Extracted text: It is known that in a parallel reaction, product B (k= 0.8/hr) and product c (k=1.4/hr) are formed from reactant A with a 1st order reaction. Initial concentrations were measured as CAO=100mg/L, CBO=0, CCO=3 mg/L. Calculate the concentrations of the species in the medium 20 minutes after the start of the reaction.
