One of the methods of preparation of per disulphuric acid, H_(2)S_(2)O_(8) , involve electrolytic oxidation of H_(2)SO_(4) at anode (2H_(2)SO_(4)toH_(2)S_(2)O_(8)+2H^(+)+2e^(-)) with oxygen ad hydrogen as by-products in such an electrolysis, 9.722 L of H_(2) and 2.35L of O_(2) were generated at STP. What is the weighht of H_(2)S_(2)O_(8) formed?

The integral enthalpy of solution in kJ of one mole of H_(2)SO_(4) dissolved in n mole of water is given by : DeltaH_(s)=(75.6xxn)/(n+1.8) Calculate DeltaH for the following processes : (a) 1 mole of H_(2)SO_(4) dissolved in 2 mole of H_(2)O . (b) 1 mole of H_(2)SO_(4) dissolved in 7 mole of H_(2)O . (c ) 1 mole of H_(2)SO_(4) dissolved in 5 mole of H_(2)O . (d) solution (a) dissolved in 5 mole of H_(2)O . (e) 1 mole of H_(2)SO_(4) dissolved in excess of H_(2)O .

During the electrolysis of conc H_(2)SO_(4) , it was found that H_(2)S_(2)O_(8) and O_(2) liberated in a molar ratio of 3:1 . How many moles of H_(2) were found of moles of H_(2)S_(2)O_(8) ? ( Express your answer as :3xx mol e s of H_(2), integer answer is between 0 and 5 0

Number of moles of O_(2) formed by 136g of H_(2)O_(2) , on complete decomposition will be:

0.2 mole sample of hydrocarbon C_(x)H_(y) yields after complete combustion with excess O_(2) gas, 0.8 mole of CO_(2) 1.1 mole of H_(2)O . Hence hydrocarbon is

H_(2)underline(S)O_(5)+H_(2)O to H_(2)SO_(4)+H_(2)O_(2)
