Guys answer this question plz...

Answer 1

Since ammonium (NH4) has a charge of +1 then N + 4 H = +1, hydrogen has a +1 Ox# so then N + 4 = +1 which means that the nitrogen must be -3. Since nitrate (NO3) has a charge of -1 then N + 3 O = -1, oxygen has a -2 Ox# so then N + (-6) = -1 or N - 6 = -1 which means that this nitrogen must be +5.
