CHEM 106: General College Chemistry

Learn the steps to make a 2.5 L of 0.100 M KCl solution from a 5.5 M stock solution in this easy-to-follow tutorial.

This video delves into the significance of electron configurations in understanding an atom's chemical behavior. It examines and corrects inaccuracies in the electron configurations of Aluminium (Al), Boron (B), and Fluorine (F). For instance, the electron configuration for Aluminium is initially presented with an incorrect number of electrons in the 2p subshell, stressing the importance of adhering to the rules of electron configuration for precise atomic representation.

This video provides insights into determining the acid strength of various isomers by examining the ease of proton removal and the stability of the resulting anion. By comparing Propanamine to Trimethylamine and Methoxyethane to Propanol, we determine which compounds are more acidic.

In this video, we explore the information that knowledge of the number of protons in a neutral element's atom can provide. Options for determining neutron count, electron count, and identifying the element's name are examined, with a conclusion that it allows us to know both the number of electrons and the element's name.

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.

Learn how to determine the number of moles in a given set of atoms using Avogadro's number. This tutorial breaks down the calculation for Aluminum and Iron, simplifying the concept for better understanding.
