CHEM 106: Basic Inorganic Chemistry

Discover how to calculate the nutritional energy in a bag of chips, and learn the science behind converting excess energy into body fat.

Explore the protonation of amino acids, specifically valine and threonine, when subjected to a pH lower than their isoelectric points, highlighting the structural changes in their carboxyl and amino groups.

Determining the total mass of sucrose solutions at varying concentrations: 4.1% 3.2% and 12.5%. Learn step-by-step calculations to find solution masses containing 12 grams of sucrose. Results: ~292.68g ~375g and 96g for each concentration respectively.

In this video, we demonstrate the creation of Lewis structures for methane, carbon dioxide, hydrogen selenide, and ammonia, highlighting the arrangement of atoms and bonds in each molecule. The video emphasizes the importance of Lewis structures in visualizing atomic bonding and the presence of lone electron pairs.

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

This discussion explores the importance of the size of protein molecules, highlighting their three-dimensional structures, diverse functions, and the role of large size in enabling structural motifs, functional regions, and stability without revealing specific examples or findings.
