You have to use systems of equations to solve the problem. Write down the systems you are using on paper and then use Matlab to solve the systems. Interprete your results from the Matlab computations again on your paper and give the final answers on the answer sheet. Balance the following chemical equation: _PbCrO4+ -- HCl + ----FESO4 → ----P6C12 + ----Cr2(SO4)3 + ----FeCl3 + ---H2O+ ----Fe2(SO4)3

2. In an ethanol production plant, a separator produces a 99% ethanol product from a feedstock stream containing 85% water and 15% ethanol at a rate of 450 Ib/min. The separator has two outlet streams: the ethanol product outlet stream (99% ethanol) and a residual water stream. 30% of the feedstock is bypassed and mixed with the residual water stream leaving the separator. If 60% of the ethanol entering the separator is recovered in the product stream, determine the composition of the residual water stream just after leaving the separator and the composition of the residual stream after mixing with the bypass stream.
