CHM 228: Organic Chemistry 2

Explore the world of oxidizing and reducing agents in chemistry. Gain a clear understanding of what they are and how they function without delving too deep into the subject matter.

We explore Lewis structures, which depict atom bonding and lone electron pairs. We create Lewis structures for potassium, barium, aluminum, and bromine by using group numbers in the periodic table to determine their valence electrons.

Explore the process of determining the number of water molecules in a barium chloride hydrate. Through a reaction with sulfuric acid, the video highlights how to derive the formation of barium sulfate and its mass calculations. A comprehensive chemical analysis leads to finding the elusive 'x' value, revealing the water-to-salt ratio.

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.

Learn the method to calculate the mass of a substance using its density and volume. This video demonstrates the practical application of density in determining the mass of carbon tetrachloride (CCl4) from a given volume.

Learn how to determine the weight of white gas carried by a backpacker using its density. A valuable skill for hikers and campers.
