  1. Single Displacement Reactions SCH3U

  2. Single Displacement Reaction • One element takes the place of another element in a compound. B AX A BX + +  +  + Fe2O3 (s) + 2 Al (s)  Al2O3(s) + 2 Fe (s)

  3. Types of Single Displacement Rxns • A metal displaces another metal from an ionic compound • Cu (s) + 2 AgNO3 (aq)  Cu(No3)2 (aq) + 2 Ag (s) • What about… • Ag (s) + Cu(NO3)2 (aq) 

  4. The Activity Series Displaces hydrogen from cold water Displaces hydrogen from acids

  5. Types of Single Displacement Rxns • A metal displaces another metal from an ionic compound • Cu (s) + 2 AgNO3 (aq)  Cu(No3)2 (aq) + 2 Ag (s) • What about… • Ag (s) + Cu(NO3)2 (aq)  NR

  6. Types of Single Displacement Rxns • A metal displaces hydrogen from acid • Mg (s) + 2 HCl (aq)  MgCl2 (aq) + H2 (g) • Think of the acid as ions. • Metal displaces the hydrogen and forms an ionic compound with the chloride ions. • A metal displaces hydrogen from water • 2 Na (s) + 2 H2O (l)  2 NaOH (aq) + H2 (g)

  7. Types of Single Displacement Rxns • A non-metal displaces another non-metal from an ionic compound • Diatomic halogen + ionic compound with a halogen  might have a reaction. • Cl2 (g) + 2 NaBr (aq)  2 NaCl (aq) + Br2 (l)
