i need help writing molecular equation ... please

2. Write the molecular equations for the following double displacement reactions: Use the solubility table in Appendix 2 for reactions that were not observed directly in this experiment. (a) Sodium bromide and silver nitrate. (b) Sodium carbonate and silver nitrate. (c) Sodium arsenate and barium chloride. (d) Sodium iodide and lead (II) nitrate. (e) Sodium phosphate and iron (III) bromide. (f) Sodium phosphate and barium chloride. (g) Sodium sulfate and barium chloride

Explanation / Answer

a) AgNO3 (aq) + NaBr (aq) ? AgBr (s) + NaNO3 (aq)

b)Na2CO3(aq) + 2 AgNO3(aq) --> Ag2CO3(s) + 2 NaNO3(aq)

c)2Na3AsO4(aq) + 3BaCl2(aq) --> Ba3(AsO4)2(s) + 6NaCl(aq)

d)Pb(NO3)2(s) + 2NaI(aq) ? 2PbI2(s) + 2NaNO3(aq)

e)FeBr3 + Na3PO4 --> FePO4 + 3 NaBr

f)2Na3PO4 (aq) + 3BaCl2(aq) --> 6NaCl(aq) + Ba3(PO4)2 (s)

g)BaCl2(aq)+Na2SO4(aq)?BaSO4(s)??+2NaCl(aq)
