Question

The decomposition of dinitrogen tetraoxide 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)

Answer 1

Its c) N2O4(g) to N2(g)+2O2(g).Honestly, I don't know why but I got it right on my test.

Answer 2

Answer : The correct option is, (C)
`N_2O_4(g)\rightarrow N_2(g)+2O_2(g)`

Explanation :

Decomposition reaction : It is a type of reaction in which a single compound decomposes into two or more new compounds.

The decomposition of dinitrogen tetraoxide into nitrogen gas and oxygen gas is shown by balanced chemical equation.

The balanced decomposition reaction will be,

`N_2O_4(g)\rightarrow N_2(g)+2O_2(g)`

By the stoichiometry, 1 mole of dinitrogen tetraoxide decomposes into 1 mole of nitrogen gas and 2 moles of oxygen gas.

Hence, the correct option is, (C)
