Derive the net ionic equation for the reaction between sodium alginate and cacl2

i’m having a hard time pls

2NaC₆H₇O₆ + CaCl₂ -> 2NaCl + Ca(C₆H₇O₆)₂

C₆H₇O₆⁻ + Cl⁻ -> Cl⁻ + C₆H₇O₆⁻

Explanation:

Here the reaction which is taking place is a double displacement reaction.

In this there is only an exchange of bonds and no chemical reaction.

Here the ions remain exactly the same

C₆H₇O₆⁻ + Cl⁻ -> Cl⁻ + C₆H₇O₆⁻

We can balance the skeletal equation

NaC₆H₇O₆ + CaCl₂ -> NaCl + Ca(C₆H₇O₆)₂

First we balance Chlorine atoms by writing 2NaCl

NaC₆H₇O₆ + CaCl₂ -> 2NaCl + Ca(C₆H₇O₆)₂

Now in order to balance Na atoms we make it 2NaC₆H₇O₆

2NaC₆H₇O₆ + CaCl₂ -> 2NaCl + Ca(C₆H₇O₆)₂

In this equation all atoms are balanced.
