CHEM 136: Introductory Chemistry

Unravel the concepts of 'Molar Solubility' and 'Solubility Product' to gauge salt solubility. Explore how Calcium Phosphate dissociates in solutions and calculate its unique Ksp value.

This video explains the importance of the number of valence electrons in an element's chemical behavior and demonstrates how to determine the valence electrons for potassium, calcium, and aluminum based on their positions in the periodic table. Valence electrons dictate an element's reactivity with other elements, making this knowledge essential for understanding chemical reactions.

This video provides ground-state electron configurations for various elements, including germanium, iron, zinc, nickel, tungsten, and thallium, based on their atomic numbers.

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.

Discover the intricacies of the electron configuration for phosphorus, from its atomic number to its orbital notation. Learn about unpaired electrons, energy levels, and the significance of inner-shell electrons. Understand how orbital structures define an element's properties.

This discussion explores the nature of hydrogen peroxide as a compound composed of hydrogen and oxygen atoms and categorizes it as either a homoatomic or heteroatomic molecule.
