CHM 116: General Chemistry II

This discussion delves into the use of acetone as a solvent for removing water from laboratory glassware, exploring the science behind its effectiveness and the role of hydrogen bonding in facilitating rapid evaporation.

Uncover the science behind boiling points and molecular interactions in this video. Explore why Dimethylamine boils at a higher temperature than Trimethylamine, despite having a lower molecular weight, and gain insights into the role of molecular structures in determining physical properties.

Explore the world of oxidizing and reducing agents in chemistry. Gain a clear understanding of what they are and how they function without delving too deep into the subject matter.

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.

When water boils, bubbles rise to the surface, but what's in these bubbles? Let's evaluate the options. Option d, water vapor, is correct; the bubbles during boiling are primarily composed of water vapor, the gaseous state of water.
