CHEM 101: General Chemistry 1

Discover the differences between physical and chemical changes using common examples. Understand how sugar reacts in various scenarios, and how metals undergo changes, either maintaining their substance or forming new compounds.

Explore the relationship between mass, density, and volume using real-life examples, including water, ethanol, chloroform, and balsa wood. Learn the process of calculating mass and uncover which substance has the highest mass based on given conditions.

This video delves into the significance of electron configurations in understanding an atom's chemical behavior. It examines and corrects inaccuracies in the electron configurations of Aluminium (Al), Boron (B), and Fluorine (F). For instance, the electron configuration for Aluminium is initially presented with an incorrect number of electrons in the 2p subshell, stressing the importance of adhering to the rules of electron configuration for precise atomic representation.
