CHEM 5145: Analytical Chemistry 210

In this video we explore the process of calculating the weight percent of barium potassium and chlorine in a mixed sample of barium chloride dihydrate and potassium chloride. Through a step-by-step approach we examine the changes in sample weight after heating to 160°C breaking down the calculations for each elemental content.

Explore the process of heat absorption and discover how to calculate the final temperature of a lead fishing weight after absorbing a specific amount of heat.

Discover the differences between physical and chemical changes using common examples. Understand how sugar reacts in various scenarios, and how metals undergo changes, either maintaining their substance or forming new compounds.

In this video, we delve into the fascinating world of evolutionary adaptations in heme-containing proteins.

Explore the diverse structures of C?H?? alkyl groups and classify them into primary, secondary, or tertiary categories. Through a visualization of carbon atom arrangements, uncover the nuances of n-pentyl, sec-pentyl, tert-pentyl, isopentyl, and neopentyl structures.

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.
