Chemistry Unit 3 Day 3

Learning Objective: Students will learn about heat transfer during chemical reactions by conducting a lab and will analyze and interpret their data in writing using technical vocabulary (endothermic reactions, energy transfer, heat transfer, thermodynamics, reactants, products) and science ideas (processes, cause and effect)

Questions:

1. What would you tell a classmate about spontaneous reactions? (brain)
2. What is an endothermic reaction? (book)
3. Which of the following best describes H₂(g) + Cl₂(g)  2HCl(g), H = -184.6 kJ/mol?

Answer Choices for number 3:

	A. The reaction requires heat. B. The reaction produces heat. C. The reaction is endothermic. D. The reaction has no activation energy. Exit Ticket for Day 3:  What did we do in lab today? (summarize) Why did we do this lab? (explain)
