Here's a breakdown:

* N₂H₈: This part represents hydrazine, a colorless, flammable liquid with the formula N₂H₄. It's a highly reactive compound often used as a rocket propellant.

* SO₄: This part represents sulfate, a polyatomic ion with the formula SO₄²⁻.

Therefore, N₂H₈SO₄ is the chemical formula for hydrazine sulfate, a salt formed by the reaction of hydrazine with sulfuric acid.
