Question

Consider the balanced equation below.

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

Answer : The mole ratios of Hydrazine to Hydrogen peroxide is 1 : 2 and

the mole ratios of Hydrazine to water is 1 : 4.

Explanation :

The balanced chemical equation is,

`N_(2)H_(4)+2H_(2)O_(2)\rightarrow N_(2)+4H_(2)O`

According to the given reaction,

1 mole of Hydrazine react with the 2 moles of Hydrogen peroxide.

Therefore, the mole ratios of Hydrazine to Hydrogen peroxide is 1 : 2

And in case of Hydrazine and water,

1 mole of Hydrazine gives 4 moles of water.

Therefore, the mole ratios of Hydrazine to water is 1 : 4

Answer 2

The mole ratio of Hydrazine to hydrogen peroxide is 1:2 and the mole ratio of Hydrazine to water is 1:4
