What Is the Equation for the Formation Reaction for Gaseous

Multiple Choice

What is the equation for the formation reaction for gaseous hydrazine, N₂H₄, at 25ºC and 1 atm pressure?

A) 2N₂H₄(g) → 2NH₃(g) + H₂(g)
B) 2NH₃(g) + H₂(g) → N₂H₄(g)
C) N₂(g) + 2H₂O(g) → N₂H₄ (g) + O₂(g)
D) N₂(g) +2H₂(g) → N₂H₄(g)
E) 2NO₂(g) + 6H₂(g) → N₂H₄(g) + 4H₂O(g)
