This document is a completed post-laboratory assignment for CHM 113, Introduction to Chemistry at Arizona State University, focusing on the Gas Laws. It represents a student’s work demonstrating application of concepts covered in a hands-on experiment conducted on February 21, 2023.
This assignment is intended for students enrolled in CHM 113 to showcase their understanding of experimental procedures, data collection, calculations, and analysis related to gas behavior. It serves as a graded component of the course, assessing a student’s ability to apply theoretical knowledge to practical laboratory work.
This completed assignment does *not* provide instruction on how to perform the experiment or derive the gas laws. It also does not include the original lab instructions or background theory. It is a record of one student’s specific results and calculations.
The full document includes: a PPE photograph, an image of the experimental setup, a table of collected data (temperature, pressure, volume), calculations using Dalton’s Law of Partial Pressures and the Ideal Gas Law to determine moles of oxygen produced, calculations of the percentage of hydrogen peroxide in the starting solution, a percent error calculation, and qualitative observations regarding the effect of temperature on a balloon.
