Chemistry Unit 3 Day 4

Learning Objective: Students will learn about energy transfer by doing a lab 

and will analyze and interpret their data in writing using technical vocabulary 

(endothermic, thermodynamics, spontaneous reaction, entropy, enthalpy) and 

science ideas (energy transfer, cause and effect).


Questions:

1. Does the amount of reactants (baking soda or vinegar) change the amount of heat exchanged in a chemical reaction? (brain)
2. What is thermal energy? (book)
3. Which statement describes the potential energy diagram of an endothermic reaction?

Answer choices for number 3:

A. The potential energy of the reactants is greater than the potential energy of the products. B. The potential energy of the products is equal to the potential energy of the reactants. C. The activation energy of the reactants is less than the activation energy of the products. D. The potential energy of the products is greater than the potential energy of the reactants.
