From the attachment: the recorded data Before CuO + porcelain boat = 62.869g CaCl2 + U tube = 80.483g After: Porcelain boat + contents = 54.869g CaCl2 + U tube = 89.483g. Why was the CaCl2 tube between the generator and the tube containing the porcelain boat? a) to absorb evaporated HCl b) to absorb evaporated H2O c) to slow down the gases released d) to absorb the evaporated Zn particles e) to remove the initial air that passes through the tube which one is the answer? Our teacher doesn't do much lab work with us so please help. thanks.
