Hydrogen and oxygen combine to from `H_(2) O_(2) ` and `H_(2)O` containing `5.93%` and `11.2%` hydrogen respectively . The data illustrates :

Compare the structures of H_2O and H_2O_2 .

19 gm of ice is converted into water at 0^(@)C and 1 atm. The entropies of H_(2)O(s) and H_(2)O(l) are 38.2 and 60 J//"mol " K respectively. The enthalpy change for this conversion is :

The structure of H_2O_2 is

An organic substance containing carbon, hydrogen and oxygen gave following percentages, C= 40.68%, H_(2) = 5.085% and O_(2) = 54.22%. The vapour density of the compound is 59. Calculate the molecular formula of the compound.

The strength of H_(2)O_(2) is expressed in several ways like molarity, normality,% (w/V), volume strength, etc. The strength of "10 V" means 1 volume of H_(2)O_(2) on decomposition gives 10 volumes of oxygen at 1 atm and 273 K or 1 litre of H_(2)O_(2) gives 10 litre of O_(2) at 1 atm and 273 K The decomposition of H_(2)O_(2) is shown as under : H_(2)O_(2)(aq) to H_(2)O(l)+(1)/(2)O_(2)(g) H_(2)O_(2) can acts as oxidising as well as reducing agent. What is the percentage strength (%w/V) of "11.2 V" H_(2)O_(2)

The strength of H_(2)O_(2) is expressed in several ways like molarity, normality,% (w/V), volume strength, etc. The strength of "10 V" means 1 volume of H_(2)O_(2) on decomposition gives 10 volumes of oxygen at 1 atm and 273 K or 1 litre of H_(2)O_(2) gives 10 litre of O_(2) at 1 atm and 273 K The decomposition of H_(2)O_(2) is shown as under : H_(2)O_(2)(aq) to H_(2)O(l)+(1)/(2)O_(2)(g) H_(2)O_(2) can acts as oxidising as well as reducing agent. As oxidizing agent H_(2)O_(2) is converted into H_(2)O and as reducing agent H_(2)O_(2) is converted into O_(2) . For both cases its n-factor is 2. :. "Normality " "of" H_(2)O_(2) " solution " =2xx " molarity of" H_(2)O_(2) solution What is the molarity of "11.2 V" H_(2)O_(2) ?

Name the type of reactions.By passing elecrtic current through water, H_2 and O_2 are obtained as 2H_2O overset(El ectric current)rarr 2H_2 +O_2 But H_2 and O_2 can also be combined to form water 2H_2 + O_2 rarr 2H_2O
