CHEM 1105: Experimental Chemical Basics

Join us as we delve into the intriguing world of genetic coding and discover how the concept of wobble accounts for variations in codons encoding a single amino acid.

This video explores molar concentration (molarity) and demonstrates the calculation of oxygen's molar concentration in water at 25°C, considering a partial pressure of 0.22 atm by employing Henry's Law and the given Henry's Law constant for oxygen, revealing that under these conditions, there are 2.86 x 10?? moles of oxygen per liter of water, highlighting the significance of understanding these concepts for managing gas dissolution in liquids across varying circumstances.

Discover how amino acids, specifically glycine, form the foundation of proteins. Understand and visualize the Lewis structure representation of glycine. Grasp the significance of atomic bonding and electron distribution.

We categorize elements into representative, transition, inner-transition, and noble gases based on their positions in the periodic table and general characteristics, without revealing specific element classifications.

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.

Compare the acidity of chromium trioxide (CrO?) and chromium (II) oxide (CrO) in water. Chromium trioxide forms strong chromic acid increasing hydronium ions, while chromium (II) oxide has weaker oxidizing properties, resulting in a less acidic solution.
