In this activity you will investigate several displacement reactions of a metal with silver nitrate solution, and measure the temperature change. You will learn how the temperature change is related to the metal's position in the reactivity series, and that it is a result of bond-breaking and bond-formation.

This item teaches:

• about the balance between bonds formed and broken in an exothermic reaction
• how mean bond enthalpies can be used to calculate the enthalpy change for a reaction
• about the use of bond energies to calculate the energy transferred in reactions
• about the balance between bonds formed and broken in an endothermic reaction
• about the reactivity series
