CHEM 136: Inorganic, Organic, Biochem

Delve into the journey of scientific ideas as we discuss how a hypothesis can evolve into a theory, and whether a theory can ever become a law. Uncover the distinctions and connections between these fundamental elements of scientific understanding in this illuminating video.

This discussion revolves around the classification of chemical bonds as ionic, polar covalent, or covalent based on the electronegativity difference between the atoms involved. The general criteria for this classification are explained: a difference greater than 1.7 indicates an ionic bond, between 0.5 and 1.7 signifies a polar covalent bond, and less than 0.5 designates a covalent bond. It then applies these criteria to four specific examples, including the CC bond in ethane (H?CCH?), the KI bo

Explore the power of chemical names and symbols in deciphering copper compound formation at each step of the copper cycle, with an illustrative example.

Learn how to write nuclear equations for positron emission with Co-55, Na-22, and F-18. Explore the fascinating world of nuclear reactions.

In this video we explore the process of calculating the weight percent of barium potassium and chlorine in a mixed sample of barium chloride dihydrate and potassium chloride. Through a step-by-step approach we examine the changes in sample weight after heating to 160°C breaking down the calculations for each elemental content.

Discover the art of writing balanced, complete ionic, and net ionic equations for various chemical reactions. Learn the nuances that differentiate between these equations and watch them applied to diverse chemical reactants.
