CHEM 1211: Principles of Chemistry I

This video elucidates the method to sketch Lewis structures for the radical species ClF? and BrO?. Highlighting the distinguishing feature of an unpaired electron, we illustrate the bond arrangements and lone pairs that define these unique chemical entities.

Master metric unit conversions with step-by-step examples, including cm to meters, g to kilograms, cm to millimeters, and mL to liters.

Learn how to create a Lewis structure for the perbromate ion, ensuring all atoms achieve zero formal charges. Follow the step-by-step guide to understand the bonding and electron distribution in this chemical compound.

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.

Discover how to choose the right indicator for a titration involving Potassium hydrogen phthalate (KHP) and a strong base. Grasp the calculations from molar mass to pH and understand why Thymolphthalein is the ideal choice for a change near pH 8.95.

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.
