​H12​O6​+6O2​→H5​CO2​+6H2​O Your Answer: Question 2 (20 points) A student weighs 2.047 g of NaHCO3​. She then heats it in a test tube until the reaction is complete. How many grams Na2​CO3​ can be produced (in other words, what is the theoretical yield)? Don't write the unit, just the number with correct sig figs. (NaHCO3​=84.01 g/mol,Na2​CO3​=105.99 g/mol) 2NaHCO3​( s)→Na2​CO3​( s)+CO2​( g)+H2​O(g) Your Answer:
The mass of the Na2​CO3​ in the test tube after the reaction in Part A of the experiment is 0.7616 g. The theoretical yield is 0.9431 g. Find percent yield for this reaction. Write only the number, notithe % symbol. (NaHCO3​​=84.01 g/mol,Na2​CO3​=105.99 g/mol)2NaHCO3​( s)→Na2​CO3​( s)+CO2​( g)+H2​O(g)​ Your Answer: Answer
4.223 g of potassium bitartrate (KH5​C4​O6​( s)) are suspended in water and reacted with sodium carbonate (Na2​CO3​). How many grams of sodium carbonate are needed to react with this much potassium bitartrate? 2KH5​C4​O6​( s)+Na2​CO3​( s)+3H2​O(I)→CO2​( g)+2NaKH4​C4​O6​⋅4H2​O(s) Potassium bitartrate MM=188.18 g/mol, Rochelle salt MM=282.22 g/mol, Sodium carbonate MM=105.99 g/mol, Your Answer: Answer units
