Answer 1

3 Aqueas Solutions oSodium phosphate and Silver Combine ts yield Sodium nitrat and nithata Silver phosphate a) To unita mdlecular equation, shoo the chemical formulae all ruactants and produets (Sodium (silver nitrale) (aq) (sodiu Ser \nitrate phosphat Ca phasphat) >NaNo AgP Coa) .+ AgNo3 Na Po Cag) S) To balance the above, the Co-officients are changed as NasP 3AgNO Ca) 3 NaN03 t Ag Pa, Caey the above balaned equatioo is mdecular equatioo for the eaetion b) To wri t the total ionic equation for the above, disociate the Compoumds into lons , which are Solulble in water. The Compounds whith are nsduble in wate amd remained ay solid with ther moecular formula Should be indicated Only 3Nat P 3Na+3N 3Ağt3 NO Cag cafy a) (aa) Ag Pa is solid Which is nsoluble in wate The above is the Total ionic equatzon (ag) ag)
