General Chemistry I (For Majors)

Course Description

CHM1045C – General Chemistry I is a 4-credit, integrated lecture-and-laboratory course designed for students pursuing careers in the sciences, engineering, pre-medicine, pre-pharmacy, and other STEM-track programs. The course covers the fundamental principles of chemistry: atomic theory and structure, the periodic table and periodicity, chemical formulas and nomenclature, stoichiometry, chemical reactions and equations, gases and gas laws, thermochemistry, electronic structure of atoms, chemical bonding (ionic and covalent), molecular geometry and intermolecular forces. 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 27 Florida public institutions. CHM1045C is the standard majors-track first-semester general chemistry course at many Florida College System institutions including Broward College, Valencia College, Miami Dade College, and St. Petersburg College. It is the first course in the year-long sequence with CHM1046C – General Chemistry II, which together form the foundation for all upper-division chemistry coursework and most STEM majors.

Important: CHM1045C and CHM2045C are sister courses, both serving as majors-track general chemistry. CHM2045C is offered at the State University System (UF, FSU, FIU, USF, UCF) and at some Florida College System institutions including Seminole State; CHM1045C is the older code, retained at many state colleges. The course content is essentially equivalent, and both transfer into the SUS chemistry sequence. A separate course, CHM1025C – Introductory Chemistry, is the prerequisite or preparatory course for students who lack high-school chemistry background; CHM1045C is not appropriate for students without that background.

Special Information

Articulation and Transfer

CHM1045C is part of the Florida common course numbering system and articulates seamlessly to all SUS institutions. It satisfies the laboratory science general education requirement under the AA degree and is the standard first majors-chemistry course at most Florida College System 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 upper-division chemistry, biology, and pre-health coursework.

CHM1045C vs. CHM2045C

Both CHM1045C and CHM2045C are majors-track first-semester general chemistry courses with essentially equivalent content. The distinction is primarily institutional:

• CHM1045C is the older SCNS code, retained at Broward College, Valencia College, Miami Dade College, St. Petersburg College, and many other Florida College System institutions.
• CHM2045C is the SCNS code used at the University of Florida, Florida State University, the University of Central Florida, the University of South Florida, Florida International University, Seminole State College, and others. The lower-division 2000-series prefix matches the engineering and science calculus-and-physics sequences (MAC2311, PHY2048).

Both courses 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.

Critical: Don't Confuse with CHM1025C

CHM1025C – Introductory Chemistry is a preparatory course for students lacking high-school chemistry background. It is not the same as CHM1045C/CHM2045C and does not satisfy the chemistry requirement for any STEM or pre-health major. CHM1025C is the recommended preparation for students entering CHM1045C without prior chemistry coursework.

Prerequisites

Prerequisites vary by institution but typically include:

• Mathematics: MAC1105 (College Algebra) with a minimum grade of C, or higher mathematics, or appropriate placement.
• Chemistry background: One year of high-school chemistry strongly recommended; CHM1025C or equivalent for students without high-school chemistry.
• Consult your specific institution's catalog for exact requirements.

Course Format and Workload

CHM1045C is a demanding course. Expect 3 hours of lecture and 2–3 hours of laboratory each week, plus 10–15 hours per week of out-of-class study. Strong algebra skills and disciplined problem-solving practice are essential. Most institutions report attrition rates of 20–40% in first-semester general chemistry; performance is the single best predictor of success in subsequent organic chemistry and pre-health coursework.

Position in the Chemistry Curriculum

CHM1045C is followed by CHM1046C – General Chemistry II (chemical kinetics, equilibrium, acids and bases, thermodynamics, electrochemistry, nuclear chemistry). The full year sequence is the prerequisite for organic chemistry (CHM2210/CHM2211), biochemistry, and most upper-division chemistry, biology, and pre-health coursework throughout the SUS.

Course Code Variations

Florida institutions title this course "General Chemistry I" or "General Chemistry with Qualitative Analysis I." The SCNS code CHM1045C (or its equivalent CHM2045C) is the standard. Lecture and laboratory may be offered as separate courses (CHM1045 + CHM1045L) at some institutions; the integrated "C" version is the most common format.
