Chile salt peter a source of NaNO_(3) also contains NaIO_(3) the NaIO_(3) is a source of I_(2) produced as shown in the following equation: Step I: IO_(3)^(ɵ)+3HSO_(3)^(ɵ)+3SO_(4)^(2-) Step II: 5I^(ɵ)+IO_(3)^(ɵ)+6H^(o+)to3I_(2)(s)+3H_(2)O One litre sample of chile salt peter solution containing 6.6 g NaIO_(3) is treated with NaHSO_(3) Now an additional amount of same solution is added to the reaction mixture to bring about the second titration. Calculate the weight of NaHSO_(3) requried in step I and what additional volume of chile salt peter mist be added in step II to bring out complete conversion of I^(ɵ) to I_(2) .

To get a closer finish in a 100 m race , the runners are given different starting positions depending upon how fast they can run . A starting position of +10 means that the runner starts 10 m in front of the start line and -5 means that the runner starts 5 m behind the start line . {:("Abbas",0,"Mike",-3,"Vicor",-20),("Peter",+10,"Tarush",+15,"Saher",+5):} How many metres are there between the starting positions of mike and peter ?
