    The ones I've circled in red are all having different chemcal environments...these are 5 carbons The two in blue have the same env. as they are both next to the adjacent C atom in benzene next to the side chain so we will consider this 1 env. Same goes for both in green...they are BOTH next to...

    Because in the previous part u calculated no. of moles of NaOH. Now consider both the equations 2NaOH + SO2----> Na2SO3 +H2O NaOH + HCl ------> NaCl + H2O so u see that three moles of NaOH r required to react with one mole of SO2 and 1 of HCl. So to produce 1 mole of HCl and of SO2 the RCOOH...
