#### Explanation:

Two things come in handy here

for a neutral compound, the sum of the oxidation numbers of all constituent atomsmust beequal tozerothe oxidation number of oxygen is usually equal to#-2#

This means that if you take

#color(blue)(2) xx ? + color(red)(5) xx (-2) = 0#

All you have to do now is solve for

#color(blue)(2) xx ? = +10 implies ? = (+10)/2 = +5#

And there you have it, nitrogen has a
