What is oxidized and what is reduced in this reaction?

N2H4(l) + 2H2O2(l) → N2(g) + 4H2O(g)

N is reduced and H is oxidized.

N is reduced and O is oxidized.

N is oxidized and O is reduced.

N is oxidized and H is reduced.

Respuesta :

the answer is C
N is oxidized and O is reduced

Answer: N is oxidized and O is reduced.

Explanation:

[tex]N_2H_4(l)+2H_2O_2(l)\rightarrow N_2(g)+4H_2O(g)[/tex]

Oxidation: Removal of hydrogen or addition of oxygen is termed as oxidation.

Reduction: Removal of  oxygen or addition of hydrogen is termed as reduction.

In a given reaction,

  • Removal of hydrogen from [tex]N_2H_4[/tex] gives [tex]N_2[/tex] gas which means nitrogen is getting oxidized.
  • Whereas removal of oxygen from [tex]H_2O_2[/tex] gives [tex]H_2O[/tex] gas which means that oxygen is getting reduced.
