Predicting Products

Single Displacement Use activity series A more active element replaces a less active one or the reaction will not occur

NaCl + F2 ---> NaF + Cl2 NaF + Cl2 ---> No reaction

MgCl2 + Na  KBr + Cl2  FeCl3 + Cu  Na2SO4 + Cu 

Double Displacement or Metathesis Use solubility tables For a reaction to occur, a ppt must form

BaCl2(aq)+ K2SO4(aq) -----> BaSO4(s)+ KCl(aq)

NaCl(aq) + KBr(aq) -----> NaBr(aq) + KCl(aq) No Reaction

Name reactants, predict & name products, and balance & classify the reactions on the board

DD or Metathesis Acid-base: When an acid is combined with a base, the products will be salt & water

HCl(aq) + NaOH(aq) -----> NaCl(aq) + H2O(l)

Mg(OH)2(aq) + H2SO4(aq)  MgSO4(aq) + H2O(l)

Ba(OH)2(aq) + CaCl2(aq) ZnCl2(aq) + K2CrO4(aq) KCl(aq) + Na2SO4(aq)

HCl(aq) + NaOH(aq) H2SO4(aq) + KOH(aq) HCl(aq) + NH3(aq)

Carbon compound + oxygen yields Carbon dioxide & water Combustion Carbon compound + oxygen yields Carbon dioxide & water

C3H6(g) + O2(g) C4H8O(l) + O2(g) C4H8O4(g) + O2(g)

Predict Products & Balance Rxn CaCl2 + F2  CaCl2 + Na  CaCl2 + KNO3  CaCl2 + K2SO4 

Predict & Balance AlBr3 + F2  AlBr3 + Zn  AlBr3 + Na  AlBr3 + Ba(NO3)2  AlBr3 + K2SO4 
