Chemistry Honors – Class 46

Exothermic Reaction (your grade?)

Dates

• Periods B, D: Tuesday, December 2nd
• Period G: Wednesday, December 3rd

Energy of Reactions

• Calorimetry is used to determine DH (kind of like the Peanut Lab)
• chemical reaction in solution produces heat change
• EXAMPLE – problem #66 (p. 288)

Definition of Terms

• molar heat of reaction
• “train tracks – mass to energy”
• heat of reaction causing temperature rise
• example (NaOH + HCl –> H2O + NaCl)

Textbook Section (read + notes for exam)

• 6.1 – Nature of Energy (246 – 248)
• 6.2 – Enthalpy and Calorimetry (254 – 259)
• 6.5 – Present Sources of Energy (overview)
