CHEM 2: General Chemistry

Discover the process to determine the quantity of ammonia (NH?) required to produce a specific amount of ammonium sulfate ((NH?)?SO?). Through a step-by-step explanation, learn the application of the balanced chemical equation and molar mass conversions. Transform theoretical chemistry into practical knowledge with this insightful guide.

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

Learn about mass changes in an iron bar when exposed to moist air, including the formation of rust (Fe?O?) and how to calculate the final mass.

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.

Unravel electron configurations for transition metals including zinc copper zirconium and iron. Understand how atomic number influences electron arrangement based on the Pauli exclusion principle Hund's rule and the Aufbau principle. Decode the configurations of each metal with clarity.

Discover how to precisely calculate mass, moles, formula units, and atoms in various compounds. Understand the concept with examples like chromium(III) sulfate decahydrate, dichlorine heptoxide, and lithium sulfate. Master chemistry calculations through a step-by-step guide.
