CHEM 114: Organic Chemistry I

This video delves into the principles of gas behavior at standard temperature and pressure (STP) and how to determine the volume occupied by a given number of moles of gas under these conditions.

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.
