Curated OER
Heat of Formation using Hess's Law Lab
For this heat of formation worksheet, students determine the heat of formation for magnesium by combining 3 given reactions and using Hess's Law. Students then complete a data calculations chart for each reaction.
Curated OER
Heat of Reaction
In this reactions worksheet, students define enthalpy, heat of formation, and Hess's Law. Students determine how many kilojoules are released during specific reactions. This worksheet has 6 short answer questions and 11 problems to solve.
