Includes the study of dimensional analysis; atomic structure; stoichiometry; molarity; the periodic table; nomenclature; reactions and equations, and properties of gases. This course is for students majoring in science, engineering, mathematics, pharmacy, or other pre-professional programs who would benefit from further preparation for the standard general chemistry sequence required in these programs. May not be used to satisfy elective requirements for the AS in Chemistry program. Students in other programs should consult with their program advisor about eligibility for use as an elective. Three hours of lecture and two hours of laboratory per week.
Goals, Topics, and Objectives
- Calculations: exponential and scientific notation
- Measurements: metric system, significant figures
- Dimensional analysis: units conversions, problem solving, percentages
- The nature of matter: phases, mixtures, compounds, and elements
- Basic atomic theory: atoms, protons, neutrons, electrons, and ions
- Periodic table: symbols, names, periods, groups, atomic weights
- Nomenclature; naming compounds and writing formulas
- Chemical equations: balancing, molecular, and ionic
- Stoichiometry
- Properties of gases
- Introduction to safety in the chemistry laboratory
- Use a calculator to evaluate mathematical expressions involving scientific notation
- Solve problems using dimensional analysis (unit conversion)
- Distinguish among elements, compounds (both ionic and covalent), and mixtures
- Determine the structure of atoms and ions in terms of subatomic particles including electron configuration and orbitals.
- Predict chemical and physical properties using the periodic table
- Name chemicals from formulas for simple ionic and binary compounds and common acids. Common "ate" ion formulas should be committed to memory
- Write formulas from names of chemicals for simple ionic and binary compounds and common acids. Common "ate" ion formulas should be committed to memory
- Write and balance chemical equations, including molecular and ionic forms
- Identify oxidation numbers, the substance oxidized, the substance reduced, the oxidizing agent, the reducing agent, product of oxidation and product of reduction.
- Solve chemical problems using mole conversions
- Solve stoichiometry problems (mole-mole, mole-mass and mass-mass problems) using dimensional analysis
- Perform calculations involving common concentration units (mass per-cent and molarity)
- Describe properties of ideal gases
- Solve problems involving gas laws
- Apply principles of safety rules and demonstrate knowledge of the location of common laboratory and safety equipment
- Demonstrate proficiency in the use of chemical equipment
- Analyze and interpret measurement data, using mathematical models, and/or observed chemical behavior, expressed in chemical equations, to draw conclusions regarding the nature of matter
- Demonstrate cooperative learning skills
- Demonstrate use of critical thinking skills in analyzing data, making connections and relating to chemical patterns
Assessment and Requirements
Students will be assessed in lecture using exams, assignments/quizzes, and a comprehensive final. Students will be assessed in lab using reports, quizzes and lab-exams. The overall course grade is determined using the categories and values listed below.
| Category | Percentage |
|---|---|
| Lecture Exams | 40-50% |
| Laboratory (reports, quizzes, lab-exams) | 25% |
| Assignments/Quizzes | up to 10% |
| Final Exam | 25% |
No student will receive a passing grade in CHEM 111 unless that student has earned at least a 55% in the laboratory.
Outcomes
- Natural Sciences
- Category 6: Natural Sciences (Lecture and Lab)
