giving the incomplete equation 2N2O5 (g) which set of products completes and balances the incomplete equarion

The complete question is as follows

Given the incomplete equation: 2 N2O5 (g) = => Which set of products completes and balances the incomplete equation?

A) 2 N2 (g) + 3 H2 (g)

B) 2 N2 (g) + 2 O2 (g)

C) 4 NO2 (g) + O2 (g)

D) 4 NO (g) + SO2 (g)

The correct option is C) 4NO2 (g) + O2 (g)

Explanation:

Note that the products should be NO2 and O2 since the reactant is entirely made up of N and O. option A is not correct as hydrogen cannot emerge as a product in this reaction. Matter can never be created or be destroyed bu can only change in a chemical reaction. Option D is not also correct for the same reason.

Option B is not correct since it did not balance the number of atoms of O and N in the reactant side of the equation.

The option C) 4NO2 (g) + O2 (g) is therefore the right option since it balances both the elements and the number of atoms of the elements present.
