CHEM 341: Organic Chemistry Semester 1

Learn about mass changes in an iron bar when exposed to moist air, including the formation of rust (Fe?O?) and how to calculate the final mass.

Discover how to choose the right indicator for a titration involving Potassium hydrogen phthalate (KHP) and a strong base. Grasp the calculations from molar mass to pH and understand why Thymolphthalein is the ideal choice for a change near pH 8.95.

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."

Explore the differences between physical and chemical properties in substances. Learn some fundamentals of chemistry and understand how substances interact and change.

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 why fluorine, with its seven valence electrons, doesn't form compounds like FH? or FCl?. Understand the role of VSEPR theory, atomic size, and electronegativity in limiting bond formation. Grasp the interplay of geometric challenges and electron repulsion in compound stability.
