CHEM 3811: CHEM 3811

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.

We explore synthesis and decomposition reactions, showcasing examples like the formation of water and its breakdown into simpler substances. We also clarify that while many of these reactions are redox reactions involving electron transfer, some synthesis and decomposition reactions may not necessarily be redox reactions, as seen in specific examples.

This video tackles the classification of boiling water as either a physical or chemical change, examining the provided options. We conclude that boiling is a physical change, as the water's chemical composition remains the same during the transition from liquid to gas.

Learn how to create Lewis structures for various molecules and assign charges where needed. Understand the molecular connectivity and electron distribution.

Discover the intricacies of atomic radius and its trends on the periodic table in this video. Unravel the factors influencing atomic size and explore how elements' positions on the periodic table affect their atomic radii.
