CHEM 1516: General Chemistry 2

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.

Learn how to determine the number of moles in a given set of atoms using Avogadro's number. This tutorial breaks down the calculation for Aluminum and Iron, simplifying the concept for better understanding.

Dive into the chemical reaction between Barium Chloride and Sodium Sulfate. Through step-by-step calculations, discover how to determine the resultant mass of Barium Sulfate. Conclude with a real-world example, highlighting the precise amount formed.

Uncover the distinct behaviors of hydrochloric acid and acetic acid in water. Learn about the complete ionization of strong acids and the partial ionization of weak ones, emphasizing the differentiation in proton donation.

Discover the incredible speed of light as it zips 7.5 times around Earth in just a second! Marvel at its daily and yearly travels, equating to billions and trillions of kilometers. Dive deeper into the concept of a 'light year' and its significance in astronomical measurements.

This video explores the processes of rusting in iron and burning a match, addressing whether the observed changes in mass violate the law of conservation of mass, and explains how these processes align with the law.
