Thermochemistry Equations & Formulas - Lecture Review & Practice Problems

This chemistry video lecture tutorial focuses on thermochemistry. It provides a list of formulas and equations that you need to know as well as the appropriate units. It provides a nice review covering topics such as the internal energy of a system, the surroundings, endothermic vs exothermic processes, work, pressure, and volume. It explains the difference between work done on the system vs work done by the system. It also shows you how to calculate q, the amount of heat absorbed or released by a system for processes that involve a temperature change or a phase change including the specific heat capacity concept of water. This video also discusses thermochemical equations and reactions and how to do thermochemical stoichiometry and conversions. This video contains plenty of examples and practice problems.

    Just an FYI for you, towards the end of your video when you have the equation (-393) + 2(-286) - (-785) ..... You calculated that 2*-286 was 576.. but it is actually 572. which would make the actual answer to the equation be 180. just thought i would mention.... LOVED the video though, really helped me better understand.. I have a midterm on Saturday .. here to hoping I pass.
