CEM 834: CEM 834

Learn the art of precise chemical calculations in this video. Discover how Chromium(III) oxide reacts with hydrogen sulfide to form chromium(III) sulfide and water, all while unraveling the necessary steps to determine the exact quantities involved.

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.

Understand the fundamental distinctions between pure substances and mixtures. Unpack the definitions and real-world examples of elements, compounds, homogeneous, and heterogeneous mixtures.

We explore Lewis structures, which depict atom bonding and lone electron pairs. We create Lewis structures for potassium, barium, aluminum, and bromine by using group numbers in the periodic table to determine their valence electrons.

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.

This video discusses how the electronegativity of attached groups affects the strength of acids. Comparing pairs such as Chloroacetic vs Fluoroacetic and Acetic vs Nitroacetic acids, we highlight which is the stronger acid in each pair and why.
