What This Document Is
This document provides updated procedures specifically for Lab 2, “Understanding Chemicals and Moles,” within the General Chemistry I lecture course (CHM 113) at Grand Canyon University, as of Fall 2022. It serves as a supplement to the official online lab manual and lab slide deck, clarifying expectations for lab work and post-lab assessment. It details necessary materials, safety precautions, and a revised workflow for completing the experiments.
Why This Document Matters
This document is essential for students enrolled in CHM 113L who are preparing to perform the lab experiments. It ensures students are aware of any changes to the standard lab procedures and understand the specific requirements for data recording, submission, and assessment. It’s used *during* the lab session for guidance and *after* the lab for completing the required post-lab quiz. Successfully navigating this lab requires adherence to these updated procedures.
Common Limitations or Challenges
This document focuses *solely* on the procedural aspects of the lab. It does not provide the underlying chemical theory, detailed explanations of concepts like empirical formulas or mole calculations, or comprehensive safety training. Students are expected to have a foundational understanding of these concepts from the course lectures and the main lab manual. It also does not replace the need for careful listening to and interaction with the lab instructor.
What This Document Provides
This document includes:
* A list of the lab components to be completed this semester (Parts A, C, and D). Part B is omitted.
* A detailed materials list for Part A: Empirical Formula.
* Specific safety information regarding Magnesium (Mg) and Magnesium Oxide (MgO), including links to Safety Data Sheets.
* Step-by-step instructions for setting up and performing Part A, including burner operation and cooling procedures.
* Detailed instructions for data submission via Halo, including PDF formatting and cloud storage options.
* Information regarding the post-lab quiz on TestMoz and the Dropbox due date.
This preview does *not* include the full experimental procedures for Parts C and D, the actual data tables for recording observations, or the content of the post-lab quiz. It also does not include the theoretical background necessary to understand the experiments.
