Module 9: Chapter 9: Thermochemistry Discussion
This discussion aligns with the following Module 9: Chapter 9: Thermochemistry objectives:
- Define energy, distinguish types of energy, and describe the nature of energy changes that accompany chemical and physical changes (CLO1)
- Distinguish the related properties of heat, thermal energy, and temperature (CLO1)(CLO3)
- Define and distinguish specific heat and heat capacity, and describe the physical implications of both (CLO1)
Calorimetry (9.2)
- Explain the technique of calorimetry (CLO1)
Enthalpy (9.3)
- State the first law of thermodynamics (CLO1)
- Define enthalpy and explain its classification as a state function (CLO1)
- Explain Hess’s law and use it to compute reaction enthalpies (CLO1)(CLO2)
Strengths of Ionic and Covalent Bonds (9.4)
- Describe the energetics of covalent and ionic bond formation and breakage (CLO1)

Be sure to comment on at least two of your classmates' postings. Your response should be at least 5 sentences long. This includes responses to classmates' posts. Your replies must be more than a simple phrase like "I agree" or "I like your answers". Replies should reflect why you agree or like what has been posted. Your replies must reflect a genuine effort to engage your fellow classmates regarding the comments provided or the problem that has been solved. Please think about the questions and your peers' responses and reply thoughtfully and courteously, according to netiquette rules. Use good English grammar, correct punctuation, and complete sentences. While the posts will mostly be judged by their thoughtfulness and completeness, I reserve the right to take off points for grammatical errors, especially if they interfere with the clarity of your post.
