3.40. After 20 minutes of heating, the mass of CaCO3 decreased from 15 g to 11.5 g. Calculate the yield of the decomposition. Further calculate the mass of pure CaO and the mass fraction of CaCO3 in a final mixture. M(CaCO3) = 99.95 g/mol, M(CaO) = 55.96 g/mol, M(CO2) = 43.99 g/mol. CaCO3 + CaO + CO2 BU
