write the net ionic equation (including phases) that corresponds to zn(no3)2 + Na2CO3--->ZnCO3+2NaNO3
To write the net ionic equation, we first need to write the balanced chemical equation for the given reaction.
The balanced equation for the reaction between Zn(NO3)2 and Na2CO3 is:
Zn(NO3)2 + Na2CO3 → ZnCO3 + 2NaNO3
To write the net ionic equation, we need to identify the species that are present as ions both before and after the reaction, and omit the spectator ions (ions that do not participate in the reaction).
In this case, only Zn2+, CO32-, and Na+ ions are involved in the reaction. The nitrate (NO3-) ions and sodium (Na+) ions do not change during the reaction and are considered as spectator ions.
The net ionic equation is obtained by omitting the spectator ions:
Zn2+(aq) + CO32-(aq) → ZnCO3(s)
Note that "(aq)" represents species in aqueous solution and "(s)" represents a solid precipitate.
So, the net ionic equation for the reaction Zn(NO3)2 + Na2CO3 → ZnCO3 + 2NaNO3 is:
Zn2+(aq) + CO32-(aq) → ZnCO3(s)
