CHEM 111: General Chemistry 1

This video discusses how the electronegativity of attached groups affects the strength of acids. Comparing pairs such as Chloroacetic vs Fluoroacetic and Acetic vs Nitroacetic acids, we highlight which is the stronger acid in each pair and why.

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.

Unravel the electron configurations of diverse ions and discern their noble gas resemblances. Understand how atoms and ions strive for full outer electron shells for ultimate stability.

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.

Learn about mass changes in an iron bar when exposed to moist air, including the formation of rust (Fe?O?) and how to calculate the final mass.

In this instructional video, we explore the conversion of various pressure units into atmospheres, covering mmHg, bars, Torr, and kPa. The process involves utilizing conversion factors to ensure accurate results for each unit. By the end, you'll have equivalent pressures in atmospheres for the given values, enhancing your understanding of pressure conversions.
