CH 351: Biochemistry

This discussion explores the importance of the size of protein molecules, highlighting their three-dimensional structures, diverse functions, and the role of large size in enabling structural motifs, functional regions, and stability without revealing specific examples or findings.

Determine the molarity of a NaOH solution through titration with sulfurous acid. Starting with the ideal gas equation we derive the concentration of a 0.200L SO?-derived H?SO? solution. Concluding with a molarity of 1.64 M for NaOH using calculated values.

In this tutorial, we break down the principle of density, illustrating it as a measure of mass per unit volume. Using an osmium cube as a practical example, we walk viewers through the steps of computing its density, demonstrating the interplay between mass, volume, and particle arrangement.

Explore the distinction between homogeneous and heterogeneous mixtures. Through real-world examples like baby oil, chocolate chip cookies, and wine, understand their uniformity, phases, and how components are distributed.

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

Explore the properties of various molecules like diazene, hydrogen peroxide, and carbon tetrafluoride. Understand the influence of molecular shape and electronegativity on polarity. Discover why some are polar while others are nonpolar based on their structure.
