CHEM& 110 Chemical Concepts w/ Lab • 6 Cr.
Presents the topics of chemistry in a relatively non-mathematical way and focuses on the social and environmental roles of chemistry. Course covers atomic and molecular structure, measurement, the periodic table, and acids and bases. The laboratory expands upon the course materials. Same as CHEM 100. Only one of the two (CHEM 100 or CHEM& 110) may be taken for credit.
After completing this class, students should be able to:
- Define chemistry and identify its major sub fields
- 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, compound, and heterogeneous and homogeneous mixtures.
- Describe the differences between chemical and physical properties
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 such examples 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 our model of the atom
- 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
- Explain that every substance, 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.
State of Matter
- Describe the characteristics of a solid, liquid, and gas in terms of visible properties and the kinetic-molecular theory of matter.
- Apply knowledge of states of matter to current issues such as water and air 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.
- Develop informed opinions on chemical matters affecting society by applying critical thinking skills to evaluate public issues and current events involving chemistry.
- Identify and use key reference material in libraries and on the Internet to research a topic related to chemistry
- Analyze data by distinguishing between opinions, interpretations, and solid evidence.
