Question

Write the net ionic equation, including phases, that corresponds to the reactionFe(NO3)₂(aq) + Na₂CO3(aq) -----> FeCO3(s) + 2 NaNO3(aq)

Answer 1

`Fe^(2+)(aq)+CO_3^(2-)\left(aq\right)\rightarrow FeCO_3\left(s\right)`

Step-by-step explanation

The given equation is:

`Fe\left(NO_3\right)_2\left(aq\right)+Na_2CO_3\left(aq\right)\rightarrow FeCO_3\left(s\right)+2NaNO_3\left(aq\right)`

What to find:

To write the net ionic equation, including phases, that corresponds to the given reaction.

Step-by-step solution:

Going through the given equation, the equation is balanced molecularly. and the phases indicated.

The next step is split the electrolytes into ions (that is, to write the complete ionic equation).

`Fe^(2+)(aq)+2NO_3^-\left(aq\right)+2Na^+(aq)+CO_3^(2-)\left(aq\right)\rightarrow FeCO_3\left(s\right)+2Na^+(aq)+NO_3^(2-)\left(aq\right)`

Cross the spectator ions on both sides of the complete ionic equation. (Spectator ions are ions that are unchanged on both sides of the complete equation).

Hence, the net ionic equation, including phases, that corresponds to the reaction given will be:

`Fe^(2+)(aq)+CO_3^(2-)\left(aq\right)\rightarrow FeCO_3\left(s\right)`
