CHEM 151: Principles of Modern Chemistry I

This video explores the structural and functional differences between sphingomyelins and glycolipids, two types of lipids found in cell membranes, highlighting their commonalities in backbone and fatty acid composition and their distinctive roles in cell structure and recognition.

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.

Discover how to precisely calculate mass, moles, formula units, and atoms in various compounds. Understand the concept with examples like chromium(III) sulfate decahydrate, dichlorine heptoxide, and lithium sulfate. Master chemistry calculations through a step-by-step guide.

This discussion explores the nature of hydrogen peroxide as a compound composed of hydrogen and oxygen atoms and categorizes it as either a homoatomic or heteroatomic molecule.

Learn the method to calculate the mass of a substance using its density and volume. This video demonstrates the practical application of density in determining the mass of carbon tetrachloride (CCl4) from a given volume.
