CHEM 420: Inorganic Chemistry

Explore the power of chemical names and symbols in deciphering copper compound formation at each step of the copper cycle, with an illustrative example.

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.

The scenario involves an archaeologist analyzing iron in an old building containing nickel-63, which has a known half-life of 92 years. With only 0.78% of the original nickel-63 remaining, the goal is to estimate the year when this discovery was made. We delve into the calculations and principles of first-order decay reactions.

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.

This video provides insights into determining the acid strength of various isomers by examining the ease of proton removal and the stability of the resulting anion. By comparing Propanamine to Trimethylamine and Methoxyethane to Propanol, we determine which compounds are more acidic.

Discover how amino acids, specifically glycine, form the foundation of proteins. Understand and visualize the Lewis structure representation of glycine. Grasp the significance of atomic bonding and electron distribution.
