What This Document Is
This is a post-laboratory assignment for CHM 116 General Chemistry II at Arizona State University, specifically focused on the “Nuclear Chemistry” lab – an experiment estimating the half-life of a “radioactive” element using Skittles® candy. It’s a student submission by Kemari A. Lee, dated March 20, 2024, and worth 30 points.
Why This Document Matters
This assignment is intended for students who have completed the Nuclear Chemistry lab. It serves as a record of experimental data, observations, and analysis. Students submit this post-lab to demonstrate their understanding of the concepts explored in the lab and their ability to apply them to a practical, albeit simplified, model. It’s a graded component of the course.
Common Limitations or Challenges
This document represents *one student’s* work. It’s a completed assignment, not a guide to completing the lab or understanding the underlying principles. It doesn’t provide instruction on nuclear chemistry concepts or the experimental procedure itself.
What This Document Provides
The full document includes: a photograph of the student in lab attire with PPE and Skittles; recorded data from two trials of the Skittles half-life experiment (Tables 1 & 2); a brief description of the observed data trends; a comparison of the two trials; and a scatter plot visualizing the data using graphing software. The document also includes notes regarding missing PPE due to a delayed lab kit. This preview does *not* include the student’s data tables or graph, nor does it provide any analysis beyond what is stated here.
