aqueous strontium sulfide
You would start by simply writing your reactants and products out, noting this is a double replacement reaction. BaCl2 + Li2SO4 -----> BaSO4 + LiCl Then you would need to go back and balance the equation. Note in the above that there are two chloride ions on the left but only one on the right. This can be balanced by placing a coefficient of 2 in front of LiCl. BaCl2 + Li2SO4 -----> BaSO4 + 2LiCl This is now a balanced equation.
This is not 'the balanced equation' of MgSO, what is meant is the chemical FORMULA of magnesium sulfate or magnesium sulfite.These are: MgSO4 and MgSO3respectively.
Barium sulphate to barium sulphate is NO CHANGE!
The chemical formula (not equation) of copper(II) sulfate is CuSO4.
Because strontium sulfate is much less soluble in water than strontium chloride, sodium chloride, or sodium sulfate, this reaction is: Na2SO4 (aq) + SrCl2 (aq) => 2 NaCl (aq) + SrSO4 (s).
K2SO4(aq) + SrI2(aq)=SrSO4(aq) + 2kI(aq)
BaCl2+K2SO4=2KCl+BaSO4
The balanced equation for sodium sulfate (Na2SO4) plus barium chloride (BaCl2) yielding barium sulfate (BaSO4) and sodium chloride (NaCl) is: Na2SO4 + BaCl2 -> BaSO4 + 2NaCl
BaSO4 + 2CaCl2 --> Ba(Cl2)2 + Ca2SO4
Na2SO4 +CaCl2---------------> 2NaCL +CaSo4
aqueous strontium sulfide
This equation is BaCl2 (aq) + Na2SO4 (aq) -> 2 NaCl (aq) + BaSO4 (s).

The BaSO4 (barium sulfate) will precipitate out of solution because it is insoluble, whereas the KCl2 is soluble and will remain dissolved. The balanced equation is: K2SO4 + BaCl2 -----> 2KCl + BaSO4
Ba2+ + [2Cl- + 2Na+] + SO42---> BaSO4 + [2Cl- + 2Na+]Ba2++ SO42- --> BaSO4
