Consider the balanced equation below.
Alexus [3.1K]

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
