CHEM 1025: Introductory Chemistry

This video provides ground-state electron configurations for various elements, including germanium, iron, zinc, nickel, tungsten, and thallium, based on their atomic numbers.

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.

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.

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.

Learn how to determine the weight of white gas carried by a backpacker using its density. A valuable skill for hikers and campers.
