3
The source of calcium carbonate is limestone that contains 91% CaCO3 and 9% solid inerts. Meanwhile, the carbon source is coal that
contains 60% C and 7% ash, the remainder being volatile matter. 4,800 kg limestone and 5,850 kg coal are fed to the reactor, which
produces a gaseous and a solid product. Some of the carbon become CO2 and CO, and all the volatile matter are gasified and join the
gaseous product. All solid components join the solid product leaving the reactor. The first reaction is 95% complete and the second 90%.
Determine the amount of the solid product and the percent purity of CaC2 in it using molecular balances.
