4 cards from this section. Quick, good the night before a test.
What does a coffee-cup calorimeter measure?
Think about reactions that occur in solution.
What is Hess’s Law?
It's about the path independence of enthalpy.
What type of calorimeter would you use for a neutralization reaction in solution?
Think about the environment in which the reaction takes place.
True or False: Hess’s Law applies only to reactions that occur in a single step.
Consider if the number of reactions matters.
If an unknown reaction produces 3000 J of heat in a bomb calorimeter, how can you find the ΔH for that reaction if 0.5 moles of gas were involved?
Total changes in moles of gas will affect the enthalpy calculation.
Calculate the enthalpy change for the following multi-step reaction using Hess’s Law. Consider the associated enthalpy changes from each step.
Keep the stoichiometry aligned while summing up the enthalpy changes.
