H2O2

H_2O_2 is reduced rapidly by Sn^(2+). H_2O_2 is decomposed slowly at room temperature to yeild O_2 and H_2O_2 . 136g of 10% by mass of H_2O_2 in water is treated with 100mL of 3M Sn^(2+) and then a mixture is allowed to stand until no further reaction occurs. The reactions involved are: 2H^(o+)+H_(2)O_(2)+Sn^(2+)toSn^(4+)+2H_(2) 2H_(2)O_(2)to2H_(2)O+O_(2) The equivalent of H_2O_2 reacted with Sn^(2+) is

H_2O_2 is a

For H_2O_2 -

The reaction 2H_2O_2 to 2H_2O + O_2 is a

In the following reaction 2H_2O_2 to 2H_2O + O_2 rate of formation of O_2 is 36g "min"^(-1) What is rate of disappearance of H_2O_2 ?

In which of the following reactions H_2O_2 acts as a reducing agent ? (i) H_2O_2+2H^(+)+2e^(-)to 2H_2O (ii) H_2O_2-2e^(-) to O_2+2H^(+) (iii) H_2O_2+2e^(-) to 2OH^(-) (iv) H_2O_2+2OH^(-)-2e^(-) to O_2+2H_2O

In reaction of H_2O_2 and alkaline K_3[Fe(CN)_6], H_2O_2 acts as
