CHEM 100 Chemical Explorations • 5 Cr.
Presents basic concepts of chemistry using a relatively non-mathematical approach. Topics include measurement, atomic and molecular structure, the periodic table, chemical vs. physical changes, acids and bases, and the social and environmental role of chemistry. Same as CHEM& 110. Only one of the two (CHEM 100 or CHEM&110) may be taken for credit.
After completing this class, students should be able to:
- Chemical Terms
- Define chemistry and identify its major subfields
- Distinguish between matter and energy
- List and describe the key elements of the scientific method
- State the differences between laws and theories
- Recognize and use prefixes in metric measurements
- Apply density as a way to relate the volume to the mass of a substance
- Chemical Elements and the Periodic Table
- Describe the general structure of the atom
- Identify the subatomic particles which make up the atom
- Define atomic number and isotope; identify the number of electrons, protons, and neutrons in a specific atom
- Distinguish mass number from atomic weight
- Extract information about an element from the periodic table: for example; the symbol, atomic number, atomic weight, and the number of protons and electrons
- Explain the differences between elements, compounds, and homogeneous and heterogeneous mixtures
- Describe the difference between chemical and physical properties/changes
- The Chemical Equation
- Explain the concept of the mole
- Compute molar masses of elements and compounds
- Distinguish between empirical and molecular formulas
- Balance simple chemical equations
- Interpret the information conveyed by a balanced chemical equation
- Show knowledge of the role of chemical reactions in their lives using examples such as acid rain, photosynthesis, industrial synthesis, pharmaceuticals, etc.
- Atomic Structure and the Periodic Table
- Explain the historical development of atomic theory
- Identify some of the scientists who contributed to our model of the atom.
- Describe the role of spectroscopy in the development of atomic theory
- Compare and contrast the Bohr model with the modern atomic model
- State the relationship between the atomic structure of an element and its position in the periodic table.
- Describe the historical development of the periodic table
- Identify the location of groups and periods, metals and nonmetals
- Chemical Bonds
- Explain that every substance and system, living or inanimate, is chemical
- Conclude that a given substance has the same structure whether it occurs naturally or is made synthetically
- Describe briefly the differences between molecular, ionic, and metallic substances, including acids, bases and organic molecules
- States of Matter
- Describe the characteristics of a solid, a liquid and a gas in terms of visible properties and the kinetic-molecular theory of matter.
- Apply knowledge of states of matter to current issues such as air and water pollution.
- Application to current issues
- Synthesize course information and apply it to practical, everyday issues such as acid rain, air and water pollution, limited resources on Planet Earth, etc.
- Develop informed opinions on chemical mattters affecting society by applying critical thinking skills to evaluate public issues and current events involving chemistry.
- Identify and use key reference materials in libraries and on the Internet to research a topic related to chemistry.
- Analyze data by distinguishing between opinions, interpretations and solid evidence
