8. I can complete a Hess’s Law calculation. 

A = simple questions – correct process with one error/omission or complex questions - correctly manipulates one equation. 

M = simple questions correct answer with units and 3 sig fig or complex equations – correct process with one error/omission

E = complex equations – correct answer with units and 3 sig fig.

1. Do Now - Brainstorm what you remember about enthalpy from last year. 

2. Copy down Ms Garlick's notes on Hess's Law. Part of the notes, she will be using the 2023 Questions 2b and 3c. (2023 Marking Schedule)

3. Mahi Choice 

   1. • Work on the following sciPAD pages. Remember, you don't need to complete all the pages or questions, just do what you need until you understand the material. In fact, Ms Garlick is happy if you just read the notes from these pages. 

        • • • Energy Changes - Level 2 Recap (pages 70-71)

            • Changes of State (page 72)

            • Latent Heat  (pages 73-74)

            • Standard Enthalpy of Combustion (page 90)

            • Standard Enthalpy of Formation (page 91)

            • Calculations Using ΔfH (pages 92-93)

            • Hess's Law (pages 94-95)

            • Multiply Through Equations and the Enthalpy Change (pages 96-97)

            • Hess's Law Using Enthalpy of Combustion and Formation (pages 98-99)

      • Work on the No Brain Too Small Enthlapy Collated Questions (not only do the Hess's Law questions, skip the others. We'll cover than in the next lesson.)

4. Work on "CPR" Quiz #4 - Hess's Law (Answers)
