Question

Ionic equation for Mg(NO3)2 + Na2CO3

Answer 1

The ionic equation is the one that expresses both reactants and products as ions when they are dissociated in aqueous solutions.

In this case we have the following chemical reaction:

`Mg(NO_3)_2(aq)+Na_2CO_3(aq)\rightarrow MgCO_3(s)+2NaNO_3(aq)`

So the ionic equation is the following:

`Mg^(+2)+2NO_3^-+2Na^++CO_3^(-2)\rightarrow MgCO_3+2Na^++2NO_3^-`

As we can see magnesium carbonate is not an ion in aqueous solution so it is not expressed as one,
