CHEM 315: Analytical Chemistry

This video shows you how to balance equations from the reaction of lead(II) sulfide with hydrochloric acid to ammonia's interaction with oxygen. Understand the nuances of atom balancing and grasp the precise stoichiometric relationships.

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.
