CHEM 131: General Chemistry I

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.

Master metric unit conversions with step-by-step examples, including cm to meters, g to kilograms, cm to millimeters, and mL to liters.

Explore the intricacies of electron configurations around the atomic nucleus. Understand the ordered filling of energy levels in atoms like Rubidium, Germanium, and Argon. A deep look into the ground-state configurations of key elements.

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

Uncover the nuances of the CO? molecule's polarity and its electron dynamics. Understand how bending and stretching motions influence its electron density. Grasp the analogy of CO? to a jumping rope, highlighting its overall nonpolar nature.

Explore unique strategies employed by prokaryotes and discover if they possess exclusive mechanisms for handling extreme DNA damage that elude eukaryotes."
