CHEM 1041: Fundamental Concepts of Chemistry Laboratory

Discover the monatomic ions formed by potassium and iodine in this informative chemistry tutorial. Learn how to determine ion charges based on atomic properties and their positions on the periodic table.

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 how to calculate the mass and volume of ethylene glycol, a common antifreeze, using its density. Understand the essentials of density-related calculations.

Discover the importance of calculating percent error to assess the precision of experiments. Through real-world examples like measuring alcohol's density and the mass of gold, learn how this value offers insights into measurement accuracy and ways to refine methods.

This video delves into the fascinating world of energy storage in animals and plants, offering insights into why fats are the primary energy storage compound in animals (except muscles) and why plants opt for alternative strategies instead of using fats and oils.
