CHM 122: Introduction to Organic Chemistry

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 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.

Discover the contrasting processes of vaporization and condensation and their thermal nature. Understand why boiling is endothermic, absorbing heat, while condensation is exothermic, releasing heat, and how these processes impact ?H values.

Understand the process of calculating formula masses for various compounds. This video breaks down the atomic masses for elements in barium bromide, dinitrogen trioxide, copper(I) sulfate, and hydrobromic acid. Master the method of summing up the masses considering atom count in each formula.

Explore the distinction between homogeneous and heterogeneous mixtures. Through real-world examples like baby oil, chocolate chip cookies, and wine, understand their uniformity, phases, and how components are distributed.
