Energetics

Energetics is the study of the energy changes involved in chemical reactions. We can measure these changes and draw conclusions about the nature of particular reactions and relate them to the energy contained within individual bonds. We will find that some reactions gain energy while others lose energy and we will learn how to predict this difference and investigate our predictions in the laboratory.



__**Endothermic and Exothermic Reactions**__

Reactions involve energy transfers. Some absorb energy (endothermic) and some release energy (exothermic).

__**Calorimetry**__

Go to [|www.explorelearning.com] and work through the simulation on "Calorimetry". This simulates the measurement of energy transformations. Complete this sheet: Enthalpy Lab Simulations
