CHE 321: Organic Chemistry

Learn a practical application of chemistry and mathematics in your daily life. Whether you're a tea or coffee enthusiast, this video offers valuable insights into scale removal and maintaining your kitchen appliances.

Unravel the science behind endothermic and exothermic processes by studying vaporization and condensation. Grasp the molecular changes involved and understand the role of heat in these transformations. A comprehensive look into why vaporization requires heat, while condensation releases it.

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

Explore the distinction between homogeneous and heterogeneous mixtures. Through real-world examples like baby oil, chocolate chip cookies, and wine, understand their uniformity, phases, and how components are distributed.

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.
