CHM 1025: Introduction to Chemistry

Discover the process of naming acids based on their anions and oxidation states. This video breaks down the correct naming of HNO2(aq) by distinguishing its anion and determining its place in the world of mineral acids.

This discussion explores the nature of hydrogen peroxide as a compound composed of hydrogen and oxygen atoms and categorizes it as either a homoatomic or heteroatomic molecule.

Explore the atomic world and the crucial distinctions between lone pair and bonding pair electrons in this insightful video. Delve into the fundamental aspects of atomic structure, electron orbitals, and their roles in chemical bonding, reactivity, and molecule formation.

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.

This instructional video guides you through the process of determining the number of molecules in a given sample. It illustrates the conversion from grams to moles using the molar mass of the substance and then to molecules using Avogadro's number, providing a practical example with ethane (C?H?) to calculate approximately 6.67 x 10²¹ molecules in a 0.334 g sample.
