Ag changes from zero to +1. N (in HNO3) changes from +5 to +2(in NO). Note that some of the NO3^- ions don't change at all.
i have all the oxidation numbers for all the of elements but i don't understand how i'm supposed to balance the equation using the oxidation numbers.
Do i have to to change the oxidation numbers to equation the same on each side?
