Answer:
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.
