Course Description
Study of non-ideal solutions, chemical equilibria, thermodynamics, kinetics and nuclear chemistry. PREREQUISITE: CHEM A180. Transfer Credit: CSU; UC. C-ID: CHEM 120S as CHEM A180 and CHEM A185.C-ID: CHEM 120S as CHEM A180 and CHEM A185.
Course Level Student Learning Outcome(s)
- Use unit equations and algebraic methods to solve computational problems in the areas of unit conversion, chemical equilibria, thermodynamics, electrochemistry, and kinetics.
- Use equilibrium expressions and the principle of Le Chatelier to calculate the concentrations of species in chemical systems at equilibrium and to predict the changes that occur in response to perturbations to chemical systems at equilibrium.
- Use the atomic theory and kinetic molecular theory to explain the properties of solids, liquids, gases, and solutions, and to describe the changes that occur on a molecular level as matter changes phases.
- Apply thermodynamic properties such as enthalpy, entropy, and free-energy to describe the behavior, energy changes, and spontaneity of chemical reactions.
- Apply safe and proper laboratory techniques to make accurate, reproducible measurements of masses and volumes, and accurate, reproducible experimental observations.
Course Objectives
- 1. Describe the meaning and common usage of terms important in general chemistry.
- 2. Explain observations which are new to them in terms of the principles of chemistry.
- 3. Use the important systems of chemical nomenclature to name compounds new to them; or given the name, write the formula.
- 4. Predict and write correct balanced chemical equations and properly interpret chemical equations.
- 5. Describe the nature of aqueous solutions and pertinent equilibria.
- 6. Analyze and solve unfamiliar chemistry problems in an organized and logical manner.
- 7. Correctly use laboratory equipment in a safe manner with good results.
- 8. Quantitatively evaluate precision and accuracy of experimental results.
