Question

Which coefficients correctly balance the formula equation NH₄NO₂ → N₂ + H₂O?

a. 1, 2, 2
b. 1, 1, 2
c. 2, 1, 1
d. 2, 2, 2

Answer 1

The balanced chemical equation for the decomposition of ammonium nitrite is 1NH4NO2 → N2 + 2H2O, matching option a. 1, 2, 2. The option (A) is correct.

Step-by-step explanation:

The student's question pertains to balancing a chemical equation for the decomposition of ammonium nitrite (NH₄NO₂) into nitrogen gas (N₂) and water (H₂O). The balanced chemical equation for this reaction is 1NH₄NO₂ → N₂ + 2H₂O, which corresponds to 1, 2, 2 from the given choices.

During the balancing of equations, the number of atoms of each element on the reactant side should equal the number of atoms on the product side, which is achieved with the mentioned coefficients. Therefore, option (A) is correct.
