CHEM 220: Organic Chemistry 1

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.

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 perform dilution calculations for solutions, including copper(II) nitrate, calcium chloride, and lithium carbonate, to achieve specific concentrations.

Learn the process of determining the density of a rectangular metal bar using its measurements. Understand how volume and mass play a crucial role in the calculation, and the importance of representing results with the correct number of significant figures

Learn how to find the density of silver using weight and water displacement. A step-by-step guide to a common laboratory technique.

Explore the distinction between homogeneous and heterogeneous mixtures. Through real-world examples like baby oil, chocolate chip cookies, and wine, understand their uniformity, phases, and how components are distributed.
