CHEM 103: Elementary Chemistry

In this exploration, we delve into the fundamental units of various substances, whether they are single atoms, molecules, or formula units. We examine ionic compounds like Rb?O and Fe(NO?)?, characterized by formula units as their basic components, and covalent compounds like N? and N?F?, where molecules are the fundamental units.

In this video, we delve into the fascinating world of evolutionary adaptations in heme-containing proteins.

Discover how to determine the density of mineral oil and a metal ball bearing using a graduated cylinder. Learn the method of calculating the mass difference and volume to deduce the density and radius of the ball. Watch a detailed physics experiment explained step by step.

Explore how to calculate the mass and volume of ethylene glycol, a common antifreeze, using its density. Understand the essentials of density-related calculations.

Explore the polarity of Carbon disulfide, Sulfur dioxide, Methane, and Chloromethane. Learn how molecular shape influences electron distribution. Understand which molecules possess a net dipole moment and which ones don't.

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.
