CHEM 3323: Organic Chemistry II

The scenario involves an archaeologist analyzing iron in an old building containing nickel-63, which has a known half-life of 92 years. With only 0.78% of the original nickel-63 remaining, the goal is to estimate the year when this discovery was made. We delve into the calculations and principles of first-order decay reactions.

Explore the fascinating discovery of a glucose polymer with alternating glycosidic linkages. We'll visualize its Haworth projection and investigate its potential role in organisms, pondering whether it primarily serves a structural or energy storage function. Additionally, we'll discuss which types of organisms might utilize this unique polysaccharide as a potential food source.

In this video, we explore the information that knowledge of the number of protons in a neutral element's atom can provide. Options for determining neutron count, electron count, and identifying the element's name are examined, with a conclusion that it allows us to know both the number of electrons and the element's name.

Learn how to perform dilution calculations for solutions, including copper(II) nitrate, calcium chloride, and lithium carbonate, to achieve specific concentrations.

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.

Learn how the ideal gas equation is derived from Boyle's law, Charles’ law, and Avogadro's principle, unraveling the fundamentals of gas behavior.
