In this video, Mr. Krug shows students the fundamental difference between heat and change in enthalpy. He then walks students through a typical problem involving the calculation of enthalpy of reaction (ΔH). In this problem, students learn how to calculate the enthalpy of reaction for a simple precipitation reaction in the laboratory.
