Question

Hydrazine (N2H4) and dinitrogen tetroxide (N2O4) form a self-igniting mixture that has been used as a rocket propellant. The reaction products are N2 and H2O. Part A Write a balanced chemical equation for this reaction. Express your answer as a chemical equation. nothing A chemical reaction does not occur for this question. Request Answer Part B What is being oxidized, and what is being reduced

Answer 1

2N₂H₄+N₂O₄→3N₂+4H₂O; N₂H₄ gets oxidized, N₂O₄ gets reduced.

Step-by-step explanation:

Part A

They tell us what substances react to form what products, so we can write an unbalanced chemical equation from those substances.

N₂H₄+N₂O₄→N₂+H₂O

To balance this equation, we need to make it so there is an even amount of each element on both sides of the reaction. We can do this by multiplying the amount of each substance by adding a coefficient in front of it.

2N₂H₄+N₂O₄→3N₂+4H₂O

Part B

To identify what is being oxidized and what is being reduced, look at the oxidation charges of each element.

N₂H₄ gets oxidized, N₂O₄ gets reduced.
