Question

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!!!!

Answer 1

3CuCl₂ + 2Na₃PO₄ → Cu₃(PO₄)₂ + 6NaCl

Step-by-step 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
