Chemistry Unit 3 Day 4

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 is an exothermic reaction?
2. How are exothermic and endothermic reactions different? 
3. Which statement describes the potential energy diagram of an exothermic reaction?

Answer Choices for number 3:

A. The potential energy of the products is equal to the potential energy of the reactants. B. The potential energy of the products is greater than the potential energy of the reactants. C. The potential energy of the reactants is greater than the potential energy of the products. D. The activation energy of the reactants is greater than the activation energy of the products. Exit Ticket for Day 3: Choose one of your classmates thoughts written on the white board. Answer the following questions about the statement you chose: Describe what your classmate was trying to say. (In other words,...) What do you think about what he/she said?
