Explores and applies principles and applications of chemistry. Emphasis on measurement, components of matter, atomic and molecular structure, quantitative relationships including foundational stoichiometry, and major classes of chemical reactions. CH/CHE/CHEM 221Z is a lecture course; CH/CHE/CHEM 227Z is the laboratory component.
Addendum to Course Description
Chemistry 221 is the first of a three term chemistry sequence designed to provide a year of general chemistry to science majors (5 credits/term). It will meet transfer school requirements for such science majors as: chemistry, physics, chemical engineering, pre-medicine, and other pre-professional programs. The class consists of lecture and laboratory. The lecture time is used to provide the student with foundational chemical concepts and mathematical applications to chemistry. The laboratory re-enforces concepts presented in lecture and provides the student a hands-on opportunity to explore these.
Upon completion of this course the students should be able to:
- Describe the phases and classifications of matter and differentiate between physical and chemical properties.
- Represent physical measurements using SI and derived units and demonstrate systematic problem-solving including unit conversion.
- Use the periodic table to solve problems in chemistry.
- Describe the principles of electromagnetic energy, the Bohr model and quantum theory, and use electron configurations to identify periodic variations in chemical properties.
- Interpret and apply ionic and covalent bonding theories including Lewis structures, formal charges, resonance, molecular structure, and polarity.
- Quantify the composition of substances and solutions.
- Identify and name a variety of elements, ions, ionic compounds, and covalent compounds.
- Write, balance, and classify chemical reactions and solve foundational stoichiometry calculations.
Passing score on the chemistry competency exam or completion of a year of high school chemistry with a grade of C or better within the last three years.
This course fulfills the following GE requirements: Science, Math, Computer Science/AAOT, Science, Math, Computer Science/AS, Science, Math, Computer Science/AAS, Science, Math, Computer Science/AGS, Science, Math, Computer Science/ASOT-B.
