CH 221: General Chemistry I

Explore oxidation and reduction processes across four chemical reactions differentiating between acid-base and redox activities. Highlighting key substances and their roles in each reaction.

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.

In this exploration, we delve into the fundamental units of various substances, whether they are single atoms, molecules, or formula units. We examine ionic compounds like Rb?O and Fe(NO?)?, characterized by formula units as their basic components, and covalent compounds like N? and N?F?, where molecules are the fundamental units.

Learn the method to determine the count of SO? molecules, sulfur, and oxygen atoms from a given amount of sulfur dioxide (SO?). Understand the application of Avogadro's number in translating moles to molecules. Grasp key concepts of atomic structure and counting with hands-on examples.

This video discusses the fundamental concept of DNA structure, focusing on the identification of the 3' and 5' ends of a DNA segment, specifically highlighting the sequence AGTCAT and its importance in understanding DNA strand direction for processes like replication and transcription.
