create a balanced reaction for the double displacement reaction between sodium phosphate na₃(po₄) and copper sulfate cu(so₄)

you will have to balance the ion ratios of the products as well as the over-all reaction for full points.

here are some ion charges that may you balance the products:

ion charges: (zn²⁺, cu²⁺, so₄²⁻, al³⁺, ag¹⁺, no₃¹⁻, cl¹⁻, oh¹⁻, po₄³⁻, na¹⁺)

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

              Reactants               Elements             Products

                     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

               Reactants               Elements             Products

                     6                             Na                      6

                      2                             P                         2

                      3                           Cu                        3

                      3                              S                         3

                    20                            O                       20

Now the equation is balanced

hope this !

explanation:

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
