Question

the decomposition of dinitrogen tetroxide into nitrogen gas and oxygen gas is shown by which balanced chemical equation? a n₂(g) + 2o₂(g) → n₂o₄(g) b n₂o₄(g) → n₂(g) + o₂(g) c n₂o₄(g) → n₂(g) + 2o₂(g) d n₂o₄(g) + 2o₂(g) → n₂(g)

Explanation:

Step1: Recall decomposition concept

Decomposition is a reaction where a single compound breaks down into two or more simpler substances. For the decomposition of dinitrogen tetroxide ($N_2O_4$) into nitrogen gas ($N_2$) and oxygen gas ($O_2$), the reactant is $N_2O_4$ and products are $N_2$ and $O_2$.

Step2: Check balanced equation

The balanced chemical equation for the decomposition of dinitrogen - tetroxide is $N_2O_4(g)
ightarrow N_2(g)+2O_2(g)$.

Answer:

B. $N_2O_4(g)
ightarrow N_2(g)+2O_2(g)$
