CHEM 2202: Organic Chemistry 2

Learn about mass changes in an iron bar when exposed to moist air, including the formation of rust (Fe?O?) and how to calculate the final mass.

Explore the protonation of amino acids, specifically valine and threonine, when subjected to a pH lower than their isoelectric points, highlighting the structural changes in their carboxyl and amino groups.

Explore how to calculate the theoretical yield of TiCl? in moles based on different initial quantities of reactants in the chemical equation Ti + 2 Cl? ? TiCl?.

Discover how to precisely calculate mass, moles, formula units, and atoms in various compounds. Understand the concept with examples like chromium(III) sulfate decahydrate, dichlorine heptoxide, and lithium sulfate. Master chemistry calculations through a step-by-step guide.

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

Learn how to compute the freezing point of water at various solution concentrations using the freezing point depression formula. Uncover the relationship between concentration and the lowered freezing points for four distinct solutions. Equip yourself with essential knowledge on the effects of solute concentration on water's freezing behavior.
