2Na+(aq) + 2OH−(aq) + Zn2+(aq) + 2NO3−(aq) → Zn(OH)2(s) + 2Na+(aq) + 2NO3−(aq)

Write the net ionic equation for this precipitation reaction.

You have written the complete ionic equation. To turn this into the net ionic equation just do this. Cancel the ions that appear on both sides. What's left is the net ionic equation.

2Na^+ are on both sides. Cancel.
2NO3^- are on both sides. Cancel.
Zn^2+(aq) + 2OH^-(aq) ==> Zn(OH)2(s) is what's left.

To write the net ionic equation for this precipitation reaction, we need to first write the balanced complete ionic equation, and then eliminate the spectator ions to get the net ionic equation.

1. Start by writing the balanced complete ionic equation:
2Na+(aq) + 2OH−(aq) + Zn2+(aq) + 2NO3−(aq) → Zn(OH)2(s) + 2Na+(aq) + 2NO3−(aq)

2. Identify the spectator ions, which are ions that appear on both sides of the equation and do not participate in the reaction. In this case, Na+ and NO3− are spectator ions because they are present on both sides of the equation.

3. Eliminate the spectator ions from the equation:
2OH−(aq) + Zn2+(aq) → Zn(OH)2(s)

4. This is the net ionic equation for the precipitation reaction:
2OH−(aq) + Zn2+(aq) → Zn(OH)2(s)

The net ionic equation represents the reaction without the spectator ions, focusing only on the species that are actually involved in the reaction.

To write the net ionic equation for this precipitation reaction, we need to first write the balanced molecular equation.

The given balanced molecular equation is:
2Na+(aq) + 2OH−(aq) + Zn2+(aq) + 2NO3−(aq) → Zn(OH)2(s) + 2Na+(aq) + 2NO3−(aq)

To write the net ionic equation, we need to eliminate the spectator ions, which are the ions that appear on both sides of the equation and do not undergo any change during the reaction.

The spectator ions in this reaction are the Na+ and NO3− ions.

The net ionic equation is obtained by removing the spectator ions from the balanced molecular equation:

Net ionic equation:
2OH−(aq) + Zn2+(aq) → Zn(OH)2(s)

Therefore, the net ionic equation for this precipitation reaction is 2OH−(aq) + Zn2+(aq) → Zn(OH)2(s).
