For the following aqueous reaction, complete and balance the molecular equation and write a net iconic equatio, making sure to include the physical states of the compounds:

Potassium carbonate + Strontium nitrate

Balance molecular equation:

K2CO3 (aq) + Sr (NO3) 2 (aq) → SrCO3 (s) + 2KNO3 (aq)

Net ionic equation:

CO3∧-2 (aq) + Sr∧+2 (aq) → SrCO3 (s)

Explanation:

Potassium carbonate = K2CO3

Strontium nitrate = Sr (NO3) 2

Chemical equation:

K2CO3 + Sr (NO3) 2 → SrCO3 + KNO3

Balance chemical equation with physical states:

K2CO3 (aq) + Sr (NO3) 2 (aq) → SrCO3 (s) + 2KNO3 (aq)

Ionic equation:

2K + (aq) + CO3∧-2 (aq) + Sr∧+2 (aq) + 2NO∧-3 (aq) → SrCO3 (s) + 2K + (aq) + 2NO∧-3 (aq)

Net ionic equation:

CO3∧-2 (aq) + Sr∧+2 (aq) → SrCO3 (s)

2K + and 2NO∧-3 ions are spectator ions that's way these are not written in net ionic equation.

Spectator ions:

These are the ions that are present same on both side of chemical reaction and does not effect the equilibrium.
