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)

3 Ni + Fe(NO₃)₃ --> 3 Ni(NO₃) + Fe

Explanation:

In this question, the reactants are;

Solid Nickel and Iron nitrate. This is represented as;

Ni and Fe(NO3)3

The equation of the reaction is given as;

3 Ni + Fe(NO₃)₃ --> 3 Ni(NO₃) + Fe

The option that closely matches this is;

Option D. (Although the reaction is not balanced)
