Hess's Law | Explanation & Example Problem #1

The video tutorial explains Hess's Law, a concept in thermochemistry and thermodynamics, and demonstrates how to solve related problems. It covers strategies for manipulating chemical equations, such as doubling, tripling, or reversing reactions, and provides a detailed example problem. The tutorial emphasizes the importance of ensuring that chemical states and coefficients align correctly to calculate the total enthalpy change. The final calculation reveals an endothermic reaction, highlighting the system's absorption of heat.
