CuCl2(aq) + NaOH(aq) right-arrow Cu(OH)2(s) + NaCl(aq) what is the ionic equation and net ionic equation ?

Reactions are given below.

Explanation:

Chemical equation:

CuCl₂ + NaOH     →    Cu(OH)₂ + NaCl

Balanced Chemical equation:

CuCl₂(aq) + 2NaOH(aq)     →    Cu(OH)₂(s) + 2NaCl(aq)

Ionic equation:

Cu²⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + 2OH⁻(aq) →  Cu(OH)₂(s) + 2Na⁺(aq) + 2Cl⁻ (aq)

Net ionic equation:

H⁺(aq) + OH⁻(aq) → H₂O(l)  

The Cl⁻(aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The Cu(OH)₂ can not be splitted into ions because it is present in solid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
