• acetate potassium sulfate and strontium iodide chromium (III)
• nitrate and sodium phosphate

<span>• sodium chloride and lead (II) acetate molecular equation. </span>Pb(CH3COO)2 + 2 NaCl = PbCl2 + 2 CH3COONa acetate potassium sulfate and strontium iodide chromium (III) molecular equationK2 SO4 (aq) + Sr I2 (aq) = 2 KI (aq) + Sr SO4 (s) • nitrate and sodium phosphate molecular equationCr(NO3)3 (aq) + Na3PO4 (aq) = 3 NaNO3 (aq) + CrPO4 (s)
Answer: 2NaCl + Pb(C2H3O2))2 ==> 2NaC2H3O2 + PbCl2
K2SO4 + SrT2 ==> 2KI + SrSO4
Cr(NO3)3 + Na3PO4 ==> 3NaNO3 + CrPO4
Explanation:
PbCl2 is precipitated and is insoluble in the solution.
SrSO4 is precipitated and is insoluble in the solution.
CrPO4 is precipitated and is insoluble in the solution.
