CHEM 105: Chemistry and the Environment

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.

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.

Learn how to create Lewis structures for various molecules and assign charges where needed. Understand the molecular connectivity and electron distribution.

Unravel the electron configurations of diverse ions and discern their noble gas resemblances. Understand how atoms and ions strive for full outer electron shells for ultimate stability.

Explore the fascinating world of intermolecular forces in this brief video, featuring HCl, F?, and C?H?? molecules. Learn about the bonds that hold these substances together!

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.
