CHEM 25: Fundamentals of Chemistry

Learn how to determine the weight of white gas carried by a backpacker using its density. A valuable skill for hikers and campers.

This video offers insights into the properties and boiling points of different alcohols and ethers, including antifreeze agents like ethylene glycol. We also discuss how molecular structures and interactions impact boiling points, shedding light on key differences among related compounds.

Explore the fascinating process of calculating the mass of silicon in Earth's crust. Learn how to convert Earth's total mass to grams, determine the crust's mass percentage, and find the silicon's mass within the crust. Discover the scale of silicon's presence in our planet's outer layer.

Discover the fascinating world of chemical reactions with N-Bromosuccinimide (NBS) in Carbon Tetrachloride (CCl4), initiated by light. Explore the bromination process and its effects on molecules like cyclopentene, 2,3-dimethylbut-2-ene, and CH3 toluene, leading to valuable insights into organic chemistry.

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.
