#N_2O_5(g) rarr 2NO_2(g) + 1/2O_2(g)#

Explanation:

Can I have 1/2 a molecule of #O_2(g)#? How do I get rid of the #1/2# coefficient? Is this a redox reaction?

#"2N"_2"O"_5##rarr##"4NO"_2+"O"_2#

Explanation:

#"N"_2"O"_5##rarr##"NO"_2+"O"_2#

Add coefficients in front of the formulas in order to balance the equation.

#"2N"_2"O"_5##rarr##"4NO"_2+"O"_2#

There are now 4 atoms of N and 10 atoms of oxygen on both sides, and the equation is balanced.
