cons 4811445585 Tuesday Ques 1 Balance the following equations in basie medium by any method Coxidation no. method or son electron method) a)N2H4+ClO3->NO+Cl-​

Answer 1

Answer:

●OXIDATION REACTION :-

N2H4 ----> NO

[1st step]

● First balance the nitrogens :-

N2H4 ---> 2N0

___________

[2nd step]

●Next balance balance the oxygens by adding water :-

N2H4 + 2H2O -----> 2NO

___________

[3rd step]

●balance the hydrogens by adding H+

N2H4 + 2H2O ----> 2NO + 8H+

___________

[4th step]

●Finally balance the charge by adding electrons :-

N2H4 + 2H2O ---> 2NO + 8H+ 8e-

________________________________

NOW

●REDUCTION REACTION :-

[1st step]

ClO3(-) ----> Cl(-)

_____________

[2nd step]

ClO3(-) ----> Cl(-) + 3H2O

_____________

[3rd step]

ClO3(-) + 6H+ -----> Cl(-) + 3H2O

_____________

[4th step]

ClO3(-) + 6H+ + 6e(-) ----> Cl(-) + 3H2O

___________________________________-

●Finally we are combined the two reaction ,

we get.. but we need to have the no. of electron to be equal in both half reaction , so we multiply oxidizing reaction by 3 and reduction reaction by 4

after that,

●Combined and canceling out the common product we get final balanced reaction

◢FINAL REACTION :-

3N2H4 + 4ClO3(-) ----> 6NO + 4Cl(-) + 6H2O
