CHEM 4300: Physical Chemistry

Explore the concept of bond energy with the H-Cl bond as a prime example. Delve into the energy dynamics of bond breaking (endothermic positive ?H) versus bond formation (exothermic negative ?H). Understand how the magnitude remains consistent but signs differ based on energy absorption or release.

We explore Lewis structures, which depict atom bonding and lone electron pairs. We create Lewis structures for potassium, barium, aluminum, and bromine by using group numbers in the periodic table to determine their valence electrons.

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 find the density of silver using weight and water displacement. A step-by-step guide to a common laboratory technique.

Explore the distinction between homogeneous and heterogeneous mixtures. Through real-world examples like baby oil, chocolate chip cookies, and wine, understand their uniformity, phases, and how components are distributed.

Unlock the world of chemical formulas and their atom ratios. Learn to write compounds like CaI?, N?O?, SiO?, and ZnCl? in this chemistry tutorial.
