CHEM 1211: Freshman Chemistry I

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.

Understand gas stoichiometry by exploring the Ideal Gas Law, which integrates key laws like Gay-Lussac's, Charles's, Avogadro's, and Boyle's. Discover how this equation helps determine relationships between gas volumes and moles in reactions.

Learn how to convert between various units of measurement, ranging from cosmic distances to everyday lengths. The video takes viewers through the process of translating light-years into miles, yards into centimeters, and incredibly high speeds from cm/s to feet per second. Simplifying complex conversions, this guide offers clarity in the world of physics.

Unravel the chemistry behind precipitation reactions and the creation of insoluble salts. Learn how aqueous ions interact to form solid precipitates, illustrated with examples like silver nitrate and sodium chloride. Understand their significance in fields from water treatment to qualitative analysis.

This video explores the concept of structural levels (primary, secondary, tertiary, and quaternary) in biomolecules, focusing on double-stranded DNA, tRNA, and mRNA to understand the diverse ways these molecules exhibit these structural layers.

Discover the art of writing balanced, complete ionic, and net ionic equations for various chemical reactions. Learn the nuances that differentiate between these equations and watch them applied to diverse chemical reactants.
