  1. Chemistry Week 29 Please get out your notebooks!

  2. April 1, 2013 AGENDA: 1 – Bell Ringer & Agenda 2 – CN: Energy in Chemical Reactions 3 – Work Time: Exothermic & Endothermic Reactions 4 – Summary (Critical Thinking Problem) Today’s Goal: Students will be able to define energy and heat and contrast exothermic and endothermic reactions. Homework • Exothermic & Endothermic Reactions – due tomorrow • Binder Check – by tomorrow!! After that…it will only be worth 60% credit.

  3. Monday, April 1st Objective: Students will be able to define energy and heat and contrast exothermic and endothermic reactions. Bell Ringer: If you are participating in a high energy activity, describe what happens to your body during the activity.

  4. 30 seconds Remaining…

  7. Cornell Notes • Topic: Energy in Chemical Reactions (Exothermic vs. Endothermic) • Date:4/01/2013 • Energy is the ability to do work or produce heat. • Kinetic energy = energy of movement • Potential energy = energy of position • Chemical energy = energy of chemical reactions Describe energy.

  8. Cornell Notes (continued) • Heat (q) = energy that transfers from one object (or place) to another because of a temperature difference between the objects. Units of heat energy = Joules (J) or kilojoules (kJ = 1000J) • Heat always moves from objects/places with higher heat to objects/places with lower heat. What is heat?

  9. Cornell Notes (continued) • Chemical potential energy is the energy stored in the reactants of a chemical reaction. • Measuring energy: Universe = Surroundings + System Surroundings Surroundings System Heat Heat EndothermicExothermic Explain chemical potential energy. q =(+) q =(-)

  10. Cornell Notes (continued) Compare and contrast exothermic and endothermic reactions.
