DAY 26, Specific outcomes and skills that may be tested on exam 4:

Sections 10.1-10.4

  • Be able to describe potential energy changes for the system, kinetic energy and temperature changes for the surroundings, and bond stability changes for the system in any endothermic or exothermic system.
  • Given either change in energy for the system or surroundings, be able to calculate the other
  • Given two out of three of any of the following quantities, be able to calculate the third: change in heat for the system, change in work for the system, overall change in energy for the system
  • Given initial heat and final heat, be able to calculate the change in enthalpy for a system
  • Be able to determine whether a process is endo or exothermic based on the mathematical sign for the change in enthalpy
  • Be able to calculate how the enthalpy change will be different if a chemical equation is reversed or multiplied by a certain stoichiometric coefficient
  • Given two of the following quantities, be able to calculate the third: temperature change, heat change, heat capacity
  • Given three of the following quantities, be able to calculate the fourth: temperature change, heat change, mass, specific heat
  • Be able to describe how to set up a coffee cup or bomb calorimeter to calculate changes in energy based on measured changes in temperature and energy exchanges between system and surroundings

Complete these problems outside of class until you are confident you have learned the SKILLS in this section outlined on the study guide and we will review some of them next class period.  10.5  10.7  10.11  10.13  10.23  10.27  VC10.3  VC10.8  10.31  10.35  10.37  10.41  10.97  10.115  10.121
