Answer

Explanation:

Step1: Write the balanced molecular equation

Sodium carbonate ($Na_2CO_3$) reacts with iron (II) nitrate ($Fe(NO_3)_2$) to form sodium nitrate ($NaNO_3$) and iron (II) carbonate ($FeCO_3$). The molecular equation is $Na_2CO_3(aq)+Fe(NO_3)_2(aq)\rightarrow 2NaNO_3(aq)+FeCO_3(s)$.

Step2: Write the complete ionic equation

Break all aqueous - soluble compounds into ions. $2Na^+(aq)+CO_3^{2 - }(aq)+Fe^{2+}(aq)+2NO_3^-(aq)\rightarrow 2Na^+(aq)+2NO_3^-(aq)+FeCO_3(s)$.

Step3: Write the net ionic equation

Cancel out the spectator ions ($Na^+$ and $NO_3^-$). The net ionic equation is $Fe^{2+}(aq)+CO_3^{2 - }(aq)\rightarrow FeCO_3(s)$.

Answer:

$Fe^{2+}(aq)+CO_3^{2 - }(aq)\rightarrow FeCO_3(s)$
