Answer:
The answer to your question is below
Explanation:
In a double displacement reaction, the cations interchange between the two reactants.
Na₃PO₄ + CuSO₄ ⇒ Na₂SO₄ + Cu₃(PO₄)₂
Now, we need to balance the equation
Na₃PO₄ + CuSO₄ ⇒ Na₂SO₄ + Cu₃(PO₄)₂

3 Na 2
1 P 2
1 Cu 1
1 S 1
8 O 12
This reaction is unbalanced so we need to balance it.
2Na₃PO₄ + 3CuSO₄ ⇒ 3Na₂SO₄ + Cu₃(PO₄)₂

6 Na 6
2 P 2
3 Cu 3
3 S 3
20 O 20
Now the equation is balanced
