Ammonium carbonate and iron(iii) nitrate are combined, solid iron(iii) carbonate and a solution of ammonium nitrate are formed.
Vanyuwa [196]

Answer:

The net ionic equation is: 3CO₃²⁻(aq) + 2Fe³⁺(aq) → Fe₂(CO₃)₃(s).

Explanation:

  • For the mentioned reaction:
  • We have the Molecular reaction:

3(NH₄)₂CO₃(aq) + 2Fe(NO₃)₃(aq) → Fe₂(CO₃)₃(s) + 6NH₄NO₃(aq)

 

  • We have the total ionic reaction:

6NH₄⁺(aq) + 3CO₃²⁻(aq) + 2Fe³⁺(aq) + 6NO₃⁻ → Fe₂(CO₃)₃(s) + 6NH₄⁺(aq) + 6NO₃⁻(aq).

<em>NH₄⁺(aq) and NO₃⁻(aq) are spectator ions that are not changed through the reaction and still dissolved in the medium, so they can be omitted to get the net ionic equation.</em>

<em />

  • So, the net ionic equation is:

<em>3CO₃²⁻(aq) + 2Fe³⁺(aq) → Fe₂(CO₃)₃(s).</em>
