Solid nickel is added to aqueous iron nitrate. Using the metal activity series, which chemical equation reflects this reaction and its outcome? Question 5 options: A) 3Ni(NO3)2 (aq) + 2Fe (s) → NR B) Ni (s) + Fe(NO3)3 (aq) → NR C) 3Ni(NO3)2 (aq) + 2Fe (s) → 3Ni (s) + 2Fe(NO3)3 (aq) D) 3Ni (s) + 2Fe(NO3)3 (aq) → 3Ni(NO3)2 (aq) + 2Fe (s)
