Use the enthalpy of formation values to calculate ΔH using:

ΔH=∑ΔHf∘(products)−∑ΔHf∘(reactants)

What your result tells you about the reaction

How this supports Hess’s Law (use the words path-independent or state function)

💡 Use sentence starters like:

“My ΔH shows that this reaction is _______________.”

“This supports Hess’s Law because…”

“Even if the reaction had more steps, the ΔH would stay the same because…”
