CHEM 108: CHEM 8A

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.

This discussion highlights the significance of studying chiral molecules in biochemistry, emphasizing their impact on biological activity, molecular recognition, pharmacokinetics, and biomedical research, without revealing specific examples or findings.

This video provides insights into the concept of geometric isomerism in organic chemistry and explains why alkynes, which contain carbon-carbon triple bonds and adopt a linear structure, cannot exhibit this form of isomerism, unlike alkenes with double bonds that restrict rotation.

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.
