Thermochemical Equations Practice Problems

Need help? Ask me your questions here:
vespr.org/videos/5130b7d19d534...
How much heat gets released or absorbed in a chemical reaction? We'll learn how to calculate this. We will use molar mass and conversion factors to figure out the enthalpy change in exothermic and endothermic reactions, which are represented by thermochemical equations.
