This thermochemistry experiment tracks the movement of heat during an experiment incorporating measurement, data collection, data analysis, and drawing conclusions.
This printable education experiment contains both a detailed teachers' guide, and a student section with question and answer sheets for printing and distributing in the classroom.
Age Level
This experiment is designed for ages 13-18. It can be adapted for physical science or introductory chemistry classes.
Subjects
- Science as inquiry.
- Physical science.
- Data analysis, probability and discrete mathematics.
- Energy diagrams for reactions.
- State functions.
Purpose(s)
- To show how the enthalpy of a reaction changes when the reaction’s is modified.
- To apply the Law of Conservation of energy to a series of related reactions.
- To use an energy diagram to explain Hess's Law.
- To interpret Hess's Law.
Activity Overview
Chemical reactions can be classified into major categories of reactions: synthesis, decomposition, single replacement, double replacement, and combustion. This lab illustrates different types of reactions. Students will write a balanced equation for each reaction and predict the identity of the products. After writing a balanced chemical equation for the reaction, they will respond to additional questions.
