Course description:
This 5‐credit course provides an introduction to the qualitative and quantitative principles of chemistry for non‐science majors and students enrolled in two‐year allied health science programs (Nursing, Dental Hygiene, Respiratory Care, etc. This course covers the following topics: the scientific method, measurements and the metric system, dimensional analysis and problem‐solving, matter and energy, atomic theory, chemical bonding and intermolecular forces, chemical nomenclature, chemical reactions, stoichiometry, solutions and concentration, acid‐base reactions and pH, reaction rates, equilibrium, and nuclear chemistry. This 5‐credit course includes a 3‐hour laboratory component.
1. GENERAL SCIENCE, LABORATORY SCIENCE, AND MICROSCALE
• Apply the scientific method and use empirical data and observations to construct a
sound scientific explanation.
• Distinguish between macroscopic observables and the underlying microscopic
properties of matter by interpreting and representing matter using molecular‐level
drawings.
• Develop good laboratory practices in conducting experiments and reporting
experimental results (including the proper application of significant figures, precision,
and accuracy).
2. CHEMICAL PROBLEM SOLVING
• Develop strong problem‐solving skills that are supported by basic algebraic and
numeracy skills.
• Demonstrate fluency in chemical vocabulary and symbolic representation.
• Use measurable quantities of matter to determine physical and chemical properties.
• Use stoichiometric calculations to predict quantities.
3. ATOMS, MOLECULES AND IONS
• Describe the general structure of an atom.
• Explain the historical development of the atomic theory and the evolution of the
current modern atomic model.
• Explain the relationship between the position of an element in the periodic table and
its physical/chemical properties, including periodic trends.
• Describe the differences in the structure and properties of substances based on
different types and models of bonding.
4. STATES OF MATTER: GASES, LIQUIDS AND SOLIDS
• Compare and contrast the properties of the three states of matter.
• Use kinetic‐molecular theory to explain gas behavior.
• Describe intermolecular forces and chemical bonds and how they influence physical
and chemical properties and changes.
5. PHYSICAL AND CHEMICAL CHANGES AND REACTIONS
• Recognize and describe changes in heat and temperature associated with physical and
chemical changes.
• Classify and balance chemical reactions and predict products for different types of
reactions.
• Apply the properties of ionic and molecular substances in aqueous solution to describe
systems and predict behavior.
• Recognize what factors influence reaction rates.
• Distinguish between chemical and nuclear reactions
