INFORMATION:
We have the next reaction:
- Mg(NO3)2 + Na2CO3
And we must find its net ionic equation
STEP BY STEP EXPLANATION:
To find the net ionic equation, we must follow the next steps
1. We must write the balanced equation
[tex]Mg(NO_3)_2+Na_2CO_3→MgCO_3+2NaNO_3[/tex]
2. We must write the states
[tex]Mg(NO_3)_2\text{ \lparen aq\rparen }+Na_2CO_3\text{ \lparen aq\rparen }→MgCO_3\text{ \lparen s\rparen }+2NaNO_3\text{ \lparen aq\rparen }[/tex]
3. We must split strong electrolytes into ions
[tex]Mg^{2+}+2NO_3^-+2Na^++CO_3^{2-}→MgCO_3+2Na^++2NO_3^-[/tex]
4. We must cross out the spectator ions on both sides
5. Finally, we must write the remaining substances
[tex]Mg^{2+}\text{ \lparen aq\rparen }+CO_3^{2-}\text{ \lparen aq\rparen }→MgCO_3\text{ \lparen s\rparen }[/tex]
ANSWER:
The net ionic equation for Mg(NO3)2 + Na2CO3 is:
