April 16, 2012 AGENDA: 1 – Bell Ringer & Part. Log 2 – CN: Energy in Chemical Reactions 3 – Work Time: Exothermic & Endothermic Reactions Today’s Goal: Students will be able to contrast exothermic and endothermic reactions. Homework • Exothermic & Endothermic Reactions • Extra Credit Work from WEEK 30is due Friday
Cornell Notes • Topic: Energy in Chemical Reactions (Exothermic vs. Endothermic) • Date: 4/16/2012 • 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.
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.
Cornell Notes (continued) Compare and contrast exothermic and endothermic reactions.
