P2. lodine is commercially obtained by the reaction of seaweed with MnO_(2) and H_(2)SO_(4). 2NaI+MnO_(2)+2H_(2)SO_(4)rarrNa_(2)SO_(4)+MnSO_(4)+2H_(2)O+I_(2) 20% more H_(2)SO_(4) is fed to the reactor. The mixture leaving the reactor is sent to a separator to obtain a product containing 54%I_(2) and 46%H_(2)O by mass. The waste stream taken from the separator contains H_(2)O,MnSO_(4),Na_(2)SO_(4) and inert substances. The unreacted Nal and H_(2)SO_(4) are taken from the separator and fed back to the reactor. Considering that the seaweed contains 5%Nal,30%H_(2)O and 65% inert substances by mass and the reaction occurs at a single pass conversion of 80%. a) The amount of kgl_(2) obtained from 1 ton of seaweed, b) The amount and mass composition of the waste st Use matlabe
