CHEM 420: Inorganic Chemistry

Unravel the science behind endothermic and exothermic processes by studying vaporization and condensation. Grasp the molecular changes involved and understand the role of heat in these transformations. A comprehensive look into why vaporization requires heat, while condensation releases it.

Explore the fascinating discovery of a glucose polymer with alternating glycosidic linkages. We'll visualize its Haworth projection and investigate its potential role in organisms, pondering whether it primarily serves a structural or energy storage function. Additionally, we'll discuss which types of organisms might utilize this unique polysaccharide as a potential food source.

Learn about mass changes in an iron bar when exposed to moist air, including the formation of rust (Fe?O?) and how to calculate the final mass.

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

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.
