1. 1) Demonstration 2) Worksheet #14 3) Seminar is tomorrow: Tuesday, April 1st

3. Energy Stoichiometry Problem How much heat will be released when 1 mole of sulfur reacts with excess O 2 according to the following equation? 2 S + 3 O 2 → 2 SO 3 ∆H = -791.4 kJ

4. List about Chemical Reactions and Energy 1) Endothermic 6) Temp. 2) Exothermic 7) Coefficients 3) Potential and Kinetic 8) Units 4) Forming bonds 9) Releasing 5) Joules(kilo)10) Breaking bonds

5. Is the reaction below an endothermic or exothermic reaction? 2 S + 3 O 2 → 2 SO 3 ∆H = -791.4 kJ
