General Chemistry II (For Majors)

Course Description

CHM1046C – General Chemistry II is a 4-credit, integrated lecture-and-laboratory course that continues the majors-track general chemistry sequence begun in CHM1045C. The course covers the principles of physical and inorganic chemistry needed for upper-division coursework: intermolecular forces and the properties of liquids and solids; properties of solutions and colligative properties; chemical kinetics; chemical equilibrium; acids, bases, and pH; aqueous equilibria and buffer systems; thermodynamics (entropy, free energy); electrochemistry; and an introduction to nuclear chemistry. The integrated "C" format means lecture and laboratory meet as a unified course; students apply theoretical concepts directly through laboratory experimentation each week.

The course sits within the Florida Statewide Course Numbering System (SCNS) under Physical Sciences > Chemistry and is offered at approximately 25 Florida public institutions. CHM1046C is the second course in the year-long majors-track general chemistry sequence and is the prerequisite for organic chemistry (CHM2210/CHM2211), biochemistry, and most upper-division chemistry, biology, and pre-health coursework.

As with CHM1045C and CHM2045C, the SCNS code CHM1046C is used at Broward College, Valencia College, Miami Dade College, St. Petersburg College, and other Florida College System institutions; CHM2046C is the equivalent code used at the State University System (UF, FSU, USF, UCF, FIU) and at some Florida College System institutions including Seminole State. The course content is essentially equivalent, and both transfer into the SUS chemistry sequence.

Special Information

Articulation and Transfer

CHM1046C is part of the Florida common course numbering system and articulates seamlessly to all SUS institutions. A grade of C or higher is required at most SUS institutions for the course to satisfy major prerequisites and to allow use as a prerequisite for organic chemistry and upper-division coursework.

CHM1046C vs. CHM2046C

Both CHM1046C and CHM2046C are majors-track second-semester general chemistry courses with essentially equivalent content. The distinction parallels the CHM1045C/CHM2045C distinction:

• CHM1046C is used at Broward College, Valencia College, Miami Dade College, St. Petersburg College, and many Florida College System institutions.
• CHM2046C is used at UF, FSU, UCF, USF, FIU, Seminole State College, and others.

Both transfer into the SUS chemistry curriculum and satisfy the same prerequisite for organic chemistry. Students transferring should not assume their grade in one will automatically apply to the other; consult the receiving institution.

Position in the Chemistry Curriculum

CHM1046C is followed by CHM2210 (Organic Chemistry I) and CHM2211 (Organic Chemistry II) at most institutions. The full sequence (general chemistry I and II + organic chemistry I and II) is the standard preparation for biochemistry, the MCAT, the DAT, and admission to most U.S. medical, dental, and pharmacy schools.

Prerequisites

The standard prerequisite is CHM1045C (or CHM2045C) with a minimum grade of C. Some institutions also list MAC1105 (College Algebra) or higher mathematics as a prerequisite or co-requisite.

Course Format and Workload

CHM1046C is generally considered more difficult than CHM1045C. Expect 3 hours of lecture and 2–3 hours of laboratory each week, plus 10–15 hours per week of out-of-class study. Equilibrium and acid-base topics are particularly mathematically demanding; the integrated nature of the topics (kinetics, thermodynamics, equilibrium, and electrochemistry interconnect) requires consistent weekly engagement and disciplined problem-solving practice. Strong performance in CHM1046C is the single best predictor of success in subsequent organic chemistry.

Course Code Variations

Florida institutions title this course "General Chemistry II" or "General Chemistry with Qualitative Analysis II." Lecture and laboratory may be offered as separate courses (CHM1046 + CHM1046L, or CHM2046 + CHM2046L) at some institutions; the integrated "C" version is the most common format.
