Purpose This lab report identifies gas produced by chemical reactions and tests for oxygen, hydrogen or carbon dioxide. Your lab report should include the following sections: 1. Responding - Reaction time of HCl and Mg Controlled - Size of Mg piece, amount of HCl in test tube, room temperature, method of agitation. A.) University. Social Issues Research Paper: Chm420 Lab Report. Be familiar with the safe handling procedures for this material before starting work in the lab. The first step of the experiment was to prepare the 2M HCl solution for Part A. For Graham’s Law experiment, the rate diffusion for ammonia is 0.0659 cmsec-1 while for HCl is 0.0432 cmsec-1. This video outlines the experimental portion of the classic HCl/DCl rovibrational spectroscopy experiment performed at Swarthmore College. Creating Coacervates. Academia.edu is a platform for academics to share research papers.
