write the net ionic equation between of the reaction between MgCl2 and Na2SO4

First, let's write out the balanced chemical equation for the reaction between MgCl2 and Na2SO4:

MgCl2 + Na2SO4 -> MgSO4 + 2NaCl

Now, let's separate the strong electrolytes into their respective ions:

Mg2+ + 2Cl- + 2Na+ + SO4^2- -> MgSO4 + 2Na+ + 2Cl-

Next, we can cancel out the spectator ions (ions that appear on both sides of the equation):

Mg2+ + SO4^2- -> MgSO4

Therefore, the net ionic equation for the reaction between MgCl2 and Na2SO4 is:

Mg2+ + SO4^2- -> MgSO4
