Course Description:
The General Chemistry series presents a detailed study of the qualitative and quantitative principles of chemistry for four-year science-related degrees (Science, Engineering, Pre-Med, Pre-Dental, Pre-Pharmacy, Pre-Vet, etc.). This 6-credit course includes a laboratory component requiring up to 3 hours in lab during the assigned lab period (see above). The second quarter of the three-quarter General Chemistry series, CHEM 162, focuses on the following topics: equilibrium and factors that influence the extent of gas-phase, and acid-base reactions, kinetics (the study of reaction rates), thermodynamics (the study of energy, entropy, and the spontaneity of a reaction), and electrochemistry (the study of oxidation-reduction reactions that either result in or can be induced by an electric current). This 6-credit course includes a laboratory component requiring up to 3 hours in lab during the assigned lab period. (See day and time indicated above.)
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, including real versus ideal gases.
• Describe intermolecular forces and chemical bonds and how they influence physical and
chemical properties and phase transitions.
5. PHYSICAL AND CHEMICAL CHANGES AND REACTIONS
• 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.
• Describe how a system and surroundings exchange energy at the microscopic and
macroscopic levels.
• Distinguish between spontaneity, reaction rate, and the extent of a reaction.
• Describe various systems at equilibrium and the effects of temperature, pressure,
concentration, and energy on dynamic equilibria.
