CHEM 145: Chemistry for Allied Health Sciences I

This video discusses how the electronegativity of attached groups affects the strength of acids. Comparing pairs such as Chloroacetic vs Fluoroacetic and Acetic vs Nitroacetic acids, we highlight which is the stronger acid in each pair and why.

Unpack the difference between quantitative and non-quantitative observations. Examples include a person's weight on the Moon and the depth a hand pump can reach. Learn why precise measurements are crucial in scientific studies.

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.

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.
