CHEM 406: Biochemistry

Discover the differences between physical and chemical changes using common examples. Understand how sugar reacts in various scenarios, and how metals undergo changes, either maintaining their substance or forming new compounds.

Explore the chemical combination of nitrogen and fluorine to produce nitrogen trifluoride. Learn how to determine the limiting reactant and calculate the theoretical yield using stoichiometry principles.

Explore the concept of bond energy with the H-Cl bond as a prime example. Delve into the energy dynamics of bond breaking (endothermic positive ?H) versus bond formation (exothermic negative ?H). Understand how the magnitude remains consistent but signs differ based on energy absorption or release.

This video breaks down the configurations for In In+ In2+ and In3+ distinguishing between diamagnetic and paramagnetic properties. Uncover the oxidation state of Indium in InCl2 and understand its diamagnetic nature.

Learn the art of precise chemical calculations in this video. Discover how Chromium(III) oxide reacts with hydrogen sulfide to form chromium(III) sulfide and water, all while unraveling the necessary steps to determine the exact quantities involved.

Discover the simple yet essential method for counting the number of oxygen atoms in different molecular sets, including molecules and ions.
