CHEM 145: Chemistry Freshman Seminar

This explanation delves into the phenomenon where the reaction rate decreases over time due to the decrease in reactant concentration, resulting in fewer successful collisions and reactions, without revealing specific examples or findings.

Uncover the science behind boiling points and molecular interactions in this video. Explore why Dimethylamine boils at a higher temperature than Trimethylamine, despite having a lower molecular weight, and gain insights into the role of molecular structures in determining physical properties.

Explore the chemical reaction between Aluminum and Iron (III) Oxide commonly used in welding. Learn to calculate the mass of Aluminum Oxide formed and identify the excess reagent. Dive deep into molar mass conversions stoichiometry and real-world applications in this chemistry tutorial.

This video provides ground-state electron configurations for various elements, including germanium, iron, zinc, nickel, tungsten, and thallium, based on their atomic numbers.

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.
