CHEM 3753: Introduction to Biochemistry 

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 explores the processes of rusting in iron and burning a match, addressing whether the observed changes in mass violate the law of conservation of mass, and explains how these processes align with the law.

This video explains the importance of the number of valence electrons in an element's chemical behavior and demonstrates how to determine the valence electrons for potassium, calcium, and aluminum based on their positions in the periodic table. Valence electrons dictate an element's reactivity with other elements, making this knowledge essential for understanding chemical reactions.

We explore the impact of increasing the concentration of ethylene glycol in an antifreeze mixture, explaining the resulting effect on the freezing point of the solution by examining its interaction with water molecules.

This video elucidates the method to sketch Lewis structures for the radical species ClF? and BrO?. Highlighting the distinguishing feature of an unpaired electron, we illustrate the bond arrangements and lone pairs that define these unique chemical entities.
