MBC 1240: General Chemistry II

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

Explore the intricacies of endothermic and exothermic reactions through everyday examples. Delve into the energy dynamics of ice melting and water freezing, while emphasizing the importance of the heat change (?H) in these processes.

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

Unravel the concept of propeller twist and its role in aviation and marine propulsion. We'll delve into the science and engineering behind this intriguing phenomenon, shedding light on its applications and significance.

This discussion explores the nature of hydrogen peroxide as a compound composed of hydrogen and oxygen atoms and categorizes it as either a homoatomic or heteroatomic molecule.

Explore the concept of the degree of unsaturation in hydrocarbons. Understand its importance in revealing double bonds, triple bonds, or rings. Learn through examples like limonene, squalene, and lycopene.
