A 2.36-gram sample of NaHCO3 was completely decomposed in an experiment. 2NaHCO3 Na2CO3 + H2CO3
this experiment, carbon dioxide and water vapors combine to form H2CO3. After decomposition,
the Na2CO3 had a mass of 1.57
grams.
Determine the mass of the H2CO3 produced.
B. Calculate the percentage yield of H2CO3 for the reaction. Show your work or describe the
calculation process in detail.

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
