What This Document Is
This document is a completed solution set for Preliminary Exam 1 in Cornell University’s Engineering General Chemistry (CHEM 2090) course, taught by Professor Marohn, from the Spring 2019 semester. It represents a student’s completed exam, showcasing answers to a range of chemistry problems.
Why This Document Matters
This resource is valuable for students currently enrolled in or preparing for CHEM 2090 at Cornell. It serves as a study aid, allowing students to review example problems and assess their understanding of key concepts covered in the first preliminary exam. It’s particularly useful for identifying areas where a student’s approach might differ from the expected solutions. It’s intended for self-assessment and understanding the expected level of detail and problem-solving skills.
Common Limitations or Challenges
This document provides *solutions* but does not offer detailed explanations of the underlying chemical principles. It won’t teach the concepts themselves, nor does it provide alternative solution methods. Relying solely on this solution set without understanding the core chemistry will not adequately prepare a student for future exams. It is a completed exam, not a teaching tool.
What This Document Provides
The full document includes:
* Completed answers to all questions on the February 28, 2019, CHEM 2090 Preliminary Exam 1.
* Problems covering atomic structure, stoichiometry, empirical and molecular formula determination, and solution chemistry.
* Worked problems demonstrating the application of chemical principles.
* A periodic table, physical constants, and equations are included at the end of the exam.
This preview *does not* include detailed explanations of the solutions, nor does it provide a comprehensive review of the underlying chemical concepts. It only shows the format and types of questions included on the exam.
