Kemtec™ AP™ Chemistry Kits: Determining Molar Enthalpy Using Hess's Law

Includes

Three bottles; Hydrochloric Acid, 1.0N; Magnesium Ribbon, 2g; Magnesium Oxide, 5g

Requires

Thermometers, balances, basic lab supplies and styrofoam cups

This calorimetry lab uses reliable reactions as students measure temperature changes, determine the calorimeter constant and ultimately calculate the molar enthalpy of formation for magnesium oxide using Hess's Law.

Students compare lab results to standard values.
