CHEM 107: General Chemistry II

Discover how to calculate specific rotations of samples using a polarimeter in this informative chemistry tutorial. Explore optical activity and learn step-by-step calculations for two real-world examples. Enhance your understanding of specific rotation and its application in chemical analysis.

In this video, we delve into the concept of percent composition by mass, exemplified through the compound chloroform (CHCl?), which was once employed as an inhalation anesthetic despite its associated toxicity. By calculating the percent composition for each element within the compound, we gain valuable insights into its composition and its potential effects on health and properties.

Classify substances into various categories: element compound homogeneous mixture and heterogeneous mixture. This video breaks down the fundamental distinctions between pure substances and mixtures illustrating with real-world examples like urine pure water a Snickers™ bar and soil. A concise guide for understanding the essence of material classification in chemistry.

In biochemistry, polymers are essential macromolecules, including carbohydrates, lipids, proteins, and nucleic acids, each adopting specific shapes and performing vital functions within cells, with proteins serving diverse roles, nucleic acids carrying genetic information, catalysis expediting reactions, and the genetic code enabling protein synthesis.
