Questions

A student determines the decоmpоsitiоn of NаHCO3 (sodium bicаrbonаte). A student placed the sample of NaHCO3 in a crucible and heated to determine the  moles of CO2 formed. The following data was recorded. The decomposition follows following reaction; 2NaHCO3 -----> Na2CO3 + H2O + CO2 What is the number of moles of bicarbonate heated?  What is the number of moles of CO2 formed? Mass of empty crucible       25.2550 g Mass of crucible  +  sample       26.5050 g Mass of sample (calculate)   ? Mass of crucible  + sample after heating 26.0050 g Mass of decomposition product  (calculate)   ? Mass of carbon dioxide lost (calculate)   ?
