CHEM 3351: Physical Chemistry

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.

Learn the method to calculate the mass of a substance using its density and volume. This video demonstrates the practical application of density in determining the mass of carbon tetrachloride (CCl4) from a given volume.

In biochemistry, polymers are essential macromolecules, including carbohydrates, lipids, proteins, and nucleic acids, each adopting specific shapes and performing vital functions within cells, with proteins serving diverse roles, nucleic acids carrying genetic information, catalysis expediting reactions, and the genetic code enabling protein synthesis.

Uncover the intriguing relationship between molecular geometry and polarity in chemistry. Using CO? and CCl? as examples, learn how polar bonds can result in nonpolar molecules. Recognize the role of symmetry in determining molecular polarity.
