Provided here is an unbalanced chemical equation. CuCl2 + Na3PO4 Cu3(PO4)2 + NaCl
Which of the following shows the product side of the correctly balanced equation?
please help

3CuCl₂   +    2Na₃PO₄  →   Cu₃(PO₄)₂   +  6NaCl

Explanation:

The reaction expression is given as:

   CuCl₂   +    Na₃PO₄  →   Cu₃(PO₄)₂   +  NaCl

To balance this expression, let us assign coefficients a, b, c and d;

     aCuCl₂   +    bNa₃PO₄  →   cCu₃(PO₄)₂   +  dNaCl

Conserving Cu: a  = 3c

                    Cl:  2a = d

                    Na:  3b = d

                     P:   b  = 2c

                    O:  4b  = 8c

let as  c = 1, a  = 3, d  = 6 , b  = 2

        3CuCl₂   +    2Na₃PO₄  →   Cu₃(PO₄)₂   +  6NaCl

b i think it’s a water wheel turning in a stream
