Question

N2H4 + 2H2O2 mc005-1.jpg N2 + 4H2O What are the mole ratios of hydrazine (N2H4) to hydrogen peroxide (H2O2) and hydrazine to water

Answer 1

1 N₂H₄ + 2 H₂O₂ = 1 N₂ + 4 H₂O

The mole ratio between hydrazine and hydrogen peroxide is 1 : 2

The mole ratio between hydrazine and water is 1 : 4

hope this helps!

Answer 2

Answer : The mole ratio of
`N_2H_4:H_2O_2` is, 1 : 2 and the mole ratio of
`N_2H_4:H_2O` is, 1 : 4

Explanation :

As we are given the balanced chemical reaction. Now we have to determine the mole ratio of hydrazine to hydrogen peroxide and hydrazine to water.

The given balanced chemical reaction is,

`N_2H_4+2H_2O_2\rightarrow N_2+4H_2O`

By the stoichiometry we can say that, 1 mole of hydrazine
`(N_2H_4)` react with 2 moles of hydrogen peroxide
`(H_2O_2)` to give 1 mole of nitrogen gas
`(N_2)` and 4 moles of water
`(H_2O)`.

From this we conclude that,

The mole ratio of
`N_2H_4:H_2O_2` is, 1 : 2

The mole ratio of
`N_2H_4:H_2O` is, 1 : 4

Therefore, the mole ratio of
`N_2H_4:H_2O_2` is, 1 : 2 and the mole ratio of
`N_2H_4:H_2O` is, 1 : 4
