Question

Hydrazine (N2H4) and hydrogen peroxide (H2O2) have been used as rocket propellants. They react according to the following equation:

7H2O2 + N2H4 ? 2HNO3 + 8H2O

a) When 68 kg of hydrazine react, how many grams of nitric acid can be formed?

Hydrazine (N2H4) and hydrogen peroxide (H2O2) have been used as rocket propellants. They react according to the following equation: 7H2O2 + N2H4 ? 2HNO3 + 8H2O When 68 kg of hydrazine react, how many grams of nitric acid can be formed? When 460 mL of hydrogen peroxide (d = 1.41 g/mL) react, how many grams of water can be formed? How many grams of hydrazine will be required to react with 432 g hydrogen peroxide? How many grams of water can be produced when 237 g hydrazine combine with 198 g hydrogen peroxide? How many grams of the excess reactant in part (d) are left unreacted?

Explanation / Answer

7H2O2 + N2H4 ? 2HNO3 + 8H2O

a. mass of HNO3 formed=268.8175 kg

b.mass of water formed = 392.43 grams

c.mass of hydrazine required= 58.08grams

d. H2O2 is the limiting reagent mass of water produced= 119.8 grams

e. excess hydrazine = 210.28 grams
