It contains a few questions to consolidate learners’ skills to draw and label the exothermic and endothermic energy profile diagrams.

It contains slides to teach learners to perform calorimetry of neutralization experiment, collect the data, and use the data to calculate the enthalpy change of neutralization.

Files are in PDF and .ppt format to give flexibility to teachers should they feel the need to make some adjustment.

Slide 2-4: slides to visualize exothermic reaction and for students to practice labeling exothermic reaction profile. Teachers can print, cut and give the blank energy profile diagram to students for them to practice labeling the diagram.

Slide 5-7: slides to visualize endothermic reaction and for students to practice labeling exothermic reaction profile. Teachers can print, cut and give the blank energy profile diagram to students for them to practice labeling the diagram.

Slide 8: slide for students to practice drawing AND labeling reaction profile.
Slide 9: model answer for question in Slide 8

Slide 10: slide with question for students to consolidate their recognition and understanding of reaction profile features.
Slide 11: model answer for question in Slide 10

Slide 12: slide with Exam-style questions for students to consolidate their understanding of reaction profile diagram as well as exothermic and endothermic reactions.
Slide 13: model answer for questions in Slide 12

Slide 14: slide for students with instructions for students to complete calorimetry of neutralization experiment and collect the data of ∆T.
Slide 15: model answer for labeling in Slide 14. Teachers should guide students to use the ∆T data students collected in Slide 14 to calculate the heat using Q = mc∆T and ∆H.
