CHEM 1030: Fundamentals of Chemistry I Laboratory

Delve into the journey of scientific ideas as we discuss how a hypothesis can evolve into a theory, and whether a theory can ever become a law. Uncover the distinctions and connections between these fundamental elements of scientific understanding in this illuminating video.

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

Explore the process of determining the number of water molecules in a barium chloride hydrate. Through a reaction with sulfuric acid, the video highlights how to derive the formation of barium sulfate and its mass calculations. A comprehensive chemical analysis leads to finding the elusive 'x' value, revealing the water-to-salt ratio.

Explore the intricacies of hydrogen peroxide's Lewis structure and its bond characteristics. Understand the differences in bond lengths between H?O? and O?. Delve into the distinction between single and double bonds and their implications.

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 science behind endothermic and exothermic processes by studying vaporization and condensation. Grasp the molecular changes involved and understand the role of heat in these transformations. A comprehensive look into why vaporization requires heat, while condensation releases it.
