**What This Document Is**
This document is an answer key accompanying an introductory activity focused on ionic and covalent chemical bonding in General Chemistry I. It provides expected responses to engagement questions and data table entries from a PhET simulation exploring the conductivity and ionization of different substances in water. The activity connects microscopic interactions to macroscopic properties.
**Why This Document Matters**
This resource is essential for students enrolled in CHEM 1030 at the Community College of Rhode Island who are learning the fundamental differences between ionic and covalent bonds. It’s used to check understanding *after* completing the “Introduction to Ionic & Covalent Bonding” activity, helping students solidify their grasp of these core concepts. It’s particularly valuable for self-assessment and identifying areas needing further review.
**Common Limitations or Challenges**
This answer key does not *teach* bonding concepts. It assumes prior engagement with the PhET simulation and the initial questions. It also doesn’t provide detailed explanations of *why* certain substances behave as they do – it simply presents the expected outcomes. Students still need to understand the underlying principles to apply this knowledge to new situations.
**What This Document Provides**
The full document includes:
* Defined answers for ionic and covalent bond definitions, and the atomic composition of each.
* Observed conductivity results (yes/no) for pure water, salt solutions, and sugar solutions within the PhET simulation.
* Observed ionization behavior (yes/no) of salt and sugar in water, as visualized in the simulation.
* Melting point and solubility data for water, salt, and sugar, sourced from Flinn MSDS sheets.
* Completed data tables for additional substances (oleic acid, iron(III) sulfate, formic acid) based on MSDS research.
* Answers to analysis questions relating substance properties to bond type.
This preview *does not* include the completed data tables or answers to the analysis questions. It also does not include access to the Flinn MSDS search results.
