CHEM 82911: Chem 3341

Discover the effects of intermolecular forces on the boiling point, freezing point, and vapor pressure of various compounds. Learn how hydrogen bonding, ionic bonding, and London dispersion forces influence these properties in different groups of molecules.

Grasp the fundamental concept of moles in chemistry by equating it to the universally understood notion of a dozen. This video breaks down the usage of Avogadro's constant demonstrating calculations from moles to particles and vice versa. Using real-world examples like Carbon atoms Sulfur Dioxide molecules and Iron atoms viewers gain a clear understanding of moles and particle conversions

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

Explore the complex challenges scientists face when attempting to extract respiratory complexes from the inner mitochondrial membrane for an in-depth study of their properties and functions."

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

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