Write a balanced chemical equation for the following acid-base reaction:
Bromic acid reacting with hydrazine (N2H4).
A
HBrO3 (aq) + N2H4 (aq) → N2H5BrO3 (aq)
B
HBrO4 (aq) + N2H4 (aq) → N2H5BrO4 (aq)
C
HBrO3 (aq) + N2H4 (aq) → H2BrO3 (aq) + N2H3– (aq)
D
HBrO4 (aq) + N2H4 (aq) → BrO4– (aq) + N2H4+ (aq)
Verified step by step guidance1
Identify the reactants and products in the given chemical reaction. The reactants are bromic acid (HBrO3) and hydrazine (N2H4).
Determine the possible products of the reaction. In an acid-base reaction, the acid donates a proton (H+) to the base. Consider the possible products based on proton transfer.
Write the unbalanced chemical equation using the identified reactants and products. For example, one possible reaction could be: HBrO3 (aq) + N2H4 (aq) → N2H5BrO3 (aq).
Balance the chemical equation by ensuring that the number of atoms of each element is the same on both sides of the equation. Adjust the coefficients of the reactants and products as necessary.
Verify that the charges are balanced on both sides of the equation, ensuring that the overall charge is the same for both reactants and products. This confirms that the equation is correctly balanced.
