Multiple Choice

Write a balanced chemical equation for the following acid-base reaction:
Bromic acid reacting with hydrazine (N₂H₄).

HBrO₃ (aq) + N₂H₄ (aq) → N₂H₅BrO₃ (aq)

HBrO4 (aq) + N2H4 (aq) → N₂H₅BrO₄ (aq)

HBrO3 (aq) + N2H4 (aq) → H₂BrO₃ (aq) + N₂H₃^– (aq)

HBrO₄ (aq) + N₂H₄ (aq) → BrO₄^– (aq) + N₂H₄⁺ (aq)

Verified step by step guidance

Identify the reactants and products involved in the acid-base reaction. Here, the reactants are bromic acid (HBrO3) and hydrazine (N2H4).

Understand the nature of the reaction: Bromic acid is an acid, and hydrazine is a base. In an acid-base reaction, the acid donates a proton (H+) to the base.

Write the unbalanced chemical equation using the chemical formulas of the reactants and products. Start with: HBrO3 (aq) + N2H4 (aq) → products.

Determine the products formed: In acid-base reactions, the base typically gains a proton from the acid. Consider possible products such as N2H5BrO3 or N2H5BrO4, where hydrazine gains a proton.

Balance the chemical equation: Ensure that the number of atoms of each element is equal on both sides of the equation. Adjust coefficients as necessary to achieve a balanced equation.
