Hess's Law states that the 'Enthalpy Change' is independent of the pathway. This wheel focuses on the math of combining equations to find Delta H. It contains 60+ entries including Standard Heats of Formation, Bond Enthalpy, and Calorimetry constants. On a spin, the student must 'Reverse' or 'Multiply' an equation to fit a target reaction (e.g., land on Multiply by 2, explain how the Delta H also doubles). This is a core tool for AP Chemistry. It builds 'Algebraic Chemistry' skills, helping students master the accounting of energy in complex industrial and biological reactions, providing a rigorous background for engineering.
