Assembly - If you missed class I copied notes for you. Come in and get them.
Regular Chemistry and Honors -
Starter -
Given a 55.8 g Popsicle at -15 C is left out on a hot day and all evaporates away, how much energy did it take?
Addition for Honors - Also added this to starter. In a chemical magazine find and article and read it. Summarize it and tell how it involves chemistry. Then we talked about the term project and received the rubric for it. You will get time in class to work on it next time. To summarize the project. You and your lab partner are business partners 10-30 years in the future. You are making a new product that involves chemistry. You are advertising for a position in your plant that involves chemistry. One of you will make a 1/2 size poster to post in the 2300 hall to recruit for the job. The other will be creating a Google.doc to share with me at showell@dsdmail.net The person that creates the Google document, and if you so choose the other student will present to a group of potential employees a 2-4 minute summary. These will be due Feb 17.
Corrected: Assign 3.2
Lecture: Hess' Law, standard heats of formation. Free energy ∆G, Entropy ∆S, Gibbs Free Energy Equation
Hindenburg Video
Homework - Worksheet 3.3 on H, G and S
A site to help you with thermochemistry.
Summary -
1. What do each of the following with a triangle in front of mean ∆H, ∆G and ∆S.
2. What does a positive and negative on each mean?
3. How do you find them?
Student journal was handed in at the end of the period.
