CHEM 142: General Chemistry II

Grasp the fundamental concept of moles in chemistry by equating it to the universally understood notion of a dozen. This video breaks down the usage of Avogadro's constant demonstrating calculations from moles to particles and vice versa. Using real-world examples like Carbon atoms Sulfur Dioxide molecules and Iron atoms viewers gain a clear understanding of moles and particle conversions

This explanation delves into the phenomenon where the reaction rate decreases over time due to the decrease in reactant concentration, resulting in fewer successful collisions and reactions, without revealing specific examples or findings.

Explore the reactivity of different bases in this chemistry comparison. We'll analyze the strength of H?S?, CH?O?, CH?OH, Cl?, CH?COO?, and CH?CHClCOO? in various reactions.
