Write balanced NET IONIC equations for the following double replacement reaction

Question

Write balanced NET IONIC equations for the following double replacement reactions that occur in water. Use the solubility chart rules to determine physical states. 1. K2SO4+BaCl2?>KCl+BaSO4 2.Al(NO3)3+NaOH?>Al(OH)3+NaNO3 3.CaCl2+Na2CO3?>NaCl+CaCO3 4.Na2S+Pb(C2H3O2)2?>PbS+NaC2H3O2 5.H2SO4+NaOH?>Na2SO4+H2O 6.Na2S+HCl?>H2S+NaCl 7.K2CO3+HNO3?>H2O+CO2+KNO3 8.(NH4)2SO4+Ba(NO3)2?>NH4NO3+BaSO4 9.Ba(OH)2+H3PO4?>H2O+Ba3(PO4)2

Explanation / Answer

1) Ba2+(aq) + SO4 2-(aq) ---> BaSO4, 2) Al3+ (aq) + 3OH- (aq) ---> Al(OH)3 , 3) Ca2+(aq) + CO3 2-(aq) ---> CaCO3, 4) Pb2+ + S2-(aq) ---> PbS, 5) H+(aq) + OH-(aq) ---> H2O, 6) 2H+ (aq) + s2-(aq) ---> H2S, 7) 2H+ + CO3- ---> H2O + CO2, 8) Ba2+ (aq) + SO4 2-(aq) ---> BaSO4, 9) 3Ba2+(aq) + PO4 3-(aq) ----> Ba3(PO4)2
