Question

Hydrazine (N2H4), a rocket fuel , reacts with oxygen to form nitrogen gas and water vapor. The reaction is represented with the equation: N2H4(l) + O2(

g. → N2(
g. + 2H2O(
g. If 6 moles of hydrazine react with an excess of oxygen, how many moles of water will be produced?

Answer 1

Answer is: 12 moles of water will be produced.
Balanced chemical reaction: N₂H₄ + O₂ → N₂ + 2H₂O.
n(N₂H₄) = 6 mol.
From balanced chemical reaction: n(N₂H₄) : n(H₂O) = 1 : 2.
n(H₂O) = 2 · n(N₂H₄).
n(H₂O) = 2 · 6 mol.
n(H₂O) = 12 mol.
n - amount of substance.
