CHB 1251: General Chemistry 1 for Chemistry and Biochemistry Majors

In this video we clarify why lattice energy in solids is always a positive value due to the energy needed to separate ions making it an endothermic process. On the flip side hydration energy is always negative as it releases heat when ions dissolve in water making it an exothermic reaction. We use sodium chloride as a real-world example to illustrate these crucial thermodynamic concepts

Discover how to calculate the vapor pressure of a glycerin solution when mixed with water at a specific temperature. A valuable chemistry lesson.

Explore the world of oxidizing and reducing agents in chemistry. Gain a clear understanding of what they are and how they function without delving too deep into the subject matter.

This video guides you through calculating the theoretical yield of a product in moles for a given chemical reaction by identifying the limiting reactant. It explains how to determine the limiting reactant for different quantities of reactants and then calculates the corresponding moles of the product, ensuring an accurate theoretical yield estimation.
